Incorporation of Automated Robotic Transcranial Doppler to Screen for Patent Foramen Ovale and Quantify Right to Left Shunt Severity in the Evaluation of Ischemic Stroke Patients for Stroke Etiology at a Comprehensive Stroke Center (S41.005)

Our study, conducted between December 2021 and October 2022, aimed to assess the effectiveness of automated robotic transcranial Doppler (rTCD) as a diagnostic tool for right-left shunting (RLS) caused by patent foramen ovale (PFO) in stroke patients below 65 years old. Traditional diagnostic methods like transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) have limitations, prompting our exploration of rTCD for more accurate RLS detection.
