A Rare Complication after TAVI: Acute Left Main Coronary Artery Occlusion and Successful Percutaneous Treatment

Aortic valve stenosis (AS) is common in the elderly. Nowadays surgical aortic valve replacement still has been the gold standard of management, but many patients have been excluded from surgery given that they were very old, frail, or had co-morbidities that increased operative risks. In the last decade, transcatheter aortic valve implantation (TAVI) has emerged as a new treatment option for these patients. Despite being less invasive than surgery, TAVI has rare but fatal complications like vascular injuries. Vascular injuries are the most common complications after TAVI, and range from dissection, to perforation, to acute thrombotic occlusion. We report a case of left main coronary artery (LMCA) occlusion following TAVI that caused cardiac arrest and was managed successfully with emergency percutaneous coronary intervention (PCI).
