Double-Committed Subarterial Ventricular Septal Defect with Combined Aortic and Pulmonary Valve Prolapse: A Rare Case Report

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.
