Congenitally corrected transposition of the great arteries (ccTGA) or double discordance is a rare congenital heart defect associating disco b Derived transmitral (black line), pulmonary venous (gray line), and coronary sinus (light gray line) average velocity vs. time courses. Although PLSVC is infrequent among all vascular anomalies, it is the most common thoracic venous anomaly. The left coronary artery has a proportionally very large diameter, approximately 1:2 when compared to that of the aorta, and this ratio in human would be much closer to 1:10 (Figure 9f). His left ventricular function was estimated to be 20% (normal generally > 50%) and an intra-aortic balloon pump was inserted to maintain his blood pressure. The right and left coronary arteries are the first to branch off the aorta and arise from two of the three sinuses located near the base of the aorta and are generally located in the sulci.
