Determinants of arrhythmic death due to coronary spasm: effect of preexisting coronary artery stenosis on the incidence of reperfusion arrhythmia.

Coronary spasm can occur in the presence or absence of coronary artery disease. We therefore determined the effect of preexisting coronary stenosis on the incidence of ventricular fibrillation during reperfusion after circumflex artery (CFX) occlusion. Twenty dogs underwent a 30-minute open-chest CFX occlusion. During reperfusion, CFX blood flow was restricted by a partial occluder. In dogs tha...

Coronary Artery Spasm is a Nightmare: a Rare Case of Multi Vessel Coronary Artery Spasm

Coronary artery spasm is not an uncommon event, but its pathophysiologic mechanisms followed by coronary artery vasospasm are not yet completely clarified. Coronary artery spasm can lead to sudden cardiac death due to ventricular arrhythmias or heart block. In the cases of cardiogenic shock secondly to severe coronary artery spasm, IABP is sufficient to support the patient’s hemodynamics, in th...

Multiple myocardial bridge in a 59 year-old woman

Introduction: Myocardial bridging is a congenital condition in which a segment of a major epicardial coronary artery has an intra myocardial route. Myocardial bridging is usually confined to a single vessel and is typically the mid segment of the left anterior descending artery. Bridging may be associated with chest pain, myocardial infarction, and sudden cardiac death, or usually asymptomati...

Coronary Artery Spasm During Dobutamine Stress Echocardiography: A Case Report

Dobutamine stress echocardiography (DSE) has been widely used as a diagnostic and prognostic modality in the management of stress. DSE is associated with limited complications and adverse effects on the health of patients. In this case report, we described a 42-year-old female patient with dobutamine-induced coronary artery spasm with history of exertional dyspnea, which had deteriorated recent...

Myocardia ischemia associated 1 with a myocardial bridge with no significant atherosclerotic stenosis

25 Myocardial bridge refers to the myocardial tissue with which the coronary artery is 26 partly covered. Though it has long been regarded to be benign, patients with 27 myocardial bridges may present with myocardial ischemia, acute coronary syndromes, 28 coronary spasm, sudden cardiac arrest or even sudden death. In present study, we 29 reviewed four cases with myocardial bridge and no stenosi...
