Rapid Spontaneous Coronary Artery Reperfusion Following Severe Bradycardia During Exercise Tolerance Test: A Rare Case Report

The acute occlusion of a coronary artery without the evidence of myocardial infarction might immediately affect both the diagnosis and treatment of coronary artery disease. We present the case with a sudden occlusion of the left main coronary artery without typical chest pain following an exercise tolerance test and rapid spontaneous reperfusion of the left main coronary artery.

Association 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:...

A later stage of anomalous coronary circulation with origin of the left coronary artery from the pulmonary artery. Coronary artery steal.

Coronary collateral growth and its therapeutic application to coronary artery disease.

There is a tremendous body of data concerning the coronary collateral circulation in both experimental animals and humans. The functional importance of a well-developed coronary collateral circulation has now been documented. The paradigm regarding the principal stimulus for coronary collateral growth has shifted from myocardial ischemia to increased shear stress at the site of pre-existing col...

Circulating Coronary Blood Volume.

• The development of catheterization and indicator dilution techniques has made it possible to measure the volume of circulating blood within many organs in the intact animal. Hirche and Lochner injected measured amounts of dye into the coronary arteries of dogs and recorded the subsequent time course of dye concentration in blood from the coronary sinus. From this single curve both coronary bl...

Analysis of the influence of heart size and gender on coronary circulation type.

Currently, there are many types of classification of coronary circulation. The first type was introduced in 1904 by Banchi. Hettler provides very detailed criteria for the type classification based on the course of the anterior and posterior interventricular branches. Hettler defined the following types: left coronary artery dominance, right coronary artery dominance, and co-dominant. The objec...
