The case report presented in this edition by Mu . The report presents a case of atrial septal defect (ASD) associated with electrocardiographic changes, noting that the crochetage sign resolved after Selective His Bundle Pacing (S-HBP) without requiring surgical closure. The mechanisms behind the appearance and resolution of the crochetage sign remain unclear.

Background: Crochetage sign is a specific electrocardiographic manifestation of ostium secundum atrial septal defects (ASDs), which is associated with the severity of the left-to-right shunt. Herein, we reported a case of selective his bundle pacing (S-HBP) that eliminated crochetage sign in a patient with ostium secundum ASD.
Case Summary: A 77-year-old man was admitted with a 2-year history of chest tightness and shortness of breath.

Article Synopsis
- * Atrial septal defect (ASD) is a common congenital heart issue, which can lead to symptoms like fatigue and shortness of breath, especially when larger.
- * A unique case is presented of a 15-year-old male with dizziness and a complete heart block; treatment involved closing a patent foramen ovale (PFO) and fitting a pacemaker, successfully resolving his symptoms.

The crochetage sign-a notch near the R-wave peak in the inferior leads-in conjunction with right axis deviation, complete or incomplete right bundle branch block, and right ventricular hypertrophy (R/S ratio >1 in lead V1) on 12-lead electrocardiogram are highly suggestive of atrial septal defect.

Introduction: Atrial Septal Defect by virtue of its left to right shunt induces geometric and electrical remodeling of the right sided chambers of the heart which produces prototypical changes in the Electrocardiogram. Various patterns produced by ASD in the ECG can give a clue in diagnosing the defect. Reversal of remodeling after the shunt closure and its accompanying changes in ECG are also helpful in follow up of these patients Methodology: This is a retrospective cohort analysis, wherein, ECG of the patients who have undergone ASD closure by percutaneous device closure or surgical closure during the study period,were obtained from hospital records and they were followed up.
