Transcatheter Edge-to-Edge Repair for a Patient With Severe Mitral Regurgitation of Carpentier IIIa Classification.

Whether patients diagnosed with mitral regurgitation of Carpentier class IIIa (rheumatic origin) can possibly be treated with balloon mitral commissurotomy followed by transcatheter edge-to-edge repair remains unclear. Here, we report on such a case who was successfully treated with balloon mitral commissurotomy and then transcatheter edge-to-edge repair without aggravating mitral stenosis. (Level of Difficulty: Intermediate.).
