Comparison of Outcomes of Percutaneous MitraClip Versus Surgical Repair or Replacement for Degenerative Mitral Regurgitation in Octogenarians.

This is a retrospective study comparing outcomes in 25 octogenarian patients undergoing percutaneous mitral valve intervention with the Mitraclip device and 35 octogenarian patients undergoing surgical mitral valve repair or replacement for isolated mitral regurgitation. Mitraclip patients were older, had higher calculated risk scores, and had worse NYHA functional status. At 30 days, there was  a non significant difference in mortality but there were significantly less complications among Mitraclip patients. Patients in the surgical mitral valve repair or replacement group showed better 2-year survival and freedom from more than grade II mitral regurgitation.
