In subjects with coronary heart disease, the ventriculogram provides important data about the size, shape, and ejection pattern of the left ventricle. Studies of the motion of individual segments of the myocardium can provide information about local disturbances in contraction (asynergy), as well as information about the residual contractile pattern of normal zones of the ventricle. Approximately 35% of patients referred for the assessment of clinical coronary artery disease show a normal ventricular contraction pattern at rest. The remaining 65% will demonstrate some typle of resting left ventricular asynergy. Prior studies have reported that these abnormalities are most commonly seen in patients with previous myocardial infarction, but asynergy can also occur without evidence of infarction. The patterns may range from the classic well-demarcated bulging left ventricular aneurysm to various types and degrees of contour. Asynergic segments may be dyskinetic, akinetic, or hypokinetic, and the area may be composed of muscle or scar or both. A disturbed temporal sequence of contraction (asynchrony) may also be observed.
