During transapical transcatheter aortic valve replacement (TA-TAVR), the apical closure remains a challenge for the surgeon, having the risk for ventricular tear and massive bleeding. Apical closure devices are already under clinical evaluation, but only a few can lead to a full percutaneous TA-TAVR. We describe the successful use of a 9-mm myocardial occluder (ventricular septal defect occluder) that was used to seal the apex after a standard TA-TAVR (using the Sapien XT 23-mm transcatheter valve and the Ascendra + delivery system). The placement of the nonmodified myocardial occluder was performed through the Ascendra + delivery system, with a very small amount of blood loss and an acceptable sealing of the apical tear. This approach is feasible and represents a further step toward true-percutaneous transapical heart valve procedures. Modified apical occluders are under evaluation in animal models.
在经心尖经导管主动脉瓣置换术(TA-TAVR)过程中,心尖闭合对手术医生来说仍是一项挑战,存在心室撕裂和大量出血的风险。心尖闭合装置已在临床评估中,但只有少数能实现完全经皮TA-TAVR。我们描述了成功使用一种9毫米心肌封堵器(室间隔缺损封堵器),在标准TA-TAVR(使用Sapien XT 23毫米经导管瓣膜和Ascendra +输送系统)后用于封闭心尖。未改良的心肌封堵器通过Ascendra +输送系统放置,出血量极少,心尖撕裂封堵效果可接受。这种方法是可行的,代表了向真正经皮经心尖心脏瓣膜手术又迈进了一步。改良的心尖封堵器正在动物模型中进行评估。
