Abstract:
Coronary artery obstruction is an uncommon yet devastating complication of transcatheter aortic valve replacement (TAVR) and may necessitate leaflet modification. A 38-year-old man presented to our center with quadricuspid aortic valve with severe aortic regurgitation. Double leaflet modification was performed with the Bioprosthetic or native Aortic Scallop Intentional Laceration to prevent Iatrogenic Coronary Artery obstruction (BASILICA) technique prior to TAVR, creating 6 leaflets from 4. The patient tolerated the procedure well with symptomatic improvement. Follow-up transthoracic echocardiogram showed normal bioprosthetic aortic valve function. This case demonstrates feasibility of this procedure with comprehensive preprocedural analysis and intraprocedural imaging guidance.
摘要:
冠状动脉阻塞是经导管主动脉瓣置换术(TAVR)的一种罕见但破坏性的并发症,可能需要修改小叶。一名38岁的男子出现在我们中心,患有四瓣主动脉瓣并伴有严重的主动脉瓣反流。在TAVR之前,用生物假体或天然主动脉扇贝有意裂伤进行双小叶修饰,以防止医源性冠状动脉阻塞(BASILICA)技术,从4创建6小叶。患者对手术耐受良好,症状改善。随访经胸超声心动图显示生物主动脉瓣功能正常。该病例通过全面的术前分析和术中成像指导证明了该程序的可行性。
