Clinical Applications Of A Quantitative Analysis Of Regional Left Ventricular Wall Motion

The increasing use of left ventricular cineangiography as a diagnostic and decision-making tool in patients with coronary heart disease has resulted in the definition of certain gross regional abnormalities of wall motion, principally akinesis and paradoxical motion or dyskinesis. These abnormalities have been shown to correlate well with sites of coronary obstructive lesions and with electrocardiographic evidence of myocardial infarction (1,2,3). Such areas of abnormal wall motion may be best displayed by the superimposition of traced left ventricular silhouettes but they are usually obvious on viewing the projected cineangiograms.
