Right Atrial Septal In Situ Microthrombus: A Potential Novel Cause of Patent Foramen Ovale-Associated Stroke.

ABSTRACT:

Background

Patent foramen ovale (PFO)-associated stroke has a complex and diverse pathogenesis. It mainly results from a paradoxical embolism caused by venous thrombosis. However, few studies have investigated the presence of an in situ thrombus in the right atrium. Transesophageal echocardiography can effectively detect right atrial septal in situ microthrombus. Therefore, we aimed to explore the relationship between a right atrial septal in situ microthrombus and PFO-associated stroke and further dissect the pathophysiological basis of microthrombus formation.

Methods and results

Between April 2022 and October 2023, we prospectively investigated 466 patients who visited our hospital for transesophageal echocardiography with a high clinical suspicion of PFO. Right atrial se
