Abstract
It is generally accepted that the determination of regional ventricular performance is more informative than the study of overall hemodynamic parameters during myocardial ischemia. Measurements of changes in segment length during coronary artery occlusion have provided valuable information about the contractile state of ischemic myocardial segments [1–3]. Sasayama et al. [3] also demonstrated that changes in myocardial wall thickness are inversely related to changes of segment length but the measurement of myocardial wall thickness has been hampered by numerous technical problems [4–6]. The introduction of small ultrasound transducers which can be sutured on the epicardium has recently stimulated the study of wall thickness [7—8]. Analysis of wall thickness has generally been limited to the determination of wall thickness at both end-diastole and end-systole and little attention has been paid to the time course and velocity of wall thickness changes throughout the cardiac cycle.
