ANEURYSM OF SINUS OF VALSALVA DISSECTING INTO THE INTERVENTRICULAR SEPTUM - ECHOCARDIOGRAPHIC DIAGNOSIS (A Case Report).

Project description:Aneurysm of sinus of Valsalva dissecting into interventricular septum is a rare entity. We report one such case who was incidentally diagnosed by echocardiography to have this abnormality during evaluation of a clinically suspected isolated aortic regurgitation.

Dissecting aneurysm of sinus of Valsalva into interventricular septum and rupturing into left ventricle through multiple sinuses: a rare case report.

Project description:BackgroundRuptured sinus of Valsalva (RSOV) is a rare disorder, which usually involves the right coronary sinus (RCS) or the non-coronary sinus (NCS) and ruptures usually into the right-sided chambers. Involvement of the left coronary sinus (LCS) and multiple sinuses, rupture into the left ventricle (LV), and dissecting aneurysm of the interventricular septum (IVS) have all been scarcely reported.Case summaryA 24-year-old male presented with complaints of exertional fatigue, palpitations, and chest pain with signs of aortic run-off like wide pulse pressure, collapsing pulse along with cardiomegaly, and a diastolic murmur. Echocardiography revealed sinus of Valsalva aneurysms (SOVAs) involving both the RCS and LCS with RCS aneurysm dissecting the IVS and rupturing into the LV and another multilobulated aneurysm from LCS rupturing into the LV. Findings were confirmed on computed tomography (CT) aortogram, and the patient underwent successful surgical repair.DiscussionSinus of Valsalva aneurysm is a rare disorder which usually ruptures into the right-sided chambers. The involvement of multiple sinuses and rupture into the IVS is extremely rare (<2%). Aneurysm dissecting the IVS can lead to complete heart block (CHB) and sudden death. Involvement of the LCS is reported in <5% cases of RSOV, and rupture of such an aneurysm into the pericardial space may lead to cardiac tamponade and can also lead to sudden death. Clinical examination, electrocardiogram, chest X-ray, 2D echocardiography, and CT all help in the diagnosis. Treatment involves surgical repair of the defect.
