Abstract

We present a case report of a patient with conal septal hypoplasia (supracristal) ventricular septal defect (VSD) complicated by aortic insufficiency (AI) and subpulmonic stenosis from a fibrous membrane. The development of AI with VSD is a well-recognized problem. However, the association of VSD, AI, and significant right ventricular outflow tract obstruction (RVOTO) is less common. Mechanisms of RVOTO include prolapse of an aortic valve cusp across the VSD, as well as infundibular hypertrophy or muscle bundles. Technical echocardiographic issues can make the diagnosis of VSD, AI, and RVOTO challenging. The presence of a discrete fibrous subpulmonary membrane is uncommon in this setting.
