Introduction. Right ventricular infarction is usually associated with inferior myocardial infarction. This report describes a 63-year-old man who developed refractory hypoxemia in his acute stage of right ventricular infarction, and the presence of right-to-left shunt through a patent foramen ovale was found to result in the hypoxemia. Methods and Results. The unexplained hypoxemia of this patient was found to result from a right-to-left shunt through a patent foramen ovale which was clearly visualized by transesophageal two-dimensional echocardiography; the presence of the intracardiac shunt was detected by color-Doppler study. Cerebral embolic stroke resulting in left homonymous hemianopsia developed in the following days. His cerebral embolic episode was also considered to result from paradoxical embolism through the patent foramen ovale. Conclusion. This report presents an unusual cause of hypoxemia in a patient with right ventricular infarction; the presence of a right-to-left shunt in this condition produce the hypoxemia.
