✦ Synopsis
Computer-assisted biplane regional wall motion analysis of left ventriculography has been shown to allow accurate, reproducible identification of normal vs abnormal patients. Recently, however, it has become evident that further quantitation of the degree of regional wall motion abnormality is necessary for optima1 clinical evaluation, particularly in assessing the results of "Intervention Ventriculography". Six commonly utilized methods adapted for ease in desk-top computer analysis were tested on 58 patients with healed myocardial infarctions undergoing biplane left ventriculography. A method utilizing radial chords constructed at 30" intervals from an origin at the centre of the end diastolic long axis proved most successful in both localizing regional wall motion abnormalities and quantifying the degree of abnormality.
