Anomalous Course and Branches of Human Coronary Arteries

Abstract

132 hearts obtained from cadavers were dissected in order to study anomalies in the course and branches of human coronary arteries. Only in 1 heart was a deviation of the circumflex branch of the left coronary artery taking a course inferior to the coronary sulcus observed. The right coronary artery travelled the entire length of the coronary sulcus on the back of the heart and gave both a posterior ventricular and a collateral branch. Circumflex branches of the right and left coronary arteries did not anastomose.

Superdominant Right Coronary Artery with Double Posterior Descending Artery

“…[ 1 2 3 4 ] Ilia et al .,[ 5 ] had described a case of superdominant RCA with large tortous right posterolateral ventricular branch to supply the posterolateral nad lateral wall of the heart which is usually supplied by the left circumflex artery. Kumar[ 6 ] had also described anomalous superdominant RCA, which bifurcated into the superior and inferior right circumflex arteries to supply the territory supplied by an absent left circumflex artery. In our case it was double posterior descending arteries arising from a superdominant RCA, which supplied the territories usually supplied by left circumflex artery.…”

Anomalous left anterior descending, absent circumflex and unusual dominant course of right coronary artery: a case report—R1

“…However, the absence of LCx and continuation of RCA beyond crux along the entire length of atrioventricular groove, as was present in our case, is an unusual anomaly. Only few case reports are available in the literature in concern with this type of anomaly [5][6][7].…”
