Collateral circulation from the conus coronary artery to the anterior descending coronary artery: assessment using multislice coronary computed tomography.
The prognosis of patients with coronary artery disease largely depends on the presence of a collateral circulation. The location and extent of the collateral circulation is highly variable and these parameters determine whether or not ischemic symptoms occur and whether left ventricular contractility is abnormal. The collateral circulation is generally established through small-caliber distal v...
متن کاملFrequency and clinical significance of failure to visualize the conus artery during coronary arteriography.
In patients with occlusion of the left anterior descending coronary artery (LAD) or right coronary artery (RCA), the conus artery, which arises at or near the origin of the RCA, often serves as a principal source of collateral circulation. Coronary arteriograms in 508 adult patients revealed that in 80.5% the conus artery was well visualized on the RCA angiogram, but that in 19.5% it was not ad...
متن کاملImaging the periphery of an occluded left anterior descending coronary artery: need for selective conus artery catheterisation.
A 56-year-old man, a current smoker with a history of arterial hypertension and dyslipidaemia, was admitted to our department for a scheduled coronary angiography. Ten days earlier, the patient had been admitted to another hospital for an anterior myocardial infarction, treated with intravenous thrombolysis. The patient’s in-hospital course was reported to have been complicated by an episode of...
متن کاملAssociation Between Left Anterior Descending Artery Length with Coronary Artery Dominance: An Angiographic Study
Introduction: Although left anterior descending (LAD) artery supplies a large portion of the myocardium, the amount of blood supply provided by LAD is depended on the length of the LAD. The aim of the current study was to evaluate the association between coronary artery dominance and LAD anatomic types in patients with normal epicardial coronary arteries. Methods:...
متن کاملLeft anterior descending coronary artery obstruction. Clinical, electrocardiographic, and angiographic correlates.
Seventy-six patients with severe (greater than 80%) occlusive left anterior descending coronary artery disease by coronary angiography were examined for the electrocardiographic characteristics of this disease in the presence (group A 59 patients) or the absence (group B 17 patients) of anterior wall asynergy (akinesis or dyskinesis). The incidence of clinically documented anterior myocardial i...
