What does Ramus mean in cardiology?
The ramus intermedius (RI) is a variant coronary artery resulting from bifurcation of the left main coronary artery (LMCA) [1]. Generally, it is diagnosed on autopsy [2]. Recently, RI has increasingly been observed by computed tomography angiography (CTA) of the coronary artery [3,4,5].
Can Ramus artery be stented?
Although the ramus was only 40% narrowed in diameter, it contained intraluminal clots, and its two major branches were occluded, presumably from embolized clot. The occluded branches of the ramus intermedius were not deemed suitable for angioplasty/stenting.
Where is the Ramus intermedius coronary artery?
If an artery arises from the left main coronary artery between the left anterior descending artery (LAD) and the left circumflex artery (LCX), it is known as the ramus intermedius.
Where is the Ramus vessel?
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.
