[Treating mitral regurgitation: a surgical and interventional update]

Abstract

Surgical mitral valve repair has constantly evolved to become the standard of care for severe mitral regurgitation (MR) with superior acute and long-term results compared to valve replacement. Minimally-invasive surgical techniques have been successful in reducing operative trauma while yielding equivalent or even superior results compared to the conventional sternotomy approach. However, due to elevated operative risk a growing proportion of patients are not referred for surgery, especially elderly patients with reduced ventricular function and functional MR who often present with relevant comorbidities. It is for these patients that transcatheter-based therapies may represent an attractive option. While most interventional techniques are still in experimental or early clinical stages of development, relevant clinical experience has been gained with the MitraClip® device. For successful implementation of a patient-centered mitral valve program, integration of surgical and interventional treatment modalities within a heart center is of paramount importance. This is best accomplished by an interdisciplinary dedicated heart team consisting of cardiologists and cardiac surgeons.
