not-yet-known not-yet-known not-yet-known unknown Sinus of Valsalva Aneurysm (SVA) is a rare congenital anomaly, and its rupture can lead to acute heart failure and hemodynamic instability. We present a case of a 32-year-old male who developed acute dyspnea and chest pain following a coughing episode. Echocardiography revealed a left-to-right shunt, and computed tomography angiography (CTA) confirmed a 17 mm rupture at the right sinus of Valsalva, forming an aorto-right ventricular outflow tract fistula. The patient underwent urgent surgical repair, with successful defect closure and no residual shunting postoperatively. This case highlights the role of CTA in diagnosis and the necessity of early surgical intervention.

not-yet-known not-yet-known not-yet-known unknown Double-committed subarterial ventricular septal defect (DCVSD) with combined aortic and pulmonary valve prolapse is an extremely rare congenital anomaly with significant hemodynamic implications. We present the case of a 16-year-old male who presented with fatigue and a pansystolic murmur. Echocardiographic evaluation identified a 12 mm DCVSD with associated prolapse of the right coronary cusp of the aortic valve and the left cusp of the pulmonary valve. This double valve prolapse caused mild aortic and pulmonary regurgitation and significant left-to-right shunting. Given the risk of progressive valvular dysfunction, early surgical intervention was performed. This case highlights the importance of recognizing and managing the rare coexistence of aortic and pulmonary valve prolapse in DCVSD to prevent long-term complications.
