Patients were classified into Class 1 (no residua), Class 2 (minor residua), or Class 3 (major residua) based on TPS derived from predischarge echocardiograms and need for reintervention. Statistical methods were used to assess the association between TPS and early prognosis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 75 TOF repair patients (40% female, 60% male) were analyzed and categorized into TPS1 (24%), TPS2 (53.3%), and TPS3 (22.6%) based on pre-discharge echocardiographic findings. The median follow-up time was 7.0 months. The multivariable Cox regression analysis indicated that TPS3 scores are associated with a 12.68-fold increase in risk compared to TPS1 and TPS2 scores [95% CI\u2009=\u200912.68 (0.9\u223c179.28), <jats:italic>P<\/jats:italic>\u2009=\u20090.06]. The Spearman rank correlation analysis revealed a weak positive correlation between TPS classification and low cardiac output syndrome (<jats:italic>r<\/jats:italic>\u2009=\u20090.26, <jats:italic>P<\/jats:italic>\u2009=\u20090.03). However, there were no significant differences in ICU stay or duration of mechanical ventilation among the groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>TPS3 after intracardiac TOF repair is associated with higher risk of early re-intervention, highlighting the importance of close follow-up and monitoring in this patient population. Patients who develop low cardiac output syndrome in the early postoperative period may have residual defects that require prompt identification.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fped.2024.1274913","type":"journal-article","created":{"date-parts":[[2024,1,31]],"date-time":"2024-01-31T04:42:20Z","timestamp":1706676140000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Technical performance scores associate with early prognosis of tetralogy of Fallot repair"],"prefix":"10.3389","volume":"12","author":[{"given":"Ailixiati","family":"Alifu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haifan","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Renwei","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,1,31]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1890","DOI":"10.1016\/s0735-1097(02)01886-7","article-title":"The incidence of congenital heart disease","volume":"39","author":"Hoffman","year":"2002","journal-title":"J Am Coll Cardiol"},{"key":"B2","doi-asserted-by":"publisher","first-page":"490","DOI":"10.1097\/00000658-198610000-00017","article-title":"The first open heart corrections of tetralogy of Fallot.
