In a population enriched for PVD, we sought to establish qualitative grades and prognostic value of right heart chamber size and function.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>METHODS:<\/jats:title>\n            <jats:p>We investigated 1053 study participants in PVDOMICS (Redefining Pulmonary Hypertension Through the PVD Phenomics Program) to determine clinical and echocardiographic differences associated with increasing pulmonary vascular resistance severity. Right heart chamber size and function were qualitatively assessed using a percentile-based approach above the median values to create a clinical grading system for right heart adaptation. The relationship between echocardiographic categories and all-cause mortality was examined using survival analyses adjusted for potential confounders.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>RESULTS:<\/jats:title>\n            <jats:p>\n              A stepwise increase in adverse right heart remodeling was observed with a concomitant decrease in functional parameters by pulmonary vascular resistance strata (\n              <jats:italic toggle=\"yes\">P<\/jats:italic>\n              &lt;0.001 for all). Mild, moderate, and severe categories of right heart chamber size and dysfunction were defined using a percentile-based approach across the spectrum of PVD. During a median follow-up of 2.07 years (interquartile range, 1.23\u20133.01 years), 130 participants died (11.4%). Progressive pulmonary vascular resistance increase and 2DE evidence of right heart dysfunction inclusive of fractional area change, and right ventricular global longitudinal strain were independently associated with increased all-cause mortality risk in multivariate analysis adjusted for age, disease duration, and male sex.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>CONCLUSIONS:<\/jats:title>\n            <jats:p>In this well-characterized sample of adults with diverse etiologies and varying PVD severity, we define categories of abnormal right heart chamber size and function. Further, we demonstrate a stepwise relationship between these categories of abnormal morphology and function and all-cause mortality. Defining grades of right ventricular dysfunction in individuals with known PVD has important clinical implications for monitoring disease progression and response to therapies.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/circimaging.124.017074","type":"journal-article","created":{"date-parts":[[2024,10,15]],"date-time":"2024-10-15T18:00:59Z","timestamp":1729015259000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":21,"title":["Defining Echocardiographic Degrees of Right Heart Size and Function in Pulmonary Vascular Disease From the PVDOMICS Study"],"prefix":"10.1161","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6088-0773","authenticated-orcid":true,"given":"Monica","family":"Mukherjee","sequence":"first","affiliation":[{"name":"Johns Hopkins University School of Medicine, Baltimore, MD (M.M., S.C.M., V.P.J., C.E.S., P.M.H.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3188-7209","authenticated-orcid":true,"given":"Stephen C.","family":"Mathai","sequence":"additional","affiliation":[{"name":"Johns Hopkins University School of Medicine, Baltimore, MD (M.M., S.C.M., V.P.J., C.E.S., P.M.H.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8610-0533","authenticated-orcid":true,"given":"Christine","family":"Jellis","sequence":"additional","affiliation":[{"name":"Cleveland Clinic Medical Center, OH (C.L.J., W.H.W.T., M.M.P., G.B., S.E., D.H.K.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1075-5047","authenticated-orcid":true,"given":"Benjamin H.","family":"Freed","sequence":"additional","affiliation":[{"name":"Northwestern University Feinberg School of Medicine, Division of Cardiology, Chicago, IL (B.H.F., J.D.T.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7117-1075","authenticated-orcid":true,"given":"Lisa R.","family":"Yanek","sequence":"additional","affiliation":[{"name":"Johns Hopkins University Biostatistics, Division of General Internal Medicine, Baltimore, MD (L.R.Y.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hannah","family":"Agoglia","sequence":"additional","affiliation":[{"name":"Weil Cornell Medicine Division of Cardiology, New York (H.A., C.C., E.M.H., J.K.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-9506-7981","authenticated-orcid":true,"given":"Caitlin","family":"Chiu","sequence":"additional","affiliation":[{"name":"Weil Cornell Medicine Division of Cardiology, New York (H.A., C.C., E.M.H., J.K.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3811-4973","authenticated-orcid":true,"given":"Vivek P.","family":"Jani","sequence":"additional","affiliation":[{"name":"Johns Hopkins University School of Medicine, Baltimore, MD (M.M., S.C.M., V.P.J., C.E.S., P.M.H.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2388-5660","authenticated-orcid":true,"given":"Catherine E.","family":"Simpson","sequence":"additional","affiliation":[{"name":"Johns Hopkins University School of Medicine, Baltimore, MD (M.M., S.C.M., V.P.J., C.E.S., P.M.H.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5843-3392","authenticated-orcid":true,"given":"Evan L.","family":"Brittain","sequence":"additional","affiliation":[{"name":"Vanderbilt University, Nashville, TN (E.L.B., A.R.H.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8335-735X","authenticated-orcid":true,"given":"W.H.
