Abstract
Aims: To identify the annual incidence of congenital heart disease (CHD) in our population and to assess the pick up rate during antenatal ultrasound.
Methods: Retrospective analysis of cases diagnosed with CHD between January 2007 - April 2010.
Results: Forty-four cases of CHD were diagnosed during the study period. Of these, 19 cases were diagnosed antenatally and 25 cases postnatally.
Of the19 cases:
-
7 four-chamber anomalies
-
7 out-flow tract anomalies and
-
5 cases of cardiomegaly
5 cases were terminated [associated with syndromes], 2 resulted in miscarriages, 5 suffered neonatal deaths and 7 survived (survival rate- 37%).
Of the 25 cases diagnosed postnatally:
Twenty babies were term deliveries and 5 were pre-term. 16-cases (64%) were diagnosed within the 1st month of delivery.
Eight (32%) of the 25 cases were cyanotic CHD.
Following are the specific diagnosis of postnatal CHD.
-
Transposition of great arteries- 4
-
Aortic stenosis- 1
-
Pulmonary stenosis- 5
-
Septal defects- 7
-
Ebstein anomaly- 1
-
Tetralogy of Fallot- 3
-
Coarctation of aorta- 2
-
Dextrocardia- 1
-
Coronary artery fistula- 1
16-cases were treated with surgical corrections and 9-cases treated conservatively. 24-neonates survived (survival rate- 96%).
Conclusion: Annual incidence rate of CHD in our population was 1.4% with 43% of cases identified during antenatal scans. Following the audit, following measures have been introduced.
-
Merging antenatal cardiac clinics and paediatric cardiac clinics
-
“Tiny Tickers”- The Regional Foetal Cardiac Training Group for the Ultrasonographers are introducing a training program.
