Left coronary ostial stenosis developing 15 months after transcatheter aortic valve replacement with balloon-expandable valve.

ABSTRACT: We present the case of an 82-year-old man whose left coronary ostium became obstructed 15 months after transcatheter aortic valve replacement (TAVR) with a balloon-expandable valve. The patient underwent TAVR for symptomatic severe aortic stenosis with no complications. Fifteen months after the initial TAVR, the patient complained of chest pain while exercising, and the exercise stress myocardial perfusion scintigraphy demonstrated the development of regional myocardial ischemia in the region of the left coronary artery. Coronary angiography implied severe stenosis in the ostium of the left coronary artery. Computed tomography angiography and intravascular ultrasonography indicated a soft tissue component along with stent struts, which was considered to cause delayed coronary obstruction.
