Coronary circulation – Wikipedia, Coronary artery dominance – wikidoc, Coronary circulation – Wikipedia, Coronary artery dominance – wikidoc, Coronary arterial dominance is defined by the vessel which gives rise to the posterior descending artery (PDA), which supplies the myocardium of the inferior 1/3 rd of the interventricular septum. Most hearts (80-85%) are right dominant where the PDA is supplied by the RCA.
9/16/2020 · Right coronary artery (RCA) runs in the right part of the atrioventricular (AV) groove and gives off the sinus node artery and right ventricular branches. When it reaches the junction of the interatrial, atrioventricular and interventricular grooves (crux of the heart), it divides into the posterior descending artery (PDA) and posterior left ventricular (PLV) branches.
The dominance of coronary circulation is determined by the type of arteries that supply the posterior and inferior wall of the left ventricle. The artery that supplies the posterior descending artery (PDA) and the posterolateral artery (PLA) determines the coronary dominance. Approximately 60% of the general population are right-dominant, 25% are co-dominant, and 15% are left-dominant.

11/26/2016 · In right and co-dominant hearts, this septum receives blood from the left and right coronary arteries. If the left coronary artery is blocked, collateral circulation can develop via the also-contributing right coronary artery. In left-dominant hearts, this septum receives blood.
The coronary artery system was right dominant in 76%, left dominant in 9.1% and co- dominant in 14.8% of the cases. Ramus intermedius was present in 31%. … Right dominant circulation .
In a right-dominant circulation, the right coronary artery (RCA) supplies the posterior portion of the interventricular septum and gives off the posterior descending artery. This contrasts with a left-dominant circulation, in which the left circumflex (LCX) artery supplies this territory.
