摘      要：Recently,the utilization of transcatheter aortic valve implantation(TAVI)has gained increasing prevalence due to its expanding range of applications in managing symptomatic severe aortic stenosis(AS).Coronary obstruction,a life-threatening complication,has been reported to occur during and after TAVI at an incidence rate of 0.5%-1%.^([1])In addition to shallow sinus of Valsalva(less than 30 mm),low coronary take-off(below 12 mm from annulus plane),and calcification of native valve leaflets over the coronary ostium,anomalous origins of coronary arteries and compression from expanded transcatheter heart valve have been shown to cause TAVI-associated coronary occlusion.
