Conclusions: Results from the Asia-Pacific region show that the MitraClip procedure is effective in reducing mitral regurgitation and has favourable short-term safety outcomes.
Methods and results: The MitraClip Asia-Pacific Registry (MARS) includes data from eight different centres in five countries in the Asia-Pacific region. The primary efficacy outcome was reduction in MR to .2+ at 30 days. The safety outcome was 30-day freedom from major adverse events (MAE), defined as the composite of death, myocardial infarction, non-elective cardiac surgery, renal failure, transfusion of .2 units of blood, ventilation for >48 hours, septicaemia, and new onset atrial fibrillation. A total of 142 patients underwent the MitraClip procedure from February 2011 to October 2013. Fifty-three point five percent (76) of patients had functional MR, 45.8% (65) had degenerative MR and 0.7% (1) had mixed MR. The acute procedural success rate was 93.7% (133). Thirty-one point seven percent of the patients were in NYHA Class I-II at baseline, compared to 82.1% at 30 days (p<0.001). Zero percent (0) of the patients had .2+ MR at baseline compared to 76.8% (109) at 30 days (p<0.001).
Aims: Percutaneous MitraClip therapy has been shown to be safe and efficacious in mitral regurgitation (MR). Our aim was to describe early outcomes in patients from the Asia-Pacific region.
