A single MitraClip for mitral regurgitation can lead to the development of severe mitral stenosis requiring surgical valve replacement.
MitraClip can induce progressive mitral stenosis necessitating surgery; leaves open optimal patient selection for transcatheter repair in nonischemic cardiomyopathy.
We report a patient with class III heart failure symptoms due to mitral regurgitation (MR) subsequent to nonischemic cardiomyopathy. The patient underwent percutaneous transcatheter mitral valve repair using a single MitraClip, which reduced the MR; however it created mild-to-moderate mitral stenosis, which progressed to severe mitral stenosis. Subsequently the patient underwent mitral valve replacement surgery.
