Isolated right ventricular infarction followed by posterior left ventricular infarction after a few days.

This report presents a rare case of isolated right ventricular infarction complicated by bilateral occlusive pulmonary embolism apparently due to right ventricular mural thrombus. Only 2 to 3 weeks later an infarct of the posterior wall of the left ventricle finally occurred. The clinical, pathological and electrocardiographic features of the case are discussed. This case shows that right ventricular infarct can occur without a preceding or simultaneous infarct of the left ventricle.
