Abstract:
Although occlusion of the coronary arteries during transcatheter aortic valve replacement is rare, the mortality is high. In this review, we discuss the prevention and management of this complication. Occlusion of coronary ostia is a very rare, but serious, complication of transcatheter aortic valve replacement (TAVR). Although reported as only occurring in <1% of TAVR cases, it carries a high risk of fatality, with some series reporting a mortality rate as high as 40%. We present the management of an occluded left coronary artery after a self-expanding TAVR, and review the incidence, prevention, and management of this complication.
