Abstract:
We report a 63 year-old female with a pulmonary embolism in whom echocardiography revealed the presence of right heart thrombus. A section of this thrombus was entrapped in a patent foramen oval and floating in both atria. This rare situation, named impending paradoxical embolism, prompted us to perform a surgical intervention, removing the thrombus and repairing the foramen ovale.
