In the coronary circulation, the posterior descending artery (PDA), also called the posterior interventricular artery (PIV, PIA, or PIVA), is an artery running in the posterior interventricular sulcus to the apex of the heart where it meets with the left anterior descending artery also known as the anterior interventricular artery.

Jan 17, 2024 · A large coronary artery called the posterior interventricular artery, or posterior descending artery (PDA), runs lengthwise along the back of the heart, supplying blood to its posterior (bottom) portion.

Jan 18, 2024 · The posterior interventricular artery (posterior descending artery, PDA) is a branch of the right coronary artery. It is also commonly referred to as the inferior interventricular artery , a more accurate name given that it is not located on the posterior surface of the heart.

Oct 27, 2020 · The inferior interventricular artery (also known as the posterior interventricular artery or posterior descending artery, PDA) is an artery that extends along the inferior interventricular sulcus. The artery supplies the posterior third of the interventricular septum through posterior septal perforating arteries.

The right coronary artery divides into smaller branches, including the right posterior descending artery and the acute marginal artery. Together with the left anterior descending artery, the right coronary artery helps supply blood to the middle or septum of the heart.

Oct 30, 2023 · Around this crux, the right coronary artery can either terminate or give rise to one or two large terminal branches; the inferior interventricular artery (also commonly referred to as the posterior descending artery) and inferolateral branch.

Sep 26, 2022 · The posterior descending artery (PDA) is also known as the posterior interventricular artery because it runs along the posterior interventricular sulcus to the apex of the heart. It is at the apex where it meets the left anterior descending artery traveling along the heart's anterior surface.

Mar 1, 2020 · Posterior wall myocardial infarction occurs when circulation becomes disrupted to the posterior heart. It commonly cooccurs with inferior or inferolateral MI, but when in isolation, posterior myocardial infarction represents a diagnostic challenge.

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.

This aberrant vessel passed anterior to the root of the main pulmonary artery and the right ventricle to reach the acute margin of the heart before passing onto the inferior surface and terminating as the main posterior descending artery (PDA).
