The underlying pathophysiology of BPD-associated PH is complex and poorly understood. Echocardiogram may underestimate the severity of pulmonary hypertensive vascular disease in severe BPD. Digital subtraction pulmonary angiography (DSPA) is a potentially useful imaging modality for evaluating changes in the pulmonary vasculature of BPD-associated PH. In this study, we objectively quantified the pulmonary hypertensive vascular changes demonstrated by DSPA using a novel pulmonary vascular underperfusion score (PVUS) and correlated the scoring system with echocardiography parameters and cardiac hemodynamics by right heart catheterization.<\/jats:p>","DOI":"10.3390\/medicina55070359","type":"journal-article","created":{"date-parts":[[2019,7,10]],"date-time":"2019-07-10T03:05:26Z","timestamp":1562727926000},"page":"359","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Pulmonary Vascular Underperfusion Score in Premature Infants with Bronchopulmonary Dysplasia and Pulmonary Hypertension"],"prefix":"10.3390","volume":"55","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9530-8785","authenticated-orcid":false,"given":"Bibhuti B.","family":"Das","sequence":"first","affiliation":[{"name":"Joe DiMaggio Children\u2019s Hospital Heart Institute, Memorial Healthcare, Hollywood, FL 33021, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michelle-Marie","family":"Jadotte","sequence":"additional","affiliation":[{"name":"Joe DiMaggio Children\u2019s Hospital Heart Institute, Memorial Healthcare, Hollywood, FL 33021, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kak-Chen","family":"Chan","sequence":"additional","affiliation":[{"name":"Joe DiMaggio Children\u2019s Hospital Heart Institute, Memorial Healthcare, Hollywood, FL 33021, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,7,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2037","DOI":"10.1161\/CIR.0000000000000329","article-title":"Pediatric pulmonary hypertension: Guidelines from the American Heart Association and American Thoracic Society","volume":"132","author":"Steven","year":"2015","journal-title":"Circulation"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"87","DOI":"10.1164\/rccm.201409-1594OC","article-title":"Early Pulmonary Vascular Disease in Preterm Infants at Risk for Bronchopulmonary Dysplasia","volume":"191","author":"Mourani","year":"2015","journal-title":"Am.
