Abstract

Transcatheter mitral valve interventions have emerged as valuable alternatives to surgical repair in high-risk patients, including transcatheter closure of mitral valve perforations. However, there is little experience with percutaneous mitral valve interventions in pediatric patients or patients with congenital heart disease. We report a case of transcatheter closure of a residual mid-leaflet mitral valve cleft in a 19-year-old patient with moderate mitral regurgitation through two defects in the anterior leaflet of a repaired cleft mitral valve using a retrograde approach and a novel device, a Siege Vascular Plug (Merit Medical Systems Inc, UT, USA), with favorable results.
