Acute coronary artery occlusion is a rare but devastating complication of transcatheter aortic valve replacement. Coronary obstruction is angiographic evidence of a new-partial or complete-obstruction of a coronary artery. Key factors identifying patients at risk are aortic root anatomy, type of aortic valve, and type of transcatheter heart valve. Techniques to prevent coronary obstruction include intentional leaflet laceration. If acute coronary obstruction does occur, bailout stenting can be challenging and conversion to emergent open heart surgery may be required, both of which are associated with high morbidity and mortality.
