Transcatheter mitral valve repair with MitraClip in patients with pulmonary hypertension: hemodynamic and prognostic perspectives

Transcatheter mitral valve repair with MitraClip has emerged as a possible therapeutic option for patients with severe mitral regurgitation (MR) with high risk for surgical valve repair. MitraClip intervention has demonstrated to improve haemodynamics and clinical outcomes in selected patients in observational and randomized studies. Preoperative pulmonary hypertension (PH) is known to affect prognosis in patients undergoing surgical mitral valve intervention. The aim of the present review is to discuss the available literature focused on the haemodynamic and clinical effects of MitraClip in patients with severe MR and PH.
