Even though current guidelines only recommend measurement of RA dimensions at the end of ventricular systole in these patients, there is paucity of information regarding the potential utility of RA dimensions obtained at the end of ventricular diastole.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In this retrospective study, standard echocardiographic data were collected from 80 studies. The population studied was divided into Group I that consisted of 35 patients (52\u00a0\u00b1\u00a010\u00a0years) without PH while Group II included 45 patients (56\u00a0\u00b1\u00a014\u00a0years; P\u00a0=\u00a00.2) with cPH. RA measurements were obtained not only at the end of ventricular systole, but also at the end of ventricular diastole to determine which RA measurement was more indicative of abnormal right ventricular afterload.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Even though all RA measurements were abnormal, RA area (&gt;8.4\u00a0cm<jats:sup>2<\/jats:sup>) measured at the end of ventricular diastole was the most useful RA variable to identify cPH patients with elevated pulmonary pressures (P\u00a0&lt;\u00a00.0001) and with an abnormal pulmonary vascular resistance (P\u00a0=\u00a00.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Based on these results, it appears that isolated RA measurements made at the end of ventricular systole are insufficient to fully explain the hemodynamic load of cPH. Additional studies are now required to determine whether sequential monitoring of the composite change in RA dimensions that occur throughout the cardiac cycle over time correlates better with response to vasodilator therapy and overall clinical outcomes.<\/jats:p><\/jats:sec>","DOI":"10.1111\/echo.12968","type":"journal-article","created":{"date-parts":[[2015,6,20]],"date-time":"2015-06-20T08:50:02Z","timestamp":1434790202000},"page":"1762-1770","source":"Crossref","is-referenced-by-count":1,"title":["Importance of End\u2010Diastolic Rather than End\u2010Systolic Right Atrial Size in Chronic Pulmonary Hypertension"],"prefix":"10.1111","volume":"32","author":[{"given":"Angel","family":"Lopez\u2010Candales","sequence":"first","affiliation":[{"name":"Cardiovascular Medicine Division University of Puerto Rico School of Medicine San Juan Puerto Rico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Denada S.","family":"Palm","sequence":"additional","affiliation":[{"name":"Department of Medicine University of Cincinnati College of Medicine Cincinnati Ohio"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francisco R.","family":"Lopez","sequence":"additional","affiliation":[{"name":"UC Heart Lung &amp; Vascular Institute University of Cincinnati College of Medicine Cincinnati Ohio"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Reynerio","family":"Perez","sequence":"additional","affiliation":[{"name":"Cardiovascular Medicine Division University of Puerto Rico School of Medicine San Juan Puerto Rico"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria D.","family":"Candales","sequence":"additional","affiliation":[{"name":"University of Puerto Rico Rio Piedras Puerto Rico"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,6,20]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.106.674028"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1378\/chest.114.1_Supplement.101S"},{"key":"e_1_2_5_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/echo.12419"},{"key":"e_1_2_5_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2013.10.027"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10554-012-0114-5"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcmg.2011.11.020"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ccl.2012.03.004"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijcard.2013.04.043"},{"key":"e_1_2_5_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijcard.2013.06.031"},{"key":"e_1_2_5_11_1","doi-asserted-by":"publisher","DOI":"10.1080\/AC.69.4.3036652"},{"key":"e_1_2_5_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2010.05.010"},{"key":"e_1_2_5_13_1","doi-asserted-by":"publisher","DOI":"10.1152\/ajpheart.00566.2004"},{"key":"e_1_2_5_14_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.107.653576"},{"key":"e_1_2_5_15_1","doi-asserted-by":"publisher","DOI":"10.1111\/echo.12563"},{"key":"e_1_2_5_16_1","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehr490"},{"key":"e_1_2_5_17_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8175.2008.00676.x"},{"key":"e_1_2_5_18_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1540-8167.2004.03625.x"},{"key":"e_1_2_5_19_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8175.2006.00408.x"},{"key":"e_1_2_5_20_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8175.2008.00689.x"},{"key":"e_1_2_5_21_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8175.2006.00305.x"},{"key":"e_1_2_5_22_1","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.70.4.657"},{"key":"e_1_2_5_23_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(02)02973-X"},{"key":"e_1_2_5_24_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.echo.2013.06.003"},{"key":"e_1_2_5_25_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.148.3.6878708"},{"key":"e_1_2_5_26_1","doi-asserted-by":"crossref","unstructured":"CheslerNC RoldanA VanderpoolRR et\u00a0al:How to measure pulmonary vascular and right ventricular function.
