Background Atrial arrhythmias are well-known complications of atrial septal defect (ASD),
and associated with substantial morbidity. After ASD closure, right atrial and ventricular
enlargement regresses, however, the risk of atrial arrhythmia development continues. In this
study, we aimed to investigate the relationship between the Crochetage sign, which is a
possible reflection of heterogeneous ventricular depolarization due to long-term
hemodynamic overload, and the development of late atrial arrhythmia after ASD closure …
