Recurrent paradoxical embolism complicating severe thromboembolic pulmonary hypertension

Abstract

A patient with a three-year history of recurrent pulmonary embolism is presented. Thromboembolic pulmonary hypertension was proven in the final stage of disease in the presence of repeated episodes of systemic embolic events. Paradoxical embolism was assumed to be present on the basis of blood-gas analysis and contrast echocardiography that demonstrated a right-to-left shunt at atrial level. Autopsy revealed a patent foramen ovale and provided strong evidence for the accuracy of the clinical diagnosis.
