Abstract
Abstract Infarcts of the posterolateral wall of the left ventricle were produced in 73 swine by gradual occlusion of the left circumflex artery. Hg 203 -chlormerodrin was injected intravenously into 33 survivors 12 to 14 hours before sacrifice. Photoscanning of intact and "unrolled" hearts showed a hot area of selective uptake of the isotope in the area of the infarct, which correlated well in location and extent with pathologic observations. Intensity of selective uptake varied inversely with the length of time after application of the constrictor. Photoscanning of selective uptake of Hg 203 -chlormerodrin is a valuable method for demonstrating areas of myocardial infarcts before replacement by fibroblastic tissue.
