TLDR
The case of a 71-year-old-man, a smoker, admitted for unstable angina, revealed complete proximal occlusion of the left main coronary with an unusual collateral circulation, which shows the importance of looking for atypical collateral circulation in patients with chronic occluded coronary arteries.Abstract:
We report the case of a 71-year-old-man, a smoker, admitted for unstable angina Subsequent investigation revealed complete proximal occlusion of the left main coronary with an unusual collateral circulation The left coronary artery was filled by a large conus branch originating from the right sinus of Valsalva This case shows the importance of looking for atypical collateral circulation in patients with chronic occlusion of the left main coronary artery and normal left ventricular functionread more

Vieussens' arterial ring: a rare coronary variant anatomy.
TL;DR: Although VAR variation is less frequently detected with coronary CT angiography than in previously reported anatomic series, coronary CTAngiography is quite effective to reveal VAR subtypes and other relevant cardiocoronary anomalies.

Angiographic morphology impacts outcomes in STEMI patients with LAD occlusion.
TL;DR: In patients with STEMI because of a proximal LAD lesion treated by primary PCI, the combination of a small conus branch and an occluded first septal perforator branch is associated with a poorer outcome.

Collateral coronary circulation in acute coronary syndrome: sometimes it's enough, sometimes it's not!

TL;DR: A young patient experienced two subsequent acute coronary syndromes due to left anterior descending (LAD) artery occlusion, which underscores the crucial role of the collateral circulation in limiting the effects of acute coronary occlusions.

TL;DR: The clinical importance of the conus branch is emphasized by presenting two cases in which it supplied the distal regions of total occlusion.

TL;DR: In coronary artery disease, the presence of Vieussens' arterial ring (VAR), a ring-shaped anastomosis between the conus branch of the right coronary artery with the left anterior descending artery (LAD), will allow blood flow to return to the obstructed coronary system as mentioned in this paper .

Journal Article
Total occlusion of the left main coronary artery: report of seven cases from 5312 cardiac catheterizations and review of the literature.
TL;DR: The results support previously reported findings about patients with total occlusion of the left main coronary artery in that no definitive clinical pattern leads to simple diagnosis, the anomaly is rarely encountered during cardiac catheterization, and myocardial revascularization alleviates symptoms and prolongs life.
Journal ArticleDOI
Chronic total occlusion of the left main coronary artery.
TL;DR: A patient with angiographic findings of chronic total occlusion of the left main coronary artery with left coronary circulation collateralized from the right coronary artery is described.

TL;DR: In this article, the authors present a case with angiographic documentation of total occlusion of the left main coronary artery in a patient without angina and with a normal rest electrocardiogram in which a syncope was the only symptom.
