PRIMARY outcome

Timeframe: Discharge/30days

Population: The analysis population included all eligible and consented subjects implanted with a MitraClip device. The TTE images at discharge and 30 days were not evaluable by the echo core lab in 2 subjects, hence APS was evaluable for 49 subjects

APS is defined as successful implantation of the MitraClip device(s) with resulting MR severity of 2+ or less as determined by the ECL assessment of a discharge echocardiogram (30-day echocardiogram will be used if discharge echocardiogram is unavailable or uninterpretable).

PRIMARY outcome

Timeframe: 30 days

Population: The analysis population included all eligible and consented subjects implanted with a MitraClip device.

A Major Adverse Event (MAE) was determined as the composite of death, stroke, myocardial infarction (MI), renal failure, and non-elective cardiovascular surgery for device- or procedure-related adverse events occurring after the femoral vein puncture for transseptal access.
