Intracardiac entrapped and pulmonary embolism developing during oral contraceptive therapy in a young woman.

We report a case of biatrial thrombus entrapped in a patent foramen ovale (PFO) in a 39-year-old woman under oral contraceptive therapy who was admitted to our hospital with multiple pulmonary embolism without paradoxical embolism. We present this case because of the relatively unusual thromboembolic disease.
