In this study, we aim to elucidate the risk factors contributing to PCE development post-CHS through analysis of data from a nationwide, multi-institutional database.\n                    <jats:bold>Methods:<\/jats:bold>\n                    Review of the Pediatric Health Information System Database from January 1, 2004, to December 30, 2023. All patients under the age of 18, who underwent a Society of Thoracic Surgeons benchmark procedure, were included.\n                    <jats:bold>Results:<\/jats:bold>\n                    A total of 66,695 surgeries were identified with 29,363 (44%) female, 35,084 (53%) non-Hispanic white, and median age at surgical admission of 5.1 [interquartile range: 2.0-14.1] months. Pericardial effusion occurred in 2,672 (4%) patients during the postoperative hospitalization, with the Norwood procedure having the highest incidence (245\/2,726, 8.9%). Multivariable analysis revealed the Norwood procedure as having the highest adjusted odds of PCE (odds ratio [OR]: 2.34, 95%CI: 1.98-2.75,\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    \u2009&lt;\u2009.001) when compared with isolated ventricular septal defect repair. Pericardial effusion was associated with a 16% (95%CI: 9.8-12.3,\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    \u2009&lt;\u2009.001) increase in length of stay and increased mortality (OR: 1.84, 95%CI: 1.50-2.25,\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    \u2009&lt;\u2009.001). Furthermore, 647 (1%) patients, out of 65,442 who survived to index hospital discharge, were readmitted due to PCE within 90 days of discharge. Fontan patients had the highest incidence of readmission (138\/7,873, 1.7%) and increased adjusted odds for readmission (OR: 1.77, 95%CI: 1.37-2.28,\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    \u2009&lt;\u2009.001).\n                    <jats:bold>Conclusions:<\/jats:bold>\n                    Incidence of PCE after CHS is low at 4%. However, certain procedures have an incidence as high as 8.9%. Pericardial effusion poses significant postoperative clinical challenges with increased mortality and resource utilization. Vigilant monitoring and targeted interventions in high-risk patients are essential for mitigating the impact of PCE on postoperative outcomes.\n                  <\/jats:p>","DOI":"10.1177\/21501351251322876","type":"journal-article","created":{"date-parts":[[2025,9,9]],"date-time":"2025-09-09T17:05:20Z","timestamp":1757437520000},"page":"52-60","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Incidence and Outcomes of Pericardial Effusion After Congenital Heart Surgery"],"prefix":"10.1177","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3731-5984","authenticated-orcid":false,"given":"Mario","family":"O\u2019Connor","sequence":"first","affiliation":[{"name":"The University of Texas at Austin Dell Medical School"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlos M.","family":"Mery","sequence":"additional","affiliation":[{"name":"Vanderbilt University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Neil M.","family":"Venardos","sequence":"additional","affiliation":[{"name":"Oklahoma Children's Hospital"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeremy","family":"Affolter","sequence":"additional","affiliation":[{"name":"The University of Texas at Austin Dell Medical School"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Charles","family":"Fraser","sequence":"additional","affiliation":[{"name":"The University of Texas at Austin Dell Medical School"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0725-2791","authenticated-orcid":false,"given":"Andrew","family":"Well","sequence":"additional","affiliation":[{"name":"The University of Texas at Austin Dell Medical School"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,9,9]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrtlng.2020.10.011"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1136\/heart.89.7.780"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00246-022-02820-4"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00246-018-2031-4"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11886-016-0791-0"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1161\/JAHA.118.011118"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1093\/ejcts\/ezab449"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.xjon.2022.01.001"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2021.10.002"},{"key":"e_1_3_2_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2021.10.015"},{"key":"e_1_3_2_12_2","unstructured":"R Core Team.
