This study aimed to evaluate the accuracy of echocardiographic estimates of pulmonary artery pressure compared with simultaneous right heart catheterization (RHC) in patients with severe TR.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p xml:lang=\"en\">In this prospective observational study, a total of 48 patients with severe TR were enrolled between September 2021 and August 2024 at an experienced RHC center. Data were obtained by simultaneously measuring echocardiography and RHC parameters. The correlation between pulmonary arterial systolic pressure (PASP) measured by echocardiography and RHC was analyzed using Pearson correlation and Bland\u2013Altman analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">\n                      The median age was 71.5\u2009years, and 26 (54.2%) of the patients were women. Forty\u2010three (89.6%) patients had secondary TR as the underlying pathogenesis. There was a good correlation (\n                      <jats:italic toggle=\"no\">r<\/jats:italic>\n                      =0.85 as Pearson correlation,\n                      <jats:italic toggle=\"no\">P<\/jats:italic>\n                      &lt;0.001) between PASP measurements obtained via echocardiography and RHC, with a bias of +1.3\u2009mm\u2009Hg and 95% limits of agreement ranging from \u221212.8 to 15.5\u2009mm\u2009Hg. Incorporating parameters such as inferior vena cava collapsibility of \u226420%, hepatic vein systolic flow reversal, and the V\u2010wave cutoff sign further stratified the estimated right atrial pressure to 10, 15, or 20\u2009mm\u2009Hg in patients initially estimated to have a right atrial pressure of 15\u2009mm\u2009Hg (\n                      <jats:italic toggle=\"no\">P<\/jats:italic>\n                      &lt;0.001).
