Abstract

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.
