Cardiac lymph and lymphatics in normal and infarcted myocardium

Abstract Cardiac lymphangiography was applied to 29 normal dogs (ND) and 14 dogs following acute coronary occlusions. In five of the ND, lymph collected from infarcted dogs was selectively injected into the coronary artery prior to the lymphangiogram. In ND, the lymphatic density (LD) was 6.6% ventricular area (VA). Acute coronary occlusion induced a change in the LD. The infarcted zone registered a decrease in LD (3.6% of VA p
