In many cases, particularly in a right-dominant … In the other 15% of cases (Left Dominant), the PDA is given off by the left circumflex artery. The artery runs downward through the right atrioventricular groove that separates the right atrium and right ventricle, before curving towards the back. The circumflex artery, fully titled as the circumflex branch of the left coronary artery, is an artery that branches off from the left coronary artery to supply portions of the heart with oxygenated blood. 3.

The right coronary artery branches into: Right marginal artery Posterior descending artery We present a very unusual case of an anomalous origin of the left circumflex coronary artery (LCx) from the proximal right coronary artery (RCA). It travels down the right coronary sulcus, towards the crux of the heart. In the other 85% of all cases the posterior interventricular artery comes out of the right coronary artery. The terminal branch is usually the largest of these branches. Arising at the aorta, the right coronary artery and its branches are major sources of blood to the right ventricle and atrium of the heart. We report two cases of rare left circumflex artery (LCX) anomalies: one case of absent LCX with super-dominant right coronary artery (RCA) and another of anomalous origin of LCX from right coronary sinus. #2.
