Introduction
• Congenital heart disease (CHD) refers to
structural or functional heart disease that is
present at birth even if it is discovered much
later
• CHD: Occurs in approximately 8/1000 live
births.
• No available data on prevalence of CHD from
Meghalaya
Aims and objectives
• The present study was conducted
to ascertain the spectrum of
Congenital heart disease in
Meghalaya (0 to 18 years old).
Material and methods
• Study design: Retrospective study from Jan’05 to June’07 (2.5 years).
• Place of study: Dept. of Pediatric Disciplines,NEIGRIHMS,Shillong.
• Age group: 0 to 18 years of age.
• Data on congenital heart diseases were collected in semi structured
proforma and analysed.
• The source of information was all outpatient and inpatient records
including echocardiography records from Jan’05 to June’07
• Exclusion criteria included CHDs with associated syndromes,
since the present study was to know the prevalence of isolated
CHDs in Meghalaya.
Results and observations
• Total no of cases seen
during study period:
12,322.
• Congenital heart
disease: 286(2.32%).

Discussion contd…
• The frequency of rare types of CHDs like
AS,PS, TGA,TA,ECD were less in the present
study.
• Most of the CHDs were diagnosed during
infancy(26.92%) which was in accordance
with the other studies.
• Prevalence was slightly higher in females as
compared to the males.
Discussion contd…
• The prevalence of CHDs in the study was
increasing from 2005 to 2007 (9.79% in JanJune’05 to 31.81% in Jan-June’07).
• Increasing number of OPD visits,
improvement of diagnosis, attention or
awareness among the referring
government / private sector doctors might be
the causes for the increase.
Conclusion
The present findings indicate that,
(a) Prevalence of CHDs in Meghalaya is not as
high as the prevalence reported by other Indian
studies.
(b) However, it is an important disease which
requires immediate attention and highlights
the need for appropriate cardio-thoracic
surgical services accessible to the common
man in this region .
