SummaryObjective When bronchopulmonary dysplasia (BPD) is complicated by pulmonary hypertension (PH), morbidity and mortality are significantly increased. BPD-associated PH is not included in the current indications for PH medications. However, limited data demonstrate hemodynamic improvement and decreased mortality with PH-specific treatment. This report describes our 6-year experience treating BPD-associated PH with PH medications, mainly sildenafil. Study design The medical records of 20 infants diagnosed with BPD-associated PH at a tertiary pediatric pulmonary hypertension clinic in 2008–2014 were reviewed. Clinical improvement was defined as a decrease in Ross functional class by at least one degree. PH severity was classified by echocardiography as mild, moderate, or severe. Hemodynamic improvement was defined as a decrease in PH severity by at least one level. Results Eighteen out of 20 patients were treated with PH medications: 12 sildenafil, 5 sildenafil and bosentan, and 1 bosentan. Median follow-up time was 2 years. Mean functional class significantly decreased from 3.2 ± 0.9 at diagnosis to 1.7 ± 0.9 at the last follow-up. Improvement in functional class was observed in 15/16 children (94%). Moderate or severe PH was found in 13/18 children (72%) at diagnosis, and in three (17%, all moderate PH) at the last follow-up. Improvement in PH class by echocardiography was demonstrated in 14/18 children (78%). The survival rate was 95%. Conclusion Treatment of BPD complicated by PH with PH-specific medications, mainly sildenafil, is associated with improvement in both clinical and hemodynamic parameters and a low mortality rate.
