2019年11月16日 · What is the ramus coronary artery? The third artery: Normally the main coronary blood vessel has two branches--the left anterior descending artery and left circumflex, but some people have a third branch termed intermediate artery or ramus-coronary artery--see picture. The incidence is some where between 10-30%.
What is the clinical significance of ramus intermedius coronary …
2008年12月16日 · What would be the ECG finding if a large ramus is the culpirit vessel during STEMI ? This scenario could be rare. ACS in ramus could present as ST elevation in 1/Avl /V5,V6. Lateral MI; Apical MI; High lateral MI; But it is realised , whenever the ECG changes are not fitting with typical ASMI or a lateral MI one should suspect a ramus lesion
The Ramus Intermedius: A Bridge to Survival in the Setting of …
The presence of RI has advantages and disadvantages from a theoretical perspective. Specifically, a large-diameter RI can provide an additional collateral supply of blood to the LV anterolateral wall in cases of compromised coronary circulation.
Coronary artery anomalies overview: The normal and the abnormal
Coronary angiography demonstrated three large coronary arteries without any significant stenotic lesion. An additional duplicated LCX was found originating from the RCA. A 90% stenosis was found at the ostium of this aberrant vessel. Moreover, several small coronary artero-venous fistulae were found to arise from a large diagonal branch (Figure ...

2023年7月29日 · 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. It can have a course similar to the obtuse marginal branches of the left circumflex artery or the diagonal branches of the left anterior descending artery and thus can ...
Impact of ramus coronary artery on computed tomography …
A large ramus was associated with a higher prevalence of a distal FFR CT ≤.80 (odds ratio 7.0, 95% CI 1.2-40.1, p = .03). A proximal ramus diameter predicted distal FFR CT ≤.80 (cut-off 2.1 mm, AUC .76, sensitivity 100%, specificity 52%, 95% CI .61-.90).
Concomitant coronary microvascular dysfunction and …
2021年7月22日 · However, a large ramus branch had tubular narrowing consistent with type 3 SCAD (Online Video 1). She was treated for non-ST segment elevation myocardial infarction (NSTEMI) with dual anti-platelet therapy and intravenous heparin and was discharged on aspirin, ticagrelor, lisinopril, and metoprolol.
Effect of Presence of Ramus Intermedius Artery on Location of …
In their work, Galbraith et al., found that the presence of Ramus Intermedius (RI) was associated with more proximal left anterior descending coronary artery (LAD) lesions and hence larger anterior infarctions.
Ramus intermedius - wikidoc
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. The ramus intermedius occurs in 37% of the general population, and is considered a normal variant.
An Unusual Course of the Ramus Intermedius - PMC - National …
The ramus intermedius (RI) rose early from the LMCA, gave rise to some conal branches and a major septal branch, and passed intraseptally between the aorta and the outflow tract of the right ventricle, where it narrowed during each systole. The RI crossed under the middle LAD and emerged epicardially to reach the free lateral wall.
