FREQUENCY OF COMPLETE HEART BLOCK AFTER SURGICAL CLOSURE OF PERIMEMBRANOUS VENTRICULAR SEPTAL DEFECT

Objective: To find the frequency of complete heart block (CHB) in patients undergoing surgical perimembranous Ventricular septal defect (VSD) closure. Methodology: This was a Descriptive cross sectional study performed in Cardiovascular Department Lady Reading Hospital Peshawar. Data was collected from 28 January 2013 to 28 July 2013 with sample size of 103.Sampling technique was non probability consecutive. All patients with perimembranous ventricular septal defect, aged 5 years to 25 years with any gender were included in the study. Results:-Mean age was 12.63 years ± 6.63. Patients were divided in four categories according to their age. Over all complete heart block in the perimembranous ventricular septal defect after surgical closure was 10(9.71%). Age wise distribution of complete heart block shows that majority of the complete heart block 6(12.8%) were found in age less than or equal to 10 years. Conclusion:-VSD closure is less often associated with CHB but there should be arrangements for pace maker to timely pace the patient in case of any emergency.
