Acute coronary artery occlusion is a relatively rare procedural adverse event in valve-in-valve transcatheter aortic valve implantation. Here we present a case of a 26-mm Sapien 3 prosthetic valve implantation in a degenerated 23-mm Freedom Solo bioprosthetic surgical valve with subsequent left and right coronary occlusion. Left coronary artery occlusion was managed immediately with the use of an upfront coronary artery protection technique and drug-eluting stent placement. Right coronary artery occlusion presented with right-sided heart failure and cardiac arrest that required resuscitation and additional hemodynamic support. As the artery could not be engaged with a catheter, a combination of intravenous antithrombotic and anticoagulant therapy was used as a successful bailout step to restore adequate coronary flow.
急性冠状动脉闭塞是经导管主动脉瓣置入术(瓣中瓣技术)中相对罕见的手术不良事件。在此,我们报告一例在退化的23mm Freedom Solo生物外科瓣膜中植入26mm Sapien 3人工瓣膜,随后发生左、右冠状动脉闭塞的病例。左冠状动脉闭塞通过使用冠状动脉保护技术和药物洗脱支架置入术立即得到处理。右冠状动脉闭塞表现为右心衰竭和心脏骤停,需要进行复苏和额外的血流动力学支持。由于无法用导管进入该动脉,静脉抗栓和抗凝治疗联合使用作为成功的补救措施,以恢复足够的冠状动脉血流。
