The ascending aorta is the segment between the sinotubular junction and the largest aortic branch vessel, the innominate (brachiocephalic) artery (Fig. These arteries supply blood tothe neckand arms, respectively. This study found that arch lengths and diameters grew significantly as ones age increased. 5. The aim of this type of open-heart surgery is to treat an enlarged section of the aortic arch. An example of data being processed may be a unique identifier stored in a cookie. Normal Ascending Aortic Dimensions. You have more than one aneurysm along the length of the aorta. DOPPLER AV Velocity Time Integral 14.37 cm . Published by Elsevier Inc. All rights reserved. The aortic root diameter is generally taken from the sinuses of Valsalva, while the aortic annulus diameter is taken from the base of the aortic leaflets. The ascending aorta is responsible for carrying oxygen-rich blood from the heart to the rest of the body. The diameter of the ascending aorta should be 5 to 5.5 cm, according to current guidelines. Congenital Heart Disease and Pediatric Cardiology, Invasive Cardiovascular Angiography and Intervention, Pulmonary Hypertension and Venous Thromboembolism, ACC Anywhere: The Cardiology Video Library, CardioSource Plus for Institutions and Practices, Annual Scientific Session and Related Events, ACC Quality Improvement for Institutions Program, National Cardiovascular Data Registry (NCDR). The normal size of the aorta for humans is 1.5 inches. Keywords: Thus, current guideline-recommended normal ranges may need to be adjusted to account for these differences. Only 12/141 children were younger than 6 years . The aortic size paradox is a byproduct of the large number of patients who are in small size ranges. A 4.3 cm ascending aortic aneurysm is a ballooning or dilation of the ascending aorta, the main artery that carries blood from the heart to the body. Compared with indices that include weight, a simpler height-based ratio (avoiding weight assessment and BSA calculation) yields satisfactory results for evaluating the risk of complications among patients with TAAA. Normal right ventricular size. AAO= ascending aorta; DAO = descending aorta; PA =pulmonary artery; RPA = right pulmonary artery; CAPD = chest anterioposterior diameter. Aortic size assessment by noncontrast cardiac computed tomography: normal limits by age, gender, and body surface area. You should be aware that there is a good chance that you will need surgery for aortic aneurysms, but there are many options to consider. All of these diameters can give important information about the size and health of the aorta. Intraluminal aortic diameters should parallel echocardiography and invasive angiography. Aortic morphology of the control group was evaluated to establish normal diameter . . Even though most patients with acute aortic dissection suffer from underlying hypertension, only a tiny fraction of hypertensive individuals ever suffer from dissection. The dimensions of the cardiac chamber, the size of the aorta, left ventricular myocardial performance indexes, and aortic elastic properties, including the global circumferential strain, fractional area change and mean longitudinal strain, were measured serially in . Gransar H, Thomson LEJ, et al. doi: 10.1016/j.echo.2019.08.012. If you experience chest pain, shortness of breath, or other symptoms that suggest a rupture, you should seek medical attention as soon as possible. Obese people, high blood pressure, smoking, and a family history of aortic aneurysm are among the risk factors for ascending aortic aneurysms. D-dimer levels are elevated in acute aortic dissection as well as in pulmonary embolism. TAA/D is most commonly inherited and characterized by low penetrance, variable expression, and a decrease in penetrance. Lowering blood pressure is an important part of immediate aortic dissection management, as is stabilizing the patient. However, a recent study found that the average ascending aorta size in females was 3.5 cm in diameter. If your ascending aorta is enlarged, your doctor will likely recommend lifestyle changes and close monitoring. When youre older, your risk of developing an ascending aortic aneurysm is higher. The thoracic aorta is an important artery that carries oxygen-rich blood from the heart to the rest of the body. Federal government websites often end in .gov or .mil. However, especially among obese individuals, weight probably does not play as important a role as does height in indexing various measures to body size. Your size is not dangerous. Surgery that is elective has a mortality rate of only 5%. [2] [Background] A pulmonary artery to ascending aorta ratio (PA:Ao) is helpful for detecting pulmonary hypertension. A significant difference (P is smaller than 0.001) in aortic root diameters existed between men and women which could not be explained by differences in body surface area. This minimally invasive treatment is ideal for patients who are at high risk for open surgery and offers a therapeutic option for those at risk for open surgery. The total length is about 5 centimetres (2.0in). The descending aorta has three layers of tissue: Tunica intima: This is the inner layer through which your blood flows. There are numerous options for treating your aneurysm, and the best one for you will be determined by its size, location, and other factors. Computer tomography defined a mild to moderately dilated aorta as one with an ascending dimension of 40 to 45 mm on the aortic surface. 8 A diameter greater than 40 cm is generally classified as aneurysmal Figs. The AA is consid-ered dilated or ectatic when its size is 1.1 to 1.5 times larger than the normal and aneurismal when its size exceeds the limits dening . 444 12. For patients with high risk of surgery for the thoracic aorta, endovascular treatment has become an increasingly popular treatment option. A aortic dissection is frequently fatal if the blood flows through the outside aortic wall. Epub 2008 Aug 7. Sizing of the stent graft is according to the dimension of the native non-diseased aorta or true aortic lumen in patients with acute or chronic aortic dissection, with 5-10% oversizing to minimize risk of type Ib endoleak . The er called umc who said they would not even see me at that size, even with symptoms. 75% of individuals have hypertension, and prior cardiac surgery is a risk factor. Rationale and objectives: Two types of factors contribute to the deterioration and increase in diameter of the aorta. The formula D(mm) can be used to calculate the upper normal limit for ascending aortic pressure. The descending aorta is the most extensive part of the aortic system and is the main blood vessel in your body. An ascending aorta, on the other hand, has a mean diameter of only 3.2 cm when not diseased, making it difficult to diagnose. There is no definitive answer to this question as the size of the ascending aorta can vary significantly from person to person. Prospective criteria for recruitment included: age 18 years, no history or symptoms of cardiovascular or lung disease, no cardiovascular risk factors (i.e. Johnson C, Redheuil A, Arai AE, Gomes AS, et al. 5 cm.13, 22, 23 Therefore, it is advisable to refer patients with the size of the . recommend preventive surgery if the aneurysm is in the ascending aorta and greater than 5.5 centimeters (cm), or 2.17 inches (in), across . Age distribution, body size and heart rate were equal between genders. My patients have maintained their aortic aneurysms stable level for more than 10 years as a result of their initial enlarged. Would you like email updates of new search results? A previously healthy woman was taken to the emergency room with severe chest pain and shortness of breath shortly after arriving at the emergency room. A study discovered, however, that aortic dissections can occur at smaller sizes the aortic size paradox. Even as it has been discovered that age, height, body habitus, gender, ethnicity, and even sexual orientation can all influence aortic size, defining what constitutes a normal aortic size is still a difficult task. A long section of the aorta is involved. government site. Surgery is typically reserved for aortic aneurysms that are 5.5 cm or greater in diameter. Adult individuals free of heart, lung, and kidney disease were prospectively enrolled from 15 countries, with even distributions among sexes and age groups: young (18-40 years), middle aged (41-65 years) and old (>65 years). Several cutoff criteria were included. Bethesda, MD 20894, Web Policies Both procedures have the potential to save your life. During the surgery, a portion of the aortic valve and part of the aorta are removed. Right superior panel was axial image at LM, MeSH Aorta, predicted Aorta, standardized Aortic valve regurgitation Aortic valve stenosis Visual assessment of systolic function Left ventricular mass and geometry Left ventricular dimension and volume Left ventricular function (ejection fraction) It comes out of your heart and pumps blood through the aortic arch and into the descending aorta. 49 percent of dissections occurred at sizes of 5 cm or less, while 40% occurred at 5 cm or larger. The combined criterion (pulmonary artery diameter to ascending aorta diameter ratio >1 and/or pulmonary artery systolic pressure 40mmHg) achieved sensitivity of 72%, specificity of 79%, and a negative predictive value of 69%. For an adult female, the normal dimension is between 2.0 and 3.0 cm. MDCT Imaging of Non-Traumatic Thoracic Aortic Emergencies and Its Impact on Diagnosis and Management-A Reappraisal. If the aortic diaphysis is 0.16* and the descending aortic diaphysis is mm, the ratio is 116. Table 40 Absolute and BSA indexed normal values of ascending aortic luminal diameter for men and women of different age categories measured on phase contrast images according to My dissertation research was a study of the effect of experimentally-induced diabetes mellitus on aortic endothelial cell histamine metabolism. My husband's ascending aorta was measured at 3.8 cm two years ago and has remained unchanged two years later. These medications can help to lower blood pressure and improve blood flow through the aorta. A normal aorta, on the other hand, measures only 3.5 cm in size. Aortic leaflet prolapse, usually caused by the dissection flap, is the most common cause of this condition. When there is a tear, blood travels through one channel and then through another. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. In a computer tomography study, a mild to moderately dilated aorta ascended between 40 mm and 45 mm. Results: Causes of Dilatation of the Ascending Aorta. Computer tomography defined a mild to moderately dilated aorta as one with an ascending dimension of 40 to 45 mm on the aortic surface. 2009;193 (4): 928-40. What diameter should your aorta be? Normal values of maximal aortic dimensions at key aortic anatomical locations by contrast-enhanced CTA have been defined. [6] It makes aortic surgery difficult, especially aortic cross-clamping, and incisions may result in excessive aortic injury and/or arterial embolism. In a man, the AsA is considered normal up to 3.8 cm and in women up to 3.5 cm (2). The aorta originates from the left ventricle of the heart and extends upwards through the chest and into the head. 4. Bethesda, MD 20894, Web Policies PMC When an aneurysm is less than 5.5 cm in diameter, the risk of rupture is typically higher than the risk of surgery. and a formula for calculating predicted aortic size by age, gender, and BSA was created. The AAOD increases with age and male gender. The aortic dissection is a serious condition caused by a tear in the main artery of the body (aorta). The ascending aorta is the section of the aorta, the largest artery in the body, that carries oxygen-rich blood from the heart to the rest of the body. The .gov means its official. Thieme. The diameter of the aorta (or more or less) is usually considered to be a surgical target, depending on the patients height. T32 HL007381/HL/NHLBI NIH HHS/United States. AAOD has significant linear association with age, gender, DAOD, and pulmonary artery diameter (P < .05). One option for preventing a rupture of the aortic section is to treat it with an enlarged portion of it. Determinants and normal values of ascending aortic diameter by age, gender, and race/ethnicity in the Multi-Ethnic Study of Atherosclerosis (MESA). The first objective of this study was to investigate whether the correlation of aortic size with age, sex, and body surface area (BSA) is consistently shown in the entire thoracic aorta. The 25% phase has the most motion artifact (white arrows) and 35% phase has the most anterior location, cyclical shape and the least motion artifacts. Aneurysm ruptures are more likely to occur as you age, become overweight, or smoke. Ligurian Group of SIEC (Italian Society of Echocardiography)]. The normal diameter of the ascending aorta has been defined as <2.1 cm/m2 and of the descending aorta as <1.6 cm/m2. It leaves the heart and forms an arch. This is considered to be an enlarged aorta, and can be a sign of a serious underlying condition. The number is expressed in terms of 21 minus 0.16. . A ruptured aortic aneurysm can cause severe bleeding, potentially fatal. Treatment typically involves surgically repairing the aneurysm. Similarities and Differences in Left Ventricular Size and Function among Races and Nationalities: Results of the World Alliance Societies of Echocardiography Normal Values Study. There is no definitive answer to this question as each individual is different and therefore what may be considered normal for one person may not be normal for another. An aortic aneurysm may not grow quickly in some cases, and patients do not need to seek medical attention. Age, sex, and body surface area were significantly associated with these measures at all levels of aorta. MRIs were performed on 73% of subjects as part of the initial examination. 2022 Apr 13:17085381221087816. doi: 10.1177/17085381221087816. The normal value for the descending aorta is 1.6 cm/m2 for BSA, and aneurysm is present when a value of 3 cm is exceeded. Methods: Last, differences in aortic dimensions were also observed according to race: Asians had the smallest nonindexed aortic dimensions at all levels. The dimensions of the ascending aorta can change over time, and they may be different in different people. After receiving my degree, I took an Instructor position at the University of Louisville School of Medicine, where I team-taught human / mammalian physiology. FOIA Aortic aneurysms near the aortic root may be related to Marfan syndrome and other related conditions, and it is possible that surgery to remove part of the aorta and the aortic valve will keep them from becoming larger. Only 8% of the participants had a aorta that was 4.5 cm or more in size; only 99% of the participants had an aorta that was 5.0 cm or more in size. This usually occurs in the chest (thoracic) portion of the artery, but it can also occur in the abdomen. To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. A aortic dissection diagnosis can be made with multiple diagnostic methods such as multidetector computed tomography, transesophageal echocardiogram, and magnetic resonance imaging. Johnson C, et al. Conclusion. Epub 2019 Mar 19. Marfan syndrome, a genetic disorder, is characterized by the weakening of the connective tissue in the body, which can affect the functioning of the heart and blood vessels. It is critical to seek medical advice and to keep a regular schedule of medical checks. Changes in the aortic location, shape and size within the RR interval. What Is The Normal Size Of Your Aorta? Because unaddressed severe carotid disease is a risk factor for stroke during ascending aortic operations, patients over the age of 65 should have duplex imaging of their carotids. The https:// ensures that you are connecting to the In some cases, medication or surgery may be needed. Patients were stratified into four categories of yearly risk of complications based on ASI and AHI. Clipboard, Search History, and several other advanced features are temporarily unavailable. Sudden death can also occur. TAPSE (tricuspid annular plane systolic excursion) is 2.0_ cm (normal > 1.7 cm).

In such cases, an endovascular coiling treatment may be available. It runs up along the left side of the spine and then curves over to the right at about shoulder level. Surgery is typically only recommended if there is evidence of damage to the aorta or if other treatments havent worked. In order to study the aortic size paradox, researchers used a publicly available database of 3,573 multiethnic subjects (46% male, mean age 60.7 years) from the general population. A summary of the evidence. Half of aortic dissections in IRAD study occurred less than the standard intervention criterion of 5.5 cm in ascending aortas, raising concerns. Normal Values of Right Atrial Size and Function According to Age, Sex, and Ethnicity: Results of the World Alliance Societies of Echocardiography Study. Eliason: During an abdominal aortic aneurysm rupture, an individual typically experiences severe abdominal or back pain. The upper normal limit for ascending aorta can be calculated with the formula D (mm) = 31 + 0.16*age and for descending aorta with the formula D (mm) = 21 + 0.16*age. Left, 64 MDCT angiographic image and right, CACS image. sharing sensitive information, make sure youre on a federal Surgery for an enlarged ascending aorta may involve replacing the damaged section of the aorta with a synthetic tube (graft).if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[120,600],'stuffsure_com-large-mobile-banner-1','ezslot_6',185,'0','0'])};__ez_fad_position('div-gpt-ad-stuffsure_com-large-mobile-banner-1-0');if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[120,600],'stuffsure_com-large-mobile-banner-1','ezslot_7',185,'0','1'])};__ez_fad_position('div-gpt-ad-stuffsure_com-large-mobile-banner-1-0_1'); .large-mobile-banner-1-multi-185{border:none !important;display:block !important;float:none !important;line-height:0px;margin-bottom:15px !important;margin-left:auto !important;margin-right:auto !important;margin-top:15px !important;max-width:100% !important;min-height:600px;padding:0;text-align:center !important;}.

Clin Res Cardiol. Similarly, you may ask, what size aortic aneurysm requires surgery? Despite their findings, they made no recommendation regarding intervention criteria based on their study. Careers. Multidetector CT of Thoracic Aortic Aneurysms1. Anneurysms can form in any section of the aortic body, but they are most common in the abdomen and the upper body. Clinical Topics: Cardiac Surgery, Invasive Cardiovascular Angiography and Intervention, Noninvasive Imaging, Prevention, Vascular Medicine, Aortic Surgery, Cardiac Surgery and Arrhythmias, Interventions and Imaging, Interventions and Vascular Medicine, Keywords: Aneurysm, Dissecting, Aortic Aneurysm, Thoracic, Aortic Rupture, Body Size, Body Surface Area, Body Weight, Cardiac Surgical Procedures, Diagnostic Imaging, Dissection, Risk, Secondary Prevention, Vascular Diseases. 2014 Apr;15(4):415-22. doi: 10.1093/ehjci/jet173. What is a normal size of an ascending aorta? Ascending aorta diameters measured by echocardiography using both leading edge-to-leading edge and inner edge-to-inner edge conventions in healthy volunteers. Surgery is frequently recommended in certain situations, but it is not always required. The normal range has to be corrected for age and sex, as well as daily workload. The mean total AAOD was 33.5 and 36.0 mm in females and males, respectively. The ascending aorta is the first part of the aorta, which is the largest blood vessel in your body. It is common for aortic arches to narrow and curvature to decrease as the body ages. Bookshelf The pattern for developing PitAd was also different in MEN4 vs MEN1, with less than 5% risk for developing pituitary neoplasms at a young age in MEN1 compared with 8.9% in MEN4 ( Machens et al. The frequency of aneurysms in men is also higher than in women. AAO, DAO, RPA and, Changes in the aortic location, shape and size within the RR interval. 2022 Mar;35(3):275-277. doi: 10.1016/j.echo.2021.12.001. The best treatment option depends on the individual patients condition. Treatment for an enlarged aorta may include lifestyle changes, medication, and surgery. Methods: A total of 1286 healthy yellow population (52.7 11.0 years, 634 male) who underwent CCTA were retrospectively included in the present study. Because of its size or growth rate, it is typically decided to treat it. The normal growth rate of the aorta is about 0.07 to 0.2 cm/y 5 but . I received my Ph. In this study, the authors found that a simpler measure of aortic diameter indexed to height had similar predictive power compared to aortic diameter indexed to BSA. Among patients with thoracic ascending aortic aneurysm (TAAA), how does aortic diameter indexed to patient height (the aortic height index [AHI]) compare with aortic diameter indexed to body surface area (BSA) for the estimation of the risk of aortic dissection, rupture, or death? and transmitted securely. Between each commissure of the aortic valve and opposite the cusps of the aortic valve, three small dilatations called the aortic sinuses. A type A dissection in an emergency room should be treated immediately, while a type B dissection in an emergency room should be treated after the operation. Four, Optimal sites to measure AAOD. Quality of life after replacement of the ascending aorta in patients . In our study population, the aortic diameter was 3.2 cm (SD 0.4 cm). Conclusions: A total of 1442 consecutive subjects who were referred for evaluation of possible coronary artery disease underwent coronary computed tomographic (CT) angiography (CTA) and coronary artery calcium scanning (CACS) (55 + 11 years, 65% male) without known coronary heart disease, hypertension, chronic pulmonary and renal disease, diabetes, and severe aortic calcification. Boys had larger ventricles than girls . All rights reserved. The aneurysm is growing quickly, 0.5 cm or more over 6 to 12 months, regardless of its size. Ascending aortic aneurysms are defined as a permanent dilatation of the ascending aorta with a diameter 1.5 times the expected normal diameter or an ascending aortic diameter 4 cm in people <60 years 7. Diagnosis, treatment, and long-term management of Kawasaki disease: a statement for health professionals from the Committee on Rheumatic Fever, Endocarditis and Kawasaki Disease, Council on Cardiovascular Disease in the Young, American Heart Association. Figure 3 depicts the distribution of aort sizes from the Pape et al. I received my Ph. In a pilot study, we found that a common KIF6 Trp719Arg variant increased the propensity of thoracic aortic aneurysms (TAA) to suffer dissection (AD). This type of variation, in fact, can protect you from heart disease. Nightingale M, Gregory A, Sigaeva T, et al. The good news is that the survival rate for those who receive treatment is much higher than for those who do not receive treatment; nearly 80% of those who do receive treatment survive for at least six months. I was told I had a 3.2 dilation ascending aorta and to follow up with a doctor. If you are recommended for surgery, open surgery is the most common procedure for aortic aneurysm repair. Thoracic aortic aneurysms (TAA) are defined as aorta diameter greater than 1.5 times the expected size by 11 stakeholder medical societies. At the union of the ascending aorta with the aortic arch the caliber of the vessel is increased, owing to a bulging of its right wall. FOIA Cassottana P, Badano L, Piazza R, Copello F. Cardiol Young. 3. Four panel images of a MDCT scan display the reconstructed images of 15%, 25%, 35% and 95% phase of the RR interval. Please see the reference; . Marfan syndrome, the Loeys-Dietz aneurysm syndrome, vascular Ehlers-Danlos syndrome, Turner syndrome, and familial TAA/D syndrome are all examples of genetic disorders that can result from this condition. ENLARGEMENT OF THE ASCENDING AORTA (AA) is a frequent nding in clinical practice. Measurements, indexed separately by BSA and by height, included the aortic annulus, sinuses of Valsalva, and sinotubular junction. Blood is transported from the peripheral arteries to the upper body via smaller arteries. Before Disclaimer, National Library of Medicine Prolonged hemodynamic stress, as well as cocaine use, pheochromocytoma, and heavy lifting, may all be factors. Medication. Other treatments, in addition to lowering blood pressure and cholesterol, may be available. In other words, a 20-year-old has an upper normal limit for ascending aorta circumference (34 mm), while an 80-year-old has an upper normal limit of 44 mm. If it does, you might have: -Chest pain or pressure -Difficulty breathing -Fainting or dizziness -Heart murmur -Pulse thats not regular. Calculation of percentiles utilizes the published averages and standard deviations for the binned age and BSA groups and assumes a normal distribution of size diameters within each interval. Because it is a less invasive treatment than open surgical repair, the procedure can be used by those who are at risk for surgery. However, if you have any concerns about your dimensions, you should talk to your doctor.if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[320,50],'stuffsure_com-banner-1','ezslot_0',181,'0','0'])};__ez_fad_position('div-gpt-ad-stuffsure_com-banner-1-0'); An enlarged ascending aorta is most often caused by atherosclerosis, which is the buildup of fatty plaque in the artery wall. Left superior and inferior panel were coronal and sagittal images at AAO mid plane. They gave me the number to the doctors at USA in mobile. Epub 2013 May 22. The pain comes in goes. A mildly dilated ascending aorta is an enlargement of the upper part of the aorta, the large blood vessel that carries blood from the heart to the rest of the body. This part of the artery is called arch of aorta. Endovascular grafts have the potential to treat a wide range of complications associated with type B dissections, with low morbidity and mortality. Risk stratification was performed using regression models. That being said, a 4 cm aorta is generally considered to be within the normal range. Boehm PM, Schwarz S, Thanner J, Veraar C, Gerges M, Gerges C, Lang I, Apfaltrer P, Prosch H, Taghavi S, Klepetko W, Ankersmit HJ, Moser B. JTCVS Open. 17 to 33 mm The normal range of aortic root diameters in this group was 17 to 33 mm (mean 23.7). Normal renal function should be ensured with the appropriate blood work, and abnormal results should prompt further investigation. eCollection 2022 Jun. The normal diameter of the abdominal aorta is regarded to be less than 3.0 cm. However, if you are concerned about your aorta size, it is always best to speak with your doctor. These changes may include quitting smoking, eating a healthy diet and maintaining a healthy weight, and exercising regularly. RESULTS Age, BSA, . I was told that based on my size, I will likely need to get it repaired at some point, mainly because it will continue to grow. In addition, we defined normals in our database as those who, after 28 causes of dilated aorta were excluded, were normal both clinically and echocardiographically (n = 2334). A thoracic aortic diameter greater than 3.5 cm is generally considered dilated, whereas a diameter greater than 4.5 cm is generally considered to be a thoracic aortic aneurysm. However, weight might not contribute substantially to aortic size and growth. Endovascular surgery is a less invasive procedure in which a catheter is used to open up the aorta and create a new vessel. Scott MB, Huh H, van Ooij P, et al. It is not uncommon for an enlarged abdominal aorta to be more than 3.0 centimeters long. The average aorta is approximately 2 cm, or slightly smaller than 1 inch. As a result, the risk of dissection is reduced relative to the smallest size range, as shown in line 4. For PHPT, we found a cumulative risk of 1.6% by age 20, 17% by age 40, and 53.5% by age 60 years, compared with 73% already at the age of 50 years in MEN1 (Carty et al. This study confirms that surgical intervention should be performed in a height of 5 to 5.5 cm. Accessibility On the right side, it is in relation with the superior vena cava and right atrium, the former lying partly behind it; on the left side, with the pulmonary artery. The procedure has many benefits. An acute dissection of the patient in the image above occurred a year ago. A specific gene mutation may be identified in a family by screening all of its first-degree relatives for it. In the normal adult the aorta has a diameter of about 3 cm, tapering to approximately 1.75 cm as it bifurcates into the common iliac arteries opposite the fourth lumbar vertebra. The upper limit of standard reference range of the ascending aorta may be up to 4.3cm among large, elderly individuals.[5]. For an adult female, the normal dimension is between 2.0 and 3.0 cm.
