Profile of Acyanotic Congenital Heart Defects

Abstract

Background: Acyanotic CHD constitute majority of heart defect with significant morbidity, Profile of various defects is essential for identifying children who need urgent intervention and who need to be medically followed. Methods: The study was carried out in Department of Pediatrics and Center of Cardiology, Jawaharlal Nehru Medical College, Aligarh. All patients referred with complaints or clinical examination suggestive of congenital heart defects were further evaluated with echocardiography. On echocardiography patients having congenital heart defects were included as cases which were further divided into cyanotic and acyanotic heart defects, preterms having PDA and PFO and those with acquired heart defects were excluded. The profile and mode of presentation of various acyanotic CHDs was further described in detail. Results: Acyanotic heart defects were 290(72.50%) of the total heart defects, while the contribution of cyanotic heart defects was 110 (27.50%). Out of all CHDs, VSD was the most common lesion with contribution of 152 (38.00%) cases, followed by ASD (20.34%) , PDA (13.10%), PS (6.90%), Subaortic Membrane (2.00%), AV Canal valve defect (1.00%), RSOV (1.00%), Bicuspid Aortic Valve (1.00%), PAPVC (0.66%), Cortriatriatum (0.33%), Coarctation of Aorta(0.33%), ALCAPA(0.33%) and Aortic stenosis (0.33%). Age of presentation for most of the children was between 1 to 5 years. Conclusions: The profile and mode of presentation of various acyanotic heart defects was similar to other studies but diagnosis was delayed in majority of cases. The prevelance of various obstructive lesions like AS, coarctation and bicuspid aortic valve was much lower.
