The photokymograph (PKG) is a new noninvasive instrument that can record segmental myocardial wall motion from self-illuminated images such as are produce; by fluoroscopy, cine ventriculography, two-dimensional sonography, and 99mTc scintigraphy. The PKG can be calibrated to provide amplitude of myocardial tissue motion. The recordings of segmental wall motion obtained closely resemble those recorded by established techniques, both during control state and during ischemic episodes. Regression analysis was performed to compare PKG recordings with frame by frame analysis of left ventriculograms (0.98) and with M-mode echo derived from two-dimensional images (r = 0.97). The PKG has some distinct advantages over existing techniques used to analyze segmental wall motion: it is inexpensive, usable simultaneously over multiple areas, analyzes individual beats, and is not restricted to any particular myocardial wall or any particular angle of motion.

Murine models of cardiac disease are becoming an important tool for studying pathophysiological processes. Development of methods to accurately assess ventricular function are therefore important. The purpose of this study was to evaluate the feasibility of echocardiographic assessment of segmental wall motion abnormalities in a murine model of myocardial infarction. Two-dimensional contrast (C+) and noncontrast (C−) echocardiography were performed in 76 awake mice 2 days before and 2 days after left coronary ligation. The short-axis images obtained with two-dimensional echocardiography and corresponding postmortem cross-sectional histological samples stained with Evans blue dye were each divided into 16 segments, and all matched segments were examined for correlation between wall motion abnormalities and myocardial hypoperfusion. With the use of contrast enhancement, the number of visualized segments was significantly increased (base: C− 86%, C+ 98%; midpapillary: C− 57%, C+ 89%; apex: C− 30%, C+ 74%). Agreement between echocardiographically assessed regional wall motion abnormalities and pathologically determined hypoperfusion in basal, midpapillary, and apical levels were 90%, 93%, and 93%, respectively. Agreement between echocardiographically normal wall motion and pathologically normal findings in basal, midpapillary, and apical levels were 99%, 88%, and 71%, respectively. Thus echocardiographic assessment of segmental wall motion in awake mice was feasible and the accuracy was improved with the use of a contrast agent.
