Abstract:
Background: Congenital heart disease (CHD) is the commonest single group of
congenital abnormalities which require proper evaluation and timely intervention.
Studies on pattern of CHD have been done in various countries but such studies are
very limited in Bangladesh.
Objective: This study was undertaken to evaluate the current pattern of congenital
heart disease in Bangladesh.
Methods: This study was conducted over a period of 1 year from January 2008 to
December 2008. Data were collected prospectively from Dhaka Shishu Hospital (DSH)
and retrospectively from hospital records during the same period from Combined
Military Hospital (CMH), Dhaka; National Institute of Cardiovascular disease (NICVD)
and Bangabandhu Sheikh Mujib Medical University (BSMMU) Dhaka. All children
with confirm diagnosis of CHD within the age ranging from 1st day of life to 12 years
were included in the study.Results: In this study at DSH, Dhaka CMH, NICVD and BSMMU total 319, 1220,
3548 and 950 cases were diagnosed as CHD and the percentage of CHD detected
during neonatal period was 25.08%, 30%, 25% and 7.9% respectively. Majority of the
cases were diagnosed during infancy. In DSH cyanotic CHD was 21.94% and acyanotic
CHD was 78.06% but in CMH 16.56% and 83.44%, in NICVD 25.14% and 74.86%
and in BSMMU 15.79% and 84.21% respectively. VSD remains at the top of the list
followed by ASD, PDA, TOF and TGA in decreasing frequency. VSD was the
commonest among acyanotic CHD and TOF was the commonest cyanotic CHD.
Conclusion: This study gives an overview of the pattern of CHD in Bangladesh as
these four hospitals receive major number of paediatric cardiac patients
including patients referred by other hospitals from every part of Bangladesh. Therefore
we can assume that this study represents national scenario and may help to assess
the pattern of CHD in Bangladesh.
