SPECTRUM OF CONGENITAL HEART DISEASES (CHD) IN OLDER CHILDREN AND ADULT POPULATION

Abstract

Objective: To determine the spectrum of congenital heart diseases in older
children and adult population.
Methodology: This was a retrospective cross-sectional study. Data retrieved
from computerized database of Echocardiography section of Cardiology
department Lady Reading Hospital Peshawar from Feb: 2004 to Oct: 2011.Newly
diagnosed CHD patients' age more than 15 years who have not undergone
previous intervention (Surgical or Transcatheter) were included in the study.
Patients were subdivided into 3 groups on the basis of age. Group A include age
16-35years, group B 36-50years and group C more than 50 years. Frequencies
of various types of CHD were determined using SPSS version 16.
Results: A total of 1413 patients were included in the study. Female patients were 742 (52.5%).Mean age in years was 27.91 ±11.94 (range 16-80). Number of patients in different groups were as follow: Group A= 80.2%(1133), Group
B=15.2%(215) and Group C= 4.6%(65). The relative no of patients with
different diseases were ASD 30.6%(432), VSD 18.9%(267),PDA 18.5%(261),
P.S 12.7%(180), Mixed lesions 7.7%(109), TOF 7.14%(101), TGA 1.5%(21), Co
arctation of aorta1.2%(17), Ebstien`s anomaly 0.9%(13), A-V canal defect
0.6%(9), Truncus Arteriosus 0.2%(3).ASD was the most frequent CHD in all age
groups. There was no patient with Coarctation of Aorta in group C.
Conclusion: CHD is a frequent diagnosis in population above 15 years of age.
Attempts should be made to provide early diagnosis so that defects can be
corrected in infancy or early childhood to avoid permanent damage.
