A case series describing the multidisciplinary management of pulmonary arterial hypertension in pregnancy: Time for optimism.

Abstract

Pulmonary arterial hypertension (PAH) is a high-risk condition during pregnancy, with recent literature describing mortality rates of up to 23%. To describe the course and outcomes of pregnancy for women with PAH in a major Australian metropolitan referral centre over a 15-year period. Retrospective review of medical records of all pregnant women with PAH over the period 2005-2020. We report the outcomes of nine pregnancies in six women. In five women, seven pregnancies proceeded to term with birth of a healthy neonate, five vaginal births and two caesareans. Two women opted for a termination of pregnancy in the first trimester following counselling. The planning of care and patient-centred decision-making was individually tailored by a multidisciplinary team. The pulmonary hypertension clinic provided specialist support including the management of pulmonary vasodilators. All women who delivered a live offspring received neuraxial anaesthesia. Women with this condition are ideally managed in a centre with expertise in PAH; counselling regarding the risks is imperative. Regional anaesthesia, irrespective of the mode of delivery, facilitated safe delivery and improved patient experience. The option of aiming for a term vaginal birth needs to be considered in these complex women.
