摘要：Recently, the utilization of transcatheter aorticvalve implantation (TAVI) has gained incr-easing prevalence due to its expanding ran-ge of applications in managing symptomatic severe ao-rtic stenosis (AS). Coronary obstruction, a life-threaten-ing complication, has been reported to occur during and after TAVI at an incidence rate of 0.5％-1％.[1] In additi-on to shallow sinus of Valsalva (less than 30 mm), low co-ronary take-off (below 12 mm from annulus plane), and calcification of native valve leaflets over the coronary os-tium, anomalous origins of coronary arteries and com-pression from expanded transcatheter heart valve have been shown to cause TAVI-associated coronary occlu-sion.[2,3] To successfully perform this procedure, careful consideration of the anatomical characteristics of the co-ronary arteries is crucial, particularly the coronary hei-ght and sinus depth, as well as the spatial relationship between the coronary artery and the implanted valve. Despite the increasing number of TAVI procedures be-ing performed, scarcity of reports exists on TAVI proce-dures performed in patients with anomalous coronary arteries. This report describes a case study of an AS pat-ient with an anomalous right coronary artery originating from the left coronary sinus with an interarterial course, who underwent a successful TAVI procedure.
