Paradoxical embolism through a patent foramen ovale (PFO) can involve multi
ple organs simultaneously. The most commonly involved sites are the cerebru
m and the extremities. Paradoxical embolism to coronary arteries or upper e
xtremities is relatively uncommon. We report a case of acute pulmonary embo
lism and paradoxical embolism through a patent foramen ovale involving the
left upper extremity, brain, and coronary artery. Early diagnosis in the em
ergency department was made by a trans-esophageal echocardiogram, and the p
atient was successfully treated with intravenous t-PA and heparin, Patients
with acute pulmonary embolism or deep venous thrombosis who also develop s
igns of systemic embolism should be evaluated for a patent foramen ovale, (
