Expanding percutaneous treatment of mitral valve diseases: Transcatheter closure of mitral valve leaflet perforation.

Mitral valve perforation is a rare cause of mitral regurgitation. We present a case of a 16-year-old patient with mitral valve regurgitation after redo-cardiac surgery for recurrent subaortic stenosis. Transthoracic echocardiography revealed a mitral regurgitation with an eccentric jet causing a significant regurgitation documented by the presence of a convergence flow over the hole.
