The Role of Surgical Treatment of Severe Functional Mitral Regurgitation in Heart Failure.

Patient selection is mandatory to successful mitral valve repair in functional mitral valve regurgitation. Preoperative echo evaluation is critical to better evaluate the anatomic modification of the mitral apparatus. In light of recent randomized trials, several patients could benefit from transcatheter mitral therapy. Mitral annuloplasty is not effective in all patients with functional mitral valve regurgitation; meanwhile, adding surgical techniques should be performed to improve the repair durability.
