ABSTRACT
@#Objective To investigate the early clinical results of MitraClip system in domestic patients. Methods We retrospectively analyzed the clinical data of 36 patients who underwent transcatheter edge-to-edge repair procedure using MitraClip system in Beijing Fuwai Hospital, Shenzhen Fuwai Hospital and Fuwai Yunnan Cardiovascular Hospital between January and June 2021. There were 24 males and 12 females, with a median age of 70 (47-86) years. Ten (27.8%) patients had 3+ mitral regurgitation (MR) and 26 (72.2%) patients had 4+ MR preoperatively. Results All procedures were successfully performed. The reduction in MR was 2+ at least immediately after surgery, and 91.7% of patients had MR≤2+ at 3 days postoperatively. There was no statistical difference in left ventricular ejection fraction change postoperatively. Forward velocity and peak gradient of mitral valve were increased after the procedure. Mean gradient of mitral valve were increased at 3 days postoperatively than immediately after surgery (P<0.001). Two patients had acute pericardial effusion intraoperatively, and received pericardial puncture and drainage immediately. Conclusion MitraClip system has been applied well in domestic patients and can significantly improve MR. This sutdy has a good consistency with foreign studies, and the early results are satisfactory.
