A computer model of the left ventricular epicardial surface for quantification of jeopardized myocardium

A computer program has been developed that can be used to quantify the extent of probable myocardial damage which will result from occlusion of a jeopardized coronary vessel. The program, used as an adjunct to coronary arteriography, permits calculation of an area of an arbitrary segment of the left ventricular epicardial surface. This segmental area, when expressed as a fraction of the total LV epicardial area, is a measure of the myocardial mass supplied by a specific coronary arterial vessel. The computer program has been extended to include graphic, three-dimensional simulation of different views of the left ventricular epicardium.
