METHODS: A 78-year-old male underwent TAVR complicated by avulsion of the native aortic valve leaflet\'s left coronary cusp. He was taken for urgent surgery for cusp resection to prevent thromboembolic complications.
CONCLUSIONS: Native aortic valve leaflet avulsion should be suspected during TAVR in instances of extreme hemodynamic instability after balloon aortic valvuloplasty. As TAVR expands in lower risk patients, surgeons should have a low threshold to intervene surgically to treat native leaflet avulsion or other complications.
方法:一名78岁的男性接受了TAVR,并伴有自体主动脉瓣小叶的左冠状动脉尖撕脱。他被送往紧急手术切除,以防止血栓栓塞并发症。
结论:在TAVR过程中,在球囊主动脉瓣成形术后血流动力学极度不稳定的情况下,应怀疑自体主动脉瓣叶撕脱。随着TAVR在低风险患者中的扩展,外科医生应具有较低的手术干预阈值,以治疗天然小叶撕脱或其他并发症。
