Risk factors and management experiences of stent valves detachment in transcatheter aortic valve implantation (TAVI) / 中国胸心血管外科临床杂志

ABSTRACT

@#Objective    To summarize and analyze the risk factors and management of artificial valve slippage in transcatheter aortic valve implantation (TAVI). Methods    We retrospectively analyzed the clinical data of 131 patients undergoing TAVI surgery in our center from September 2017 to May 2019, including 62 patients through transapical approach and 69 patients through transfemoral artery approach. Results    A total of 131 patients received TAVI surgery, among whom 4 patients had slipped during the operation, 2 patients via transfemoral artery approach, and another 2 patients via transapical. The average age was 77±9 years with one female (25%). Preoperative evaluation, higher position and poor coaxial were main risk factors for valve slip in TAVI. Conclusion    Valve slippage is also a serious complication in TAVI surgery. Reasonable and effective treatment can avoid thoracotomy.
