METHODS: Over a 3-year period a group of pregnant women with cardiac disease was followed until 6 weeks postpartum. Twenty women with pulmonary hypertension were compared with 20 controls without pulmonary hypertension with particular reference to maternal and fetal outcome. Analysis of data was carried out using Fisher's exact test and Student's t-test.

RESULTS: Except for Eisenmenger's syndrome, there were no differences in maternal morbidity and mortality between the two groups. There were more low birth weight babies but no significant differences in premature delivery rate, mode of delivery or perinatal mortality.

SETTING: An academic medical center.

METHODS: Patients with PH who underwent either a primary or revisional bariatric surgery between 2005 and 2015 and had a preoperative right ventricle systolic pressure (RVSP) ≥35 mm Hg were included.

RESULTS: Sixty-one patients met the inclusion criteria. Fifty (82%) were female with the median age of 58 years (interquartile range [IQR] 49-63). The median body mass index was 49 kg/m2 (IQR 43-54). Procedures performed included the following: Roux-en-Y gastric bypass (n = 33, 54%), sleeve gastrectomy (n = 24, 39%), adjustable gastric banding (n = 3, 5%), and banded gastric plication (n = 1, 2%). Four patients (7%) underwent revisional bariatric procedures. Median operative time and length of stay was 130 minutes (IQR 110-186) and 3 days (IQR 2-5), respectively. The 30-day complication rate was 16% (n = 10) with pulmonary complications noted in 4 patients. There was no 30-day mortality. One-year follow-up was available in 93% patients (n = 57). At 1 year, median body mass index and excess weight loss were 36 kg/m2 (IQR 33-41) and 51% (IQR 33-68), respectively. There was significant improvement in the RVSP after bariatric surgery at a median follow-up of 22 months (IQR 10-41). The median RVSP decreased from 44 (IQR 38-53) to 40 mm Hg (IQR 28-54) (P = .03).
