Sep 6, 2024 · Most hearts are right dominant, in which the PDA is supplied by the RCA. However up to 20% of hearts may be left dominant, in which the PDA is supplied by the LAD or LCx or codominant, whereby a single or duplicated PDA is supplied …

Jul 13, 2016 · The PDA and PL branches supply the inferior wall of the left ventricle and AV node. Proximal LAD: from the orifice halfway to acute margin. Middle LAD: remained halfway to acute margin.

It is typically a branch of the right coronary artery (70%, known as right dominance). Alternately, the PDA can be a branch of the circumflex coronary artery (10%, known as left dominance) which itself is a branch of the left coronary artery.

Oct 14, 2008 · In 65% of cases the posterior descending artery (PDA) is a branch of the RCA (right dominant circulation). The PDA supplies the inferior wall of the left ventricle and inferior part of the septum.

Aug 14, 2014 · RCA: right coronary artery; PDA: posterior descending coronary artery. PLV: posterior left ventricular branch, also known as PLB. Right coronary angiogram showing stenosis of RCA and PDA. RCA shows two lesions, one in the proximal region and another distally just before the crux where PDA and PLV branches originate (pre-crux stenosis of RCA).

Mar 16, 2021 · The PDA and posterolateral (PL) branches that supply the inferior ventricular septum and the inferior wall, respectively, can originate from only the RCA (right dominant, 65–90%), from only the LCx artery (left dominant), or from both arteries (codominant).

Jan 23, 2021 · The posterior left ventricular (PLV) artery, also known as the posterolateral artery or branch (PLA or PLB), is a terminal branch of the coronary arterial system supplying the inferior portion of the heart.

Sep 16, 2020 · PDA and PLV branches arise from the LCx in a left dominant system. In a co-dominant system, PLV comes from the LCx and PDA from the RCA. The atrioventricular nodal (AV node) artery usually arises from the right coronary artery. The LAD can be three types depending on its distribution:

An additional branch of the RCA that is more lateral and closer to the circumflex is the posterolateral (PL) branch. "Dominance" is determined by the artery (either right coronary artery or left circumflex artery) that supplies the PDA.

Sep 17, 2016 · Atrioventricular nodal artery usually originates near the bifurcation of the right coronary artery into PDA and PLV. Right coronary angiogram is usually obtained using a Judkins right curve catheter while approaching from the femoral arterial route.
