Prognosis of patients with cardiac failure who develop secondary mitral regurgitation due to dilation is uncertain.  

Highlights TCT 2019

The COAPT study was carried out in 78 centers across the US and Canada and included patients with moderate to severe mitral regurgitation (3 or 4 crossovers) symptomatic despite optimal medical treatment (OMT). 

614 patients were randomized to MitraClip (n=302) plus OMT vs. OMT alone (n=312). Primary efficacy end point was hospitalization for cardiac failure at 24 months and safety end point was the absence of device related complications at 12 months. Of the initial group of patients randomized to OMT, 58 (18.6%) crossed over to MitraClip. Before year 2, the protocol would not allow to cross over.

TCT 2019 presented the 3-year outcomes of COAPT, including crossover patients to test whether MitraClip also would have an impact in events vs. OMT alone patients. 

Primary efficacy end point for hospitalizations for cardiac failure at 36 months was seen 220 times for the MitraClip arm vs 378 for the OMT alone arm (HR 0.49; p=<0.0001). For the safety end point, device related complications were 1.4% and disease progression related complication were 7.4%. 

All-cause mortality for the MitraClip arm was 42.8% (including crossovers at 2 years) vs 55.5% for OMT alone patients (HR 0.67; p<0.001).


In patients with cardiac failure and moderate or severe mitral regurgitation who continue to present symptoms despite OMT, at 3 years, MitraClip reduced hospitalization rate for cardiac failure, improved quality of life, functional capacity and survival compared against optimal medical treatment alone.
