The aim of the study was to evaluate a balloon expandable transcatheter heart valve (THV) system (Myval) at 6-month follow-up in ovine banding model. Eleven THV systems were implanted via carotid approach. There were 2 procedure-related deaths and 2 premature deaths. At 6 months all valves that completed follow-up (n = 7) were functional, with no significant regurgitation, calcification, thrombi, or vegetation. Mean pressure gradient was 21.9 ± 11 mm Hg, maximum velocity = 3.3 ± 1 m/s, and ejection fraction was 53.3 ± 6%. Myval THV showed optimal hemodynamic performance and biocompatibility.
本研究的目的是在绵羊结扎模型中对球囊可扩张经导管心脏瓣膜（THV）系统（Myval）进行6个月的随访评估。通过颈动脉途径植入了11个THV系统。有2例与手术相关的死亡和2例过早死亡。在6个月时，所有完成随访的瓣膜（n = 7）功能良好，无明显反流、钙化、血栓或赘生物。平均压力阶差为21.9±11 mmHg，最大流速为3.3±1 m/s，射血分数为53.3±6%。Myval THV显示出最佳的血流动力学性能和生物相容性。
