Electrocardiographic Predictors of High-Risk Patent Foramen Ovale Anatomy Defined by Transesophageal Echocardiography.

ABSTRACT: Background: Patent foramen ovale (PFO) is a common finding linked to cryptogenic stroke. Transesophageal echocardiography identifies high-risk anatomical features, but it remains unknown whether electrocardiography (ECG) may distinguish between high-risk and low-risk PFO anatomies. Methods: This retrospective single-center study included 207 consecutive patients (median age 45 years; 46.9% male) who underwent percutaneous PFO closure between January 2021 and June 2025. Patients were stratified into low-risk (score 0-1, n = 46), and high-risk (score 2-5, n = 161) groups using the Nakayama risk score. Baseline 12-lead ECGs were analyzed for crochetage R wave, right bundle branch block, RSR' pattern, and T-wave abnormalities. Clinical, laboratory, and echocardiogra
