For this reason, screening with CT scanning is not routinely recommended, but it is the imaging method of choice to diagnose complications of ascending TAA dilatation and for preoperative visualization of the entire aortic anatomy. Trindade P.T. Annals of Translational Medicine. Son J.Y., Ko S.M., Choi J.W., Song M.G., Hwang H.K., Lee S.J. They are greatly dependent on the predisposing condition and, as discussed later, on the management of this disease. The thoracic aorta is further divided into 3 parts: ascending, arch and descending. As Table9, Table10 show, there is decreased 30-day and 5years mortality in patients who undergo the valve sparing procedure. In the lateral view, there is loss of the retrosternal space. In patients with Marfan syndrome, a landmark trial by Shores et al. (2009) ISBN:3131477814. Ferencik M., Pape L.A. Changes in size of ascending aorta and aortic valve function with time in patients with congenitally bicuspid aortic valves. The recent survey revealed that of all the individuals with BAV, 75% of BAV patients will be presenting aortic valve stenosis and dilation of the supra-coronary aorta, 15% aortic insufficiency and dilation of the proximal aortic root, leaving the fate of the remaining 10% undefined [1, 2].These enlist the absence or presence of raphes, if yes then numbers were noted, spatial position of cusps . Benedetto U., Melina G., Takkenberg J.J., Roscitano A., Angeloni E., Sinatra R. Surgical management of aortic root disease in Marfan syndrome: a systematic review and meta-analysis. In addition, a recent study at the Montreal Heart Institute showed that ascending aortas in patients with BAV had a growth rate of 0.1cm per year 1cm beyond the sinotubular junction [31]. Saliba E, Sia Y. Before The ascending aorta sits atop the left ventricle on the left side of your heart. The aorta is the main artery in your body that moves blood away from your heart the highway that disperses oxygen-rich blood. Blood rushes through the tear, causing the inner and middle layers of the aorta to split (dissect). Kabirdas D., Scridon C., Brenes J.C., Hernandez A.V., Novaro G.M., Asher C.R. Measuring the Aortic Root and Ascending Aorta. Aortic dilatation could be easily attributed to hemodynamic abnormalities across an abnormally shaped valve but many studies seem to show that valvular dysfunction is not significantly related to increased aortic size. It is therefore reasonable to recommend screening for first degree relatives of affected people. This syndrome is associated with the COL3A1 mutation and the diagnosis can be made by DNA amplification or by collagen analysis. Patients are encouraged to perform aerobic exercise with moderation. While Marfan syndrome predisposes to many other conditions, its most serious complications are related to aortic valve regurgitation and ascending root dilatation. For instance, the mutation of fibrillin 1 in Marfan syndrome weakens the vascular wall given that it is a reinforcing structure[8] and it also alters the regulation of the bioavailability of TGFB1 [9]. A retrospective study (that included a few patients with Marfan syndrome) showed that the median size associated with an increased risk of aortic dissection, rupture or sudden death was 6.0cm [45]. This disorder is nearly always associated with aortic root aneurysm and they tend to have complications very early on in life. Although, transesophageal echocardiogram (TEE) provides better view of almost the entire thoracic aorta, it is a semi-invasive technique and it is not the preferred routine study for follow-up or screening. Aortic aneurysms can occur anywhere in the aorta.
