Evaluation of Blood Flow Velocity Waveforms in Intramyocardial Artery and Vein by Laser Doppler Velocimeter with an Optical Fiber

  • Chapter
Microcirculation in Circulatory Disorders

Abstract

It is well established that the part of the left ventricle at greatest risk to ischemia is the subendocardium. Both in myocardial infarction in humans and experimental myocardial infarction in dogs, the subendocardial muscle shows the most extensive necrosis and the subepicardium is spared. Thus, it is important to evaluate phasic blood flow in deeper intramyocardial layers. Measurements, however, have been restricted in the region of epimyocardium because of the methodological limitations [1–3].
