Although coronary arterial lesions can be precisely defined by angiographic techniques, their functional significance remains difficult to determine. To evaluate the physiologic consequence resulting from diseased coronary arteries, regional myocardial performance was assessed from the biplane coronary cineangiograms in 11 patients. Opacified coronary bifurcations were used as epicardial landmarks. By following the spatial distance between bifurcations, multiple epicardial segment lengths and their dynamic changes during a cardiac cycle were determined. Various studies of regional myocardial performance, including the onset, magnitude, and velocity of segment shortening, were quantitated and compared in multiple and selected areas of the heart.
