Cardiac disease in pregnancy and the multidisciplinary team: the Wellington experience.

AIM: To define the range and severity of cardiac disease in pregnant women in New Zealand, as well as the maternal and neonatal morbidity and mortality compared with the background obstetric population.

METHODS

We retrospectively audited pregnant women with cardiac comorbidity seen by a multidisciplinary team at a tertiary referral centre consisting of midwives, cardiologists, obstetricians and anaesthetists in 2016-2017.

RESULTS

Seventy-two women were referred to the multidisciplinary team. The most common referral reasons were arrhythmia (n=20, 27.8%), congenital anomalies (n=19, 26.4%) and palpitations (n=10, 13.9%). Fifty-two of these women were found to be at increased risk of morbidity or mortality. A specific delivery plan was devised for 37 of these women (69.8%). There was no serious maternal morbidity or mortality. Instrumental delivery rates were higher for women with cardiac comorbidity than the background obstetric population (19.2% vs 10.8%, p=0.049), however, neonatal admissions were not increased (11.5% compared with 16.5%).

CONCLUSION

Multidisciplinary review of obstetric patients with cardiac disease provides an important service to ensure risk modification prior to conception and throughout pregnancy and the puerperium.
