Insights
This study evaluated surgical management for congenital heart disease in children from Papua New Guinea (PNG). The program was successful for a small group, with acceptable outcomes for the era.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Surgery
- Global Health
Background:
- Congenital heart disease (CHD) poses significant challenges in low-resource settings.
- Surgical management programs for CHD in developing nations require critical analysis.
- Papua New Guinea (PNG) has limited access to specialized pediatric cardiac care.
Purpose of the Study:
- To critically analyze the surgical management program for children with congenital heart disease in PNG.
- To document the patterns, management, and short-term outcomes of PNG children undergoing cardiac surgery in Australia.
- To assess the success and limitations of this international referral program.
Main Methods:
- Retrospective hospital record analysis of 165 children referred from PNG (1978-1994).
- Data collected included demographics, clinical presentation, diagnostic workup (echocardiography, cardiac catheterization), surgical procedures, and outcomes.
- Analysis focused on common CHD types, surgical approaches, complications, and mortality.
Main Results:
- Ventricular septal defect (34%), tetralogy of Fallot (23%), and patent ductus arteriosus (16.4%) were the most common defects.
- 133 children (81%) underwent surgery, predominantly open-heart procedures (75%).
- The overall mortality rate was 6%, considered acceptable for the period.
Conclusions:
- The surgical management program was successful for a subset of PNG children with CHD.
- Certain complex lesions were under-represented, indicating potential gaps in diagnosis or referral.
- The program demonstrated feasibility and acceptable outcomes in a resource-limited context during that era.
Abstract:
The aim of the study was to analyse critically the programme for surgical management of children in Papua New Guinea (PNG) with congenital heart disease. A hospital record-based analysis was undertaken to document the pattern, management and short-term outcome of surgery in PNG children referred with a diagnosis of congenital heart disease to the Royal Alexandra Hospital for Children in Sydney, Australia. On admission, physical examination, chest radiogram, electrocardiogram, cross-sectional echocardiogram and, in most cases, cardiac catheterization were performed. Of the 170 children referred over the 17-year period, 1978-1994, 165 were confirmed to have congenital heart disease and were included in the study. Their ages ranged from 2 months to 16 years (median 5.5) and the male to female ratio was 1:1. One-sixth had delayed milestones and one-fifth long-term wasting. A large number were tachypnoeic, in heart failure or had pulmonary hypertension on admission. Ventricular septal defect, 34%, tetralogy of Fallot, 23%, and patent ductus arteriosus, 16.4%, were the predominant defects. lesions such as aortic stenosis, coarctation of the aorta and transposition of the great arteries are under-represented. Altogether, 133 children (81%) had surgery; 75% were open- and 25% closed-heart operations. The complications were unremarkable and the mortality rate (6%) acceptable for the era. The programme was therefore very successful for a small proportion of children born in PNG with congenital heart disease.
