Thrombus Inside the Channel of Patent Foramen Ovale Revealed by Optical Coherence Tomography Imaging in a Patient with Myocardial Infarction—Case Report

Abstract

Myocardial infarction (MI) caused by patent foramen ovale (PFO)-based paradoxical embolism is rare, and there are few case reports in the literature. Here, we report a case of MI in which optical coherence tomography revealed in situ thrombi in the PFO channel. In addition to paradoxical embolism, in situ thrombus may also be one of the pathogenic mechanisms of PFO in patients with MI.
