Abstract : Aneurysms of the sinuses of valsalva are rare congenital defects resulting from aortic wall weakness at the junction of annulus fibrosa and the aortic media at any of the 3 cusps.[1] With reference to patients from eastern countries, the most common site of origin is right coronary sinus (65–85%) with nearly all rupturing into right chambers.[1] Thus, an aneurysm of the right sinus of valsalva rupturing into the left ventricle is a very rare condition if at all accurately diagnosed. There is literature available where ruptured sinus of valsalva aneurysm (RSOVA) could only be diagnosed upon transesophageal echocardiography (TEE) and was misdiagnosed on transthoracic echocardiography (TTE) and cardiac catheterization.[2,3] However, this report is about a hemodynamically stable patient who was preoperatively identified as suffering from RSOVA, whereas the actual pathology was different and was only discovered on intraoperative TEE and influenced the surgical technique and cardiopulmonary bypass (CPB) conduct, improving the therapeutic outcome.
