12-lead electrocardiography-based scoringsystem for predicting the probability of atrial septal defect closure in adults with pulmonary hypertension.
BACKGROUND Assessing atrial septal defect (ASD) operability in patients with pulmonary hypertension (PH) is challenging in resource-limited settings due to restricted access to right heart catheterization (RHC). This study aims to develop and validate a 12‑lead electrocardiography (ECG)-based scoring system to predict...
