Hemodynamic pattern resembling pericardial constriction after acute inferior myocardial infarction with right ventricular infarction.
Two patients with acute inferior myocardial infarction complicated by cardiogenic shock are presented. Cardiac catheterization 2 and 7 days after infarction, respectively, revealed a hemodynamic pattern resembling constrictive pericarditis. Right coronary occlusion proximal to the right ventricular marginal branches was present in both patients. Resolution of the constrictive hemodynamic pattern was demonstrated in the one survivor at repeat catheterization 7 weeks after infarction. The mechanism for constrictive hemodynamics in these patients is unclear.
