Sinus, Aortic


(1) In mammals (excluding man), the initial, dilated part of the ascending aorta; the same as the bulbus arteriosis.

(2) In man, part of the cavity of the bulb of the aorta, located between the semilunar valve and the aortic wall.

While most of the times it ruptures into the right ventricle or right atrium, rupture into the pulmonary artery is rare,2 accounting for less than 2 % of all ruptured sinuses of valsalva. We report a rare case of ruptured aortic sinus of valsalva aneurysm into the main pulmonary artery.
It is mostly due to anatomical factors including low coronary ostia and shallow sinuses of Valsalva (SOV) and with valve in valve (VIV) for surgical bioprosthesis.
Aneurysms of the sinuses of Valsalva. Cardiology 2006; 106:73-81.
Aneurysms of the sinuses of Valsalva (ASV) are thin-walled outpouchings, most commonly involving the right or non-coronary sinuses.
The coronary arteries arise from two of the three aortic sinuses or sinuses of Valsalva present at the root of ascending aorta.
We found nine cases of RCA + LCA high location, and they can divide into two group: One group is RCA and LCA origin from the ascending aorta above the sinuses of Valsalva separately without abnormal distributing [Figure 2], we classified it to "benign" group; another group is RCA and LCA origin from the ascending aorta above the commissural or the left sinus of Valsalva together, RCA passed between the aorta and PA before reaching the right atrioventricular groove [Figure 3], ostial occlusion due to aortic expansion during exercise may result in myocardial ischemia, so we classified it to "potentially serious" group.

Upon reviewing the literature concerning this topic, no information was found regarding reported cases in which a shunt such as the atrial septal defect was found in association with coarctation of the aorta and even less in combination with aneurysms of the sinuses of Valsalva, aortic root dilatation and bicuspid aortic valve, all in the same adult patient.
Furthermore, baseline echocardiography and aortography (in lieu of CT angiography) suggested that the sinuses of Valsalva appeared to be sufficiently spacious and the height of the coronary ostia from the annulus appeared grossly adequate to accommodate the 23 mm S3 valve without causing coronary artery obstruction from the degenerated prosthetic valve leaflets.
The coronary arteries arise from the aortic sinuses, also called the sinuses of Valsalva. These sinuses are named according to their position as the anterior, left posterior, and right posterior aortic sinuses.
