Abstract

Objective The study objective was to report the midterm outcomes of MitraClip implantation in inoperable or high-risk surgical candidates with degenerative mitral regurgitation.

Results Forty-eight high-risk consecutive patients with severe degenerative mitral regurgitation underwent MitraClip implantation (mean age, 78.5 ± 10.8 years; 56.6% of the patients were aged ≥80 years). Mean Society of Thoracic Surgeons score was 12% ± 10%, and 71% were in New York Heart Association class III or IV. Mean left ventricular ejection fraction was 57% ± 11%. The device was successfully implanted in 47 of 48 patients (98%). In-hospital mortality was 2%. The median intensive care unit stay was 22 hours; patients were discharged from the hospital in an average of 4.5 ± 2.4 days. Predischarge echocardiography showed a mitral regurgitation reduction to grade 2+ or less in 43 of 47 patients (91.5%). Actuarial survival was 89% ± 5.2% and 70.2% ± 9% at 1 and 2 years, respectively (82% ± 9% in patients aged

Conclusions MitraClip therapy is a valuable alternative to surgery in high-risk and elderly patients with degenerative mitral regurgitation. Clinical benefits also are obtained in octogenarians.
