Outcomes were analyzed as risk ratios (RRs) or mean differences (MDs) with 95% confidence intervals (CIs) and pooled using the Mantel\u2010Haenszel random\u2010effects model in R (version 4.4.2).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Five RCTs enrolling 659 patients were included. CSP was associated with a significant improvement in LVEF compared with RVP (MD: 1.31%; 95% CI: 0.49 to 2.14;\n                      <jats:italic>p<\/jats:italic>\n                      \u00a0&lt;\u00a00.01).

Although associated with longer procedure times, CSP does not increase device\u2010 or lead\u2010related complications. These findings suggest that CSP offers more physiological ventricular activation while maintaining comparable safety to conventional RVP.<\/jats:p>\n                  <\/jats:sec>\n
