Case Report: TAVI in a Patient with Single Coronary Artery and Bicuspid Valve.

A single coronary artery is a rare congenital abnormality which consists of one coronary artery arising from the aortic trunk by a single coronary ostium and providing the perfusion of the entire myocardium. Its prevalence is approximately 0.024-0.066% of the population undergoing coronary angiography. A bicuspid aortic valve is the most common congenital cardiac abnormality and is found in 0.4-2.25% of the population. The coexistence of these two abnormalities together with severe aortic stenosis is extremely rarer. We report a patient who underwent transcatheter aortic valve implantation (TAVI) with a single coronary artery and a bicuspid valve. The procedure was successful, and the patient was discharged home without complication. To the best of our knowledge, this is the first report of these combined abnormalities and TAVI.
