Transcatheter Closure of a Restrictive Muscular Ventricular Septal Defect Causing Tricuspid Valve Regurgitation in an Adult

Abstract

Ventricular septal defect (VSD) is one of the most common congenital heart defects. Despite high rates of spontaneous closure, an unknown percentage of patients may become candidates for VSD closure if an unresolved defect prompts the development of other cardiac problems.1 The late complications of VSD can manifest as a left-to-right shunt, with the degree depending on associated pressures of the right ventricle: the smaller the defect, the greater the gradient from the left ventricle (LV) to the right ventricle and the louder the murmur, especially in the setting of highly turbulent flow.
