Fetal cardiac diagnosis and its influence on the pregnancy and newborn--a tertiary centre experience

To evaluate the impact of an abnormal fetal cardiac scan on the management of the pregnancy and the outcome of the newborn. We reviewed all pregnancies that were referred to the Fetal Cardiac Unit for assessment to determine if the finding of a cardiac abnormality influenced the pregnancy and fetus, timing and mode of delivery, the treatment and outcome of the newborn. Diagnoses were confirmed by echocardiography following the baby's delivery. Between January 2005 and July 2006, there were 251 detailed fetal cardiac scans carried out on at risk pregnancies or those with suspected abnormal scans in 127 fetuses. Seven of the 92 mothers with abnormal fetal cardiac scans opted for termination. Two were successfully treated during the pregnancy for hydrops fetalis arising from a tachyarrhythmia. One was induced early because of deterioration of fetal well-being and increasing cardiac size. Twenty-six infants required a prostaglandin infusion prior to surgery. Two required intensive care for associated malformations. There were 24 survivors following complex surgery, and 2 deaths. Two infants with severe tricuspid valve incompetence from a dysplastic valve died, one associated with a septicaemia and the other where surgery was delaye...Continue Reading
