Pulmonary hypertension and pregnancy: The experience of a tertiary institution over 15 years

Background: Pulmonary hypertension (PH) in pregnancy is associated with a high maternal mortality and morbidity and has been found to be as high as 30-56%. Aim: To review the management of such patients in a tertiary center over a 15 year period, as the current literature consists of a few case reports, a few small case series and 2 meta-analyses. Materials and Methods: A review of all patients admitted to our institution for management of PH in pregnancy between 1994 and February 2009 was undertaken. Cases were identified from the high-risk pregnancy database within the department of anesthesia and from the hospital medical records. Severity of PH, type of PH, NYHA functional status at presentation and delivery, mode of delivery, peripartum monitoring and APGAR scores were noted. Patients were reviewed by a multidisciplinary team and management planned accordingly. Results: 19 eligible patients were identified. Patients who were significantly sick due to their PH were aggressively managed during pregnancy. Overall there was an improvement in NYHA functional status at the time of delivery. Epidural analgesia and anesthesia for labor and operatively delivery seem to be the ideal choice. Conclusion: Multidisciplinary approach is a key to the successful management of these patients. Secondary PH results in higher morbidity and mortality, in particular, older the age higher the maternal morbidity and mortality.
