Transcatheter aortic valve implantation (TAVI) is one of the rapidly evolving treatment strategies for severe aortic stenosis. Included in this category are inoperable, high, intermediate, and low surgical risk patients. It has varying types of complications that may require urgent surgical or transcatheter interventions to prevent procedural mortality and morbidity. Coronary artery occlusion is a rare and dreaded complication of TAVI. Here, we report a 73-year-old man who was diagnosed with severe aortic stenosis and underwent transfemoral TAVI. Unfortunately, during preimplantation balloon valvuloplasty, the patient developed severe hypotension along with ischemic changes on the electrocardiographic monitor. Promptly, coronary angiography was performed which revealed complete occlusion of the left anterior descending artery secondary to embolic debris. He was successfully rescued by manual aspiration thrombectomy (MAT). MAT results in restoration of coronary flow and reversal of shock condition before completing TAVI procedure.
