Insights
This case report details a rare congenital heart defect involving a single coronary artery and a bicuspid aortic valve. Transcatheter aortic valve implantation (TAVI) was successfully performed on a patient with these combined conditions.
Area of Science:
- Cardiology
- Congenital Heart Disease
- Interventional Cardiology
Background:
- A single coronary artery is a rare congenital anomaly affecting 0.024-0.066% of individuals.
- A bicuspid aortic valve is the most common congenital heart defect, present in 0.4-2.25% of the population.
- The simultaneous occurrence of a single coronary artery, bicuspid aortic valve, and severe aortic stenosis is exceptionally rare.
Abstract:
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.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
