We report a case of a 35-year-old man presenting with shortness of breath and palpitation on exertion, who was evaluated and found to have a Sub aortic membrane with severe left ventricular obstruction associated with a Right sinus of valsalva aneurysm (RSOV) rupturing into right ventricular outflow tract & perimembranous ventricular septal defect (VSD). A sinus of Valsalva aneurysm is a rare cardiac anomaly that may be congenital or acquired; a coexisting cardiac lesion might be present. Ventricular septal defect can be seen commonly associated with RSOV. However, Sub aortic membrane associated with RSOV is extremely rare. Here, we report for, an unusual presence of Sub aortic membrane with RSOV (Rupturing from right coronary sinus into right ventricular outflow tract) and Perimembranous ventricular septal defect.
