Little is known about the presentation of structural valve degeneration complicating transcatheter heart valves (THVs). We report a case of acute heart failure, secondary to leaflet prolapse, in a previously well 77-year-old man, 7.5 years after successful transcatheter aortic valve replacement with a 26-mm balloon-expandable Sapien XT (Edwards Lifesciences, Irvine, CA) THV. This case highlights that structural valve degeneration complicating THVs might lead to acute presentation with little warning from previous echocardiograms. Calcification might be absent on imaging. Redo transcatheter aortic valve replacement is feasible and appears safe. Post deployment optimization with a highly noncompliant balloon might improve full expansion of the newly implanted THV and improve valve performance.
关于经导管心脏瓣膜(THV)并发结构性瓣膜退变的表现,目前所知甚少。我们报告一例77岁男性病例,该患者既往身体状况良好,在成功植入26毫米球囊扩张式Sapien XT(爱德华生命科学公司,加利福尼亚州欧文市)THV进行经导管主动脉瓣置换术后7.5年,因瓣叶脱垂继发急性心力衰竭。该病例突出表明,THV并发结构性瓣膜退变可能导致急性发作,而之前的超声心动图几乎没有预警。影像学检查可能未发现钙化。再次进行经导管主动脉瓣置换是可行的,且似乎是安全的。使用高度顺应性球囊进行植入后优化可能会改善新植入THV的完全扩张并提高瓣膜性能。
