A female patient, 56, with mitral heart disease and chronic atrial fibrilation is presented. She underwent mitral valve replacement with bioprosthesis twice previously. Suffering from hypercholesterolemia and not in anticoagulant therapy, she was admitted in the emergency room with clinical history and electrocardiogram of a posterior infarction. Diagnosis was later assured by serum CK-MB and coronary arteriography. The electrovectocardiographic aspects of the case agree with those reported in the literature.
