Percutaneous approaches for treating mitral regurgitation are under investigation, including repair with the MitraClip percutaneous mitral repair system (Evalve, Inc., Menlo Park, CA, USA), which has undergone extensive preclinical and clinical evaluation in the EVEREST I and II trials. The procedure involves the transcatheter placement of one or two MitraClip devices under echocardiographic and fluoroscopic guidance to restore leaflet coaptation. A desirable feature of any percutaneous mitral valve (MV) repair system is that the device should not impede subsequent surgical repair if needed. To date, the majority of reported MV surgeries after MitraClip device implantation have occurred earlier, within one year of treatment. We herein describe four previously unreported cases of successful surgical MV repair up to five years after MitraClip device implantation, demonstrating that late MV repair remains possible, including after implantation of two clips.
