We describe a case of impending paradoxical embolism in a 43-year-old male patient with pulmonary embolism. Transesophageal echocardiography revealed a thromboembolus straddling a patent foramen ovale. The patient underwent emergency removal of the intracardiac clot with closure of the patent foramen ovale. A postoperative work-up for a hypercoagulable state revealed a protein-S deficiency and bilateral lower extremity deep vein thromboses. A Greenfield inferior vena cava filter was inserted, anticoagulation was performed, and warfarin treatment was continued after the patient was discharged home.
