Question: What does the Ramus artery do?

The ramus intermedius artery will supply a lateral wall territory between the first diagonal and the first obtuse marginal branch territories. Rarely, the left main coronary artery will be absent and the LAD and circumflex artery will arise directly from the aorta.

Does everyone have a Ramus artery?

Dr Yuranga Weerakkody ◉ and Dr Henry Knipe ◉ ◈ et al. The ramus intermedius is a variant coronary artery resulting from trifurcation of the left main coronary artery 1. It is present in ~20% (range 15-30%) 2-3 of the population.

What is the Ramus of the heart?

Sometimes, an additional artery arises at the bifurcation of the left main artery, forming a trifurcation; this extra artery is called the ramus or intermediate artery.

Where is the Ramus?

Two vertical portions (rami) form movable hinge joints on either side of the head, articulating with the glenoid cavity of the temporal bone of the skull. The rami also provide attachment for muscles important in chewing.

Which artery is called the Widowmaker?

The widow-maker is a massive heart attack that occurs when the left anterior descending artery (LAD) is totally or almost completely blocked. The critical blockage in the artery stops, usually a blood clot, stops all the blood flow to the left side of the heart, causing the heart to stop beating normally.

Which coronary artery is most commonly blocked?

Importance in cardiovascular diseases:

The LAD artery is the most commonly occluded of the coronary arteries. It provides the major blood supply to the interventricular septum, and thus bundle branches of the conducting system.

Where is the Ramus artery on the heart?

It generally goes in the angle between the LAD and the LCX.It may either behave like a large OM or a diagonal branch.It supplies the lateral free wall of the LV many times. The peculiarity of this vessel is it does not run in a anatomical groove .

What percent of blockage requires a stent?

By clinical guidelines, an artery should be clogged at least 70 percent before a stent should be placed, Resar said. “A 50 percent blockage doesn’t need to be stented,” he said.

What is the Ramus coronary artery?

The ramus intermedius artery will supply a lateral wall territory between the first diagonal and the first obtuse marginal branch territories. Rarely, the left main coronary artery will be absent and the LAD and circumflex artery will arise directly from the aorta.
