Abstract: Unruptured aneurysms of Valsalva sinus are most often asymptomatic conditions discovered accidentally but with fatal potential whenever complications such as rupture occur. Therefore, whenever incidentally diagnosed, these pathologic conditions should be repaired in order to prevent catastrophic complications and even sudden death. Here we describe a case of an asymptomatic 42 young man with a large unruptured sinus of Valsalva aneurysm (SVA) originating from a noncoronary sinus with a competent tricuspid aortic valve. The diagnosis was made accidentally by transthoracic echocardiography (TTE) and confirmed by computed tomography angiography (CA) and cardiac catheterization. The aneurysm was resected on a cardiopulmonary by-pass, and the sinus was successfully reconstructed with a bovine pericardial patch preserving the competence of the native aortic valve. In conclusion, bovine pericardial patch might be successfully used in order to reconstruct Valsalva sinus in cases presenting aneurysmal dilatation at this level.
