Transcatheter Edge-to-Edge Repair in Secondary Mitral Regurgitation With Extended Non–COAPT-Like Features: From the EXPANDed Studies

JACC Heart FailPublished Secondary analysis of the EXPANDed post-market studies

Authors' conclusion

In the EXPANDed studies, non-COAPT-like patients experienced significant improvements in MR, HFH, and quality-of-life at 1 year, comparable with those observed in COAPT-like patients.
