Although PMVR with MitraClip led to improvement in MR, TR, and NYHA functional class in patients with baseline moderate/severe TR, the primary safety endpoint at 30-day was impaired, while moderate/severe TR independently predicted death and re-hospitalization for heart failure at 12-month.
MitraClip implantation in patients with 3+ and 4+ MR is safe and efficacious until mid-term follow up, regardless of patients' gender. Despite improvement in NYHA functional class in both groups, female gender demonstrated a trend toward poorer results. Further validation of our findings is warranted.
MitraClip implantation in patients with expanded baseline echocardiographic features, compared with the control group, was associated with similar rates of safety and efficacy through 12-month follow-up. Further validation of our findings is warranted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
