Abstract:
:To determine the effect of an anteroseptal myocardial infarction on right ventricular systolic and diastolic function, we studied 12 pigs before and 1 h after left anterior descending coronary artery occlusion. Total arterial occlusion was achieved by the percutaneous, transcatheter placement of a 1 mm Teflon plug into the mid portion of the artery. The resulting infarction involved 28 (SEM 3)% of the left ventricular wall, in the anterior and septal regions. A small rim of the right ventricular free wall adjacent to the septum and the right ventricular apex were also affected. End diastolic pressures in both ventricles rose significantly: left ventricular from 12(1) to 20(2) mm Hg and right ventricular from 8(1) to 10(1) mm Hg. Right ventricular peak systolic pressure increased from 29(2) to 35(2) mm Hg while left ventricular peak systolic pressure did not change. One hour after infarction the half time of isovolumic relaxation of the right ventricle was prolonged from 6.9(0.5) to 8.7(0.4) ms. Ejection fraction in both ventricles was depressed: from 46(1) to 34(2)% in the right ventricle and from 69(3) to 49(3) in the left ventricle. There was no change in either right or left ventricular dP/dt. These data suggest that right ventricular systolic and diastolic dysfunction occurs as the result of an anteroseptal myocardial infarction in pigs.
