Right ventricular subendocardial infarction in a patient with pulmonary hypertension, right ventricular hypertrophy, and normal coronary arteries

Abstract

Right ventricular infarction is usually associated with coronary artery disease and concomitant left ventricular infarction. Isolated right ventricular subendocardial necrosis was discovered at autopsy in a 52-year-old woman with pulmonary hypertension, right ventricular hypertrophy, and normal coronary arteries, who died with septicemia 41 days after mitral valve replacement. This represents the first well-documented report of isolated right ventricular subendocardial infarction associated with normal coronary arteries.
