Material and Methods: This retrospective study was conducted at Department of Cardiology, Postgraduate Medical Institute, Lady Reading Hospital, Peshawar. Patients referred for echocardiography were reviewed. Trans-thoracic two dimensional echocardiography and Doppler studies were done on all cases. The results were analyzed from the data retrieved from the computerized data base of Cardiology department from July 1998 to December 2005 covering almost seven years and six months. Records of patient aged twelve and below and labeled as congenital heart disease were analyzed on SPSS windows version 10.
Results: Out of 3072 patients with CHD, 83.7% were acyanotic heart diseases. Ventricular septal defect was present in 1248 patients (40.6%), atrial septal defects (ASD) were 493 (16%) comprising of ASD secundum in 397 (12.9%) and ASD primum in 96 (3.1%) patients. PDA was present in 394 patients (12.8%). A total of 473 patients (15.4%) had the tetrology of Fallot and 236 patients (7.7%) had pulmonic stenosis. Complex congenital heart diseases were present in 198 (6.4%) patients and coarctation of aorta was found in 0.9%.
Conclusion: Majority of the congenital cardiac anomalies in patients less than 12 years of age are acyanotic. VSD and ASD are the major acyanotic and TOF is the major cyanotic congenital heart disease.
