The diameter of the infundibular area was measured before ToF repair using a lateral view of angiography at end-systole and divided by the body surface area (infundibular index [mm\/m\n                    <jats:sup>2<\/jats:sup>\n                    ]). The cohort was divided into two groups, a systemic-to-pulmonary artery shunt (SPS) and a primary intracardiac repair (ICR), and compared for pulmonary annular growth and the infundibular index.\n                    <jats:bold>Results:<\/jats:bold>\n                    A total of 119 patients were included; the SPS group (n\u2009=\u200954) and the primary ICR group (n\u2009=\u200965). At ToF repair, the PV annulus was preserved in 43\/65 patients (66%) in the primary ICR group and 23\/54 (43%) in the SPS group (\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    \u2009=\u2009.0098). In a linear regression analysis, the infundibular index was significantly associated with PV growth (\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    \u2009&lt;\u2009.001). The growth of the PV annulus was significantly associated with the infundibular index in both groups. In the 60 patients with a small PV annulus (Z-score\u2009&lt;\u2009\u22122.0) at the initial presentation, logistic regression analysis showed that the infundibular index was the only factor significantly associated with PV preservation at ToF repair (\n                    <jats:italic toggle=\"yes\">P<\/jats:italic>\n                    \u2009=\u2009.005).\n                    <jats:bold>Conclusion:<\/jats:bold>\n                    The degree of infundibular stenosis has a significantly greater effect on pulmonary annular growth than the presence of an SPS, which may affect the preservation of the PV at the time of ToF repair.\n                  <\/jats:p>","DOI":"10.1177\/21501351251345812","type":"journal-article","created":{"date-parts":[[2025,7,18]],"date-time":"2025-07-18T06:57:09Z","timestamp":1752821829000},"page":"21-27","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Effect of Infundibular Stenosis on Growth of the Pulmonary Valve Annulus in Patients With Tetralogy of Fallot"],"prefix":"10.1177","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0570-8513","authenticated-orcid":false,"given":"Takashi","family":"Kido","sequence":"first","affiliation":[{"name":"Osaka University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sanae","family":"Tsumura","sequence":"additional","affiliation":[{"name":"Osaka Women's and Children's Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomomitsu","family":"Kanaya","sequence":"additional","affiliation":[{"name":"Osaka Women's and Children's Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2554-4245","authenticated-orcid":false,"given":"Koji","family":"Miwa","sequence":"additional","affiliation":[{"name":"Osaka Women's and Children's Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6011-6214","authenticated-orcid":false,"given":"Yuta","family":"Teguri","sequence":"additional","affiliation":[{"name":"Osaka Women's and Children's Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takuji","family":"Watanabe","sequence":"additional","affiliation":[{"name":"Osaka University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masaki","family":"Taira","sequence":"additional","affiliation":[{"name":"Osaka University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryo","family":"Ishii","sequence":"additional","affiliation":[{"name":"Osaka University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hidekazu","family":"Ishida","sequence":"additional","affiliation":[{"name":"Osaka University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Narita","sequence":"additional","affiliation":[{"name":"Osaka University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takayoshi","family":"Ueno","sequence":"additional","affiliation":[{"name":"Osaka University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shigeru","family":"Miyagawa","sequence":"additional","affiliation":[{"name":"Osaka University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,7,17]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-5223(19)38510-1"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jtcvs.2014.06.008"},{"issue":"3","key":"e_1_3_4_4_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.
