Risk factors for moderate to severe pulmonary insufficiency (PI) and surgical or catheter intervention for right ventricular outflow tract (RVOT) obstruction were analyzed.\n                    <jats:bold>Results:<\/jats:bold>\n                    During a median follow-up time of 6 years (range 1 month to 17 years), 5\/70 (7%) patients required surgical or catheter intervention for isolated RVOT obstruction, 8\/70 (11%) had moderate or severe PI, and 3\/70 (4%) had a combined outcome of RVOT obstruction and PI. Patients who required reintervention had smaller pulmonary valve (PV) z-score (\u22122.8 vs \u22121.7,\n                    <jats:italic>P\u2009<\/jats:italic>\n                    &lt;\u2009.01), were more likely to have isolated infundibular patching (75% vs 31%,\n                    <jats:italic>P<\/jats:italic>\n                    \u2009=\u2009.02), and had smaller PV z-score at the end of the procedure (\u22121.4 vs \u22121.0,\n                    <jats:italic>P<\/jats:italic>\n                    \u2009=\u2009.03). Patients with significant PI were more likely to have intraoperative valvotomy via Hegar dilation (36% vs 13%,\n                    <jats:italic>P<\/jats:italic>\n                    \u2009=\u2009.04). The strongest independent predictors of RVOT obstruction and\/or PI were preoperative cyanotic episodes (odds ratio 6.0, 95%CI: 1.6-22,\n                    <jats:italic>P<\/jats:italic>\n                    \u2009=\u2009.01) and valvotomy via Hegar dilation (odds ratio 4.6, 95%CI: 1.0-21,\n                    <jats:italic>P<\/jats:italic>\n                    \u2009=\u2009.04).\n                    <jats:bold>Conclusions:<\/jats:bold>\n                    Valve-sparing repair of TOF is less likely to be successful if reliant on isolated infundibular patching or not achieving at least a z-score of \u22121 at the PV at the completion of the procedure. Repairs using blind dilation destabilize the valve and lead to long-term valve incompetence.\n                  <\/jats:p>","DOI":"10.1177\/21501351241313311","type":"journal-article","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T06:23:22Z","timestamp":1740119002000},"page":"595-602","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Predictors of Success Following Valve-Sparing Repair of Tetralogy of Fallot"],"prefix":"10.1177","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9143-6819","authenticated-orcid":false,"given":"Paighton C.","family":"Miller","sequence":"first","affiliation":[{"name":"Department of Surgery, Washington University School of Medicine, St. Louis, MO, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael R.","family":"Chomat","sequence":"additional","affiliation":[{"name":"Division of Pediatric Critical Care, Department of Pediatrics, University of Texas at Austin, Dell Children's Medical Center, Austin, TX, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fei","family":"Wan","sequence":"additional","affiliation":[{"name":"Department of Surgery, Washington University School of Medicine, St. Louis, MO, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacob R.","family":"Miller","sequence":"additional","affiliation":[{"name":"Division of Cardiothoracic Surgery, Department of Surgery, Section of Pediatric Cardiothoracic Surgery, Washington University School of Medicine, St. Louis Children's Hospital, St. Louis, MO, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dilip","family":"Nath","sequence":"additional","affiliation":[{"name":"Division of Cardiothoracic Surgery, Department of Surgery, Section of Pediatric Cardiothoracic Surgery, Washington University School of Medicine, St. Louis Children's Hospital, St. Louis, MO, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pirooz","family":"Eghtesady","sequence":"additional","affiliation":[{"name":"Division of Cardiothoracic Surgery, Department of Surgery, Section of Pediatric Cardiothoracic Surgery, Washington University School of Medicine, St. Louis Children's Hospital, St. Louis, MO, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,2,21]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1001\/jamacardio.2018.4255"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1053\/j.semtcvs.2018.10.015"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1053\/j.semtcvs.2019.04.007"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1093\/ejcts\/ezz331"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2022.05.063"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-4975(02)03586-5"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1747-0803.2007.00131.x"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1017\/S1047951114001991"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1053\/j.semtcvs.2018.11.008"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.1053\/j.semtcvs.2018.10.014"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2017.08.147"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCIMAGING.117.006979"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jclinepi.2004.04.003"},{"key":"e_1_3_3_15_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.athoracsur.2005.04.016"},{"issue":"3","key":"e_1_3_3_16_2","first-page":"565","article-title":"The role of primary surgical repair technique on late outcomes of Tetralogy of Fallot: a multicentre study","volume":"57","author":"Padalino MA","year":"2020","unstructured":"Padalino MA, Pradegan N, Azzolina D, et al.
