应用血管内超声评估经导管主动脉瓣置换术中冠状动脉阻塞风险12例回顾分析
Assessing the risk of coronary artery occlusion during transcatheter aortic valve replacement by intravascular ultrasound:a retrospectire analysis of 12 cases
摘要
Abstract
Objective To investigate the feasibility of intravascular ultrasound(IVUS)in assessing the risk of coronary artery occlusion during transcatheter aortic valve replacement(TAVR).Methods A retrospective analysis was performed on 12 patients with high risk of coronary artery occlusion confirmed by computed tomography(CT)from April 2020 to November 2023 in General Hospital of Northern Theater Command,who were treated with TAVR and assessed by IVUS during the procedure for the possibility of coronary artery occlusion.Results A total of 12 patients with high risk of coronary artery occlusion determined by preoperative CT were enrolled,including 9 patients with tricuspid aortic valve and 3 patients with bicuspid aortic valve.Among the 24 coronary arteries,IVUS was performed on the coronary ostium at the same time as balloon dilation in 3 coronary arteries,and in 11 coronary arteries IVUS was performed after transcatheter heart valve(THV)implantation.Five coronary arteries were determined to be at high risk of occlusion by IVUS examination and coronary stents were implanted.Conclusions IVUS is one of important modality for the risk assessment of coronary artery occlusion during or after TAVR,especially after THV implantation,which can accurately predict the risk of coronary artery occlusion.关键词
