Right-heart trans-tricuspid Doppler and tissue Doppler echocardiographic techniques can be combined to calculate the right ventricular (RV) E\/e\u2032 ratio \u2013 a reflection of RV filling pressure which is a surrogate of RAP. A systematic search was undertaken which found seventeen articles that compared invasively measured RAP with RV-E\/e\u2032 estimated RAP. Results commonly concerned pulmonary hypertension or advanced heart failure\/transplantation populations. Reported receiver operating characteristic analyses showed reasonable diagnostic ability of RV-E\/e\u2032 for estimating RAP in patients with coronary artery disease and RV systolic dysfunction. The diagnostic ability of RV-E\/e\u2032 was generally poor in studies of paediatrics, heart failure and mitral stenosis, whilst results were equivocal in other diseases. Bland\u2013Altman analyses showed good accuracy but poor precision of RV-E\/e\u2032 for estimating RAP, but were limited by only being reported in seven out of seventeen articles. This suggests that RV-E\/e\u2032 may be useful at a population level but not at an individual level for clinical decision making. Very little evidence was found about how atrial fibrillation may affect the estimation of RAP from RV-E\/e\u2032, nor about the independent prognostic ability of RV-E\/e\u2032 . Recommended areas for future research concerning RV-E\/e\u2032 include; non-sinus rhythm, valvular heart disease, short and long term prognostic ability, and validation over a wide range of RAP.<\/jats:p>","DOI":"10.1530\/erp-19-0057","type":"journal-article","created":{"date-parts":[[2020,12,9]],"date-time":"2020-12-09T03:16:49Z","timestamp":1607483809000},"page":"R11-R20","update-policy":"https:\/\/doi.org\/10.1530\/erp\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":21,"title":["Echocardiographic RV-E\/e\u2032 for predicting right atrial pressure: a review"],"prefix":"10.1186","volume":"7","author":[{"given":"A J","family":"Fletcher","sequence":"first","affiliation":[{"name":"1Department of Cardiac Physiology, Royal Papworth Hospital NHS Foundation Trust, Cambridge Biomedical Campus, Cambridge, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S","family":"Robinson","sequence":"additional","affiliation":[{"name":"2Department of Cardiac Investigations, North West Anglia NHS Foundation Trust, Peterborough City Hospital, Bretton Gate, Peterborough, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B S","family":"Rana","sequence":"additional","affiliation":[{"name":"3Department of Cardiology, Imperial College London NHS Foundation Trust, London, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","container-title":["Echo Research and Practice"],"original-title":[],"link":[{"URL":"https:\/\/erp.bioscientifica.com\/view\/journals\/echo\/7\/4\/ERP-19-0057.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/erp.bioscientifica.com\/downloadpdf\/journals\/echo\/7\/4\/ERP-19-0057.xml","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,12,13]],"date-time":"2023-12-13T05:10:31Z","timestamp":1702444231000},"score":1,"resource":{"primary":{"URL":"https:\/\/echo.biomedcentral.com\/articles\/10.1530\/ERP-19-0057"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,12]]},"references-count":0,"journal-issue":{"issue":"4"},"URL":"https:\/\/doi.org\/10.1530\/erp-19-0057","relation":{},"ISSN":["2055-0464"],"issn-type":[{"value":"2055-0464","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,12]]}}}
