Abstract:
Transcatheter aortic valve replacement (TAVR) is widely performed in patients with severe aortic stenosis (AS), having a high surgical risk. However, reports of TAVR performed in patients with anomalous coronary arteries are rare. In existing literature, several complications including coronary obstruction are reported. In this study, we report a 77-year-old female patient with severe AS and anomalous origin of the left coronary artery from the right coronary sinus, who successfully underwent TAVR. <Learning objective: During transcatheter aortic valve replacement in patients with anomalous coronary arteries, special attention might be given to the topographical location of the coronary artery from the aortic root and the implanted valve for preventing a coronary obstruction.>.

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...
