We investigated the impact of rPS according to RV ejection fraction (RVEF).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>METHODS<\/jats:title>\n                  <jats:p>In this multicentre, retrospective study, 117 repaired tetralogy of Fallot patients who underwent surgical pulmonary valve insertion for more than moderate PR between 2003 and 2021 were examined. Regarding rPS, the threshold for PR with rPS (PSR) and PR was 25\u2009mmHg. For RVEF, the threshold for preserved RVEF (pEF) and reduced RVEF (rEF) was 40%. The patients were divided into 4 groups: patients with PR and pEF (PR-pEF) (n\u2009=\u200948), those with PR and rEF (PR-rEF) (n\u2009=\u200944), those with PSR and pEF (PSR-pEF) (n\u2009=\u200916), and those with PSR and rEF (PSR-rEF) (n\u2009=\u20099). Clinical parameters, postoperative adverse event rates and their associations were studied.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>The 5-year freedom from adverse cardiovascular events was the highest in the PSR-pEF and the lowest in the PSR-rEF groups. The PSR-rEF group had the highest RV end-diastolic pressure (RVEDP) (12\u2009\u00b1\u20092.2\u2009mmHg) (P = 0.006). From multivariable analysis, RVEDP was associated with postoperative adverse events (P = 0.016). RVEDP\u2009&amp;gt;\u20098 mmHg was associated with a lower freedom from adverse events.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSIONS<\/jats:title>\n                  <jats:p>The freedom from adverse events was the lowest in the PSR-rEF group, with the highest RVEDP, suggesting RV systolic and diastolic dysfunction.
