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.

background: small side branches, albeit less important than their larger counterparts, have not yet received due attention in the literature. nor has there ever been a comparison between drug-eluting stents and bare metal stents apropos side branch occlusion . the aim of this study was to compare the patency of small (≥0.5 and ≤1.5 mm in diameter) side branches with respect to bare metal vs. dr...

we report a rare case of acute right coronary artery stenosis developing in a patient undergoing aortic valve replacement. we present a case report with a brief overview of the literature relating to coronary artery occlusion associated with cardiac valve surgery – the theories and treatments are discussed. a 85 year-old female was admitted under the care of the  cardiothoracic team with signs ...

PURPOSE Myocardial infarction in children with total occlusion of a coronary artery after Kawasaki disease is rare due to multiple collateral vessels. We aimed to investigate the changes in coronary perfusion associated with coronary artery occlusion after Kawasaki disease. MATERIALS AND METHODS Eleven patients with coronary artery occlusion after Kawasaki disease were investigated. Serial co...

repetitive episodes of brief regional ischemia have been shown to reduce the severity of life-threatening ventricular anhythrnias and infarct size that occur during prolonged occlusion of the coronary artery. this phenomenon is known as ischemic preconditioning. during studies in anesthetized, open chest wistar rats, we accidentally observed that poorly ventilated animals had a reduced severity...

We studied the effect of cardiopulmonary bypass, transient acute coronary occlusion (2-5 minutes), prolonged coronary occlusion (> 60 minutes), and coronary reperfusion on the left ventricular diastolic pressure-volume curve, using an isovolumic working canine heart preparation in which heart rate, intraventricular volume, and aortic pressure were controlled. Cardiopulmonary bypass caused no si...

Coronary sinus occlusion retards necrosis of ischemic myocardium. To test the hypothesis that coronary sinus occlusion induces retrograde venoarterial flow, the coronary arteriovenous pressure gradient and the coronary arterial oxygen saturation were measured distal to a left anterior descending coronary artery ligature in dogs. In parallel, we constructed a mathematical model of known coronary...

Seven dogs were instrumented with a left ventricular micromanometer, pairs of ultrasonic crystals to measure wall thickness in normal and ischemic regions, as well as both short and long axes of the left ventricle; and cuff occluders were placed around the left circumflex coronary artery and the inferior vena cava. Left ventricular volume, mass, circumferential wall stress, midwall strain, and ...
