The areas under the receiver operating characteristic curve (AUC) for HPF were 0.92 for PV, 0.99 for NV, and 0.99 for VR; the velocity thresholds were 2.47, 1.15, and 0.45\u00a0m\/sec, respectively. For LPF, the AUCs were 0.63 for PV, 0.78 for NV, and 0.81 for VR, and the velocity thresholds were 2.70, 1.59, and 0.58\u00a0m\/sec, respectively; thus, VR best indicated band tightness. In part B, we performed BPAB in 34 patients, adjusting the bands to achieve VRs between 0.45 and 0.58. The prevalence of HPF was significantly lower in part B than in part A, whereas those of LPF did not differ.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In BPAB, we consider the optimal range of VR at banding site is between 0.45 and 0.58.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1007\/s11748-025-02156-9","type":"journal-article","created":{"date-parts":[[2025,5,14]],"date-time":"2025-05-14T05:44:59Z","timestamp":1747201499000},"page":"811-818","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Intraoperative echocardiographic indicator for optimal bilateral pulmonary artery banding"],"prefix":"10.1007","volume":"73","author":[{"given":"Tetsuri","family":"Takei","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0582-6349","authenticated-orcid":false,"given":"Yukihiro","family":"Kaneko","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryoichi","family":"Kondo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naho","family":"Morisaki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ikuya","family":"Achiwa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2025,5,14]]},"reference":[{"issue":"6","key":"2156_CR1","doi-asserted-by":"publisher","first-page":"1984","DOI":"10.1016\/j.jtcvs.2014.01.042","volume":"147","author":"Y Kaneko","year":"2014","unstructured":"Kaneko Y, Achiwa I, Morishita H, Shibata M.
