About

The goal of this multicenter, randomized, double-blind controlled study is to learn about the individuals after transcatheter edge-to-edge mitral valve repair (TEER). The main questions it aims to answer are: (1) can enhanced external counterpulsation (EECP) reduce the prevalence of afterload mismatch after TEER? (2) can EECP prevent the major adverse cardiac events after TEER? Participants will be randomly assigned into EECP or Sham-EECP intervention after TEER. Researchers will compare the EECP and Sham-EECP to see if it helps reduce the prevalence of afterload mismatch after TEER.
