The patient underwent emergency intervention for the circumflex branch, but it was still difficult to implant a stent.
The abnormal RCA had multiple collaterals from the LAD and left circumflex branch (Figures 3 and 4).
The angiogram of the right coronary artery with the right posterolateral branch giving collateral flow to the atrioventricular circumflex branch is the second most common collateral pattern for circumflex CTOs [10]; however, the turn taken by the A-V circumflex vessel is not the usual course.
In most of the cases it is a branch of right coronary artery (RCA), but in 35% cases it may arise from circumflex branch of left coronary artery (LCA).
Other factors associated with TLR were minimal stent diameter (HR (per 1mm increase)--0.43 [95% CI 0.26-0.7, p = 0.0008]), stent length (HR (per 3 mm increase)--1.08 [95% CI 1.03-1.13, p = 0.003]), and lesions localized in the circumflex branch of the left coronary artery (reference LAD) (HR--0.49 [95% CI 0.24-0.99, p = 0.04]) (Figure 4).
Angiography revealed marginal changes in the coronary arteries, with a muscular bridge causing 30-50% stenosis in the middle of the circumflex branch of the left coronary artery (Photo 1).
Results: The incidence of plaques (P less than 0.05) the proportion of plaques in the circumflex branch (P less than 0.05) the proportion of medium-severe lumen stenosis induced by plaques (P less than 0.05) and the proportion of obstructive plaque involved multi-branch (P less than 0.05) of the Mongolian patients were higher.
After origin, it was divided into anterior interventricular and left circumflex branch at a distance of 20 mm and continued in its normal course.
Just four weeks later, in June 1992, symptoms again returned and an exam showed total occlusion of the right coronary artery, 100 percent blockage in the circumflex branch, and partial blockage in the left anterior descending branch of the left coronary artery.
* BACKGROUND Differentiating occlusion of the circumflex branch of the left coronary artery (also called the circumflex artery) from occlusion of the right coronary artery is often difficult because either may be associated with a pattern of acute inferior myocardial infarction on the electrocardiogram.
