Echocardiographic diagnosis of a giant thrombus passing through a patent foramen ovale from right atrium to the left atrium

Abstract

Pulmonary embolus sourced by right atrial thrombus trapped in a patent foramen ovale is an unusual, rare condition. Thus in suspicion of massive pulmonary thromboembolus, echocardiographic examination carries great importance evaluate right ventricular functions and diagnose right sided intracardiac thrombus. We report a 76-year-old female with massive pulmonary embolism caused by a gigantic thrombus trapped in a patent foramen ovale. The echocardiography was the diagnostic procedure to display the source of the thromboembolism and urgent cardiac surgery was successful and life-saving treatment in this case.
