title: The assessment of regional abnormalities of the left ventricle by angiography.
abstract: A method of regional wall motion analysis of left ventricular cineangiograms which does not make assumptions about ventricular geometry is described. The technique measures the movement of the ventricular perimeter in relation to the geometric center of gravity of the endsystolic frame expressing movement as a change in radical length. 10 control patinets each with 3 left ventricular cineangiograms, comprise the group for definition of normal values of movement and permit estimations of reproducibility within and across patient groups. Isolated examples of abnormal wall motion are shown.
