Where is the posterolateral artery?

Where is the posterolateral artery?

The left ventricular branches of the RCA are known as the posterolateral branches. These branches extend to the adjacent portion of the left ventricle and arise at right angles from the posterior descending artery.

What coronary artery feeds the posterior wall?

The right coronary artery supplies blood to the right ventricle and then supplies the underside (inferior wall) and backside (posterior wall) of the left ventricle.

Is the right coronary artery posterior?

As the right coronary curves posteriorly and descends downward on the posterior surface of the heart, it gives off two to three branches.

Is the left coronary artery posterior?

The posterior descending artery branch supplies blood to the inferior aspect of the heart. The LMCA supplies blood to the left side of the heart. The LAD provides blood to the anterior ventricular septum and the greater portion of the anterior portion of the left ventricle.

What is the posterior descending artery?

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 that is traveling along the anterior surface of the heart.

Where is the posterior descending artery located?

The rest of the right coronary artery and its main branch, the posterior descending artery, together with the branches of the circumflex artery, run across the surface of the heart’s underside, supplying the bottom portion of the left ventricle and back of the septum.

What are the 4 coronary arteries?

The right coronary artery, the left main coronary, the left anterior descending, and the left circumflex artery, are the four major coronary arteries.

What is LAD and LCX?

LAD: left anterior descending artery; LCx: left circumflex artery; LM: left main coronary artery; OM: obtuse marginal; PDA: posterior descending artery; RCA: right coronary artery.

What is posterior descending artery?

Why posterior descending artery is important?

The posterior descending artery is responsible for supplying the posterior third of the interventricular septum, including the posterior and inferior wall of the left ventricle.

What is the LAD artery?

The left anterior descending artery (LAD) is the largest coronary artery runs anterior to the interventricular septum in the anterior interventricular groove, extending from the base of the heart to the apex. The LAD gives two sets of branches.
