Through comparison to transthoracic echocardiography (Echo), the accuracy of EC has been verified. However, left-to-right patent ductus arteriosus (PDA) shunting is a concern because PDA shunts aortic flow to the pulmonary artery and may interfere with EC in measuring CO. <b><i>Objective:<\/i><\/b> To determine the agreement between EC and Echo in preterm infants with a hemodynamically significant PDA (hsPDA). <b><i>Methods:<\/i><\/b> We reviewed our hemodynamic database in which simultaneous CO measurements by Echo and EC (Aesculon\u00ae) were recorded. Preterm infants with left-to-right shunting hsPDA were enrolled. <b><i>Results:<\/i><\/b> A total of 105 paired measurements in 36 preterm infants were compared. Infants' median (range) age and weight at measurement were 27<sup>+2<\/sup> weeks (24<sup>+0<\/sup>-33<sup>+1<\/sup>) and 1,015 g (518-1,880), with mean (95% CI) ductal diameter 2.11 mm (1.99-2.22) or 2.15 mm\/kg (2.00-2.30). Mean CO<sub>EC<\/sub> and CO<sub>Echo<\/sub> were 252 \u00b1 32 and 258 \u00b1 45 mL\/kg\/min, respectively, which demonstrated a moderate correlation and without a significant between-measurement difference. Bland-Altman analysis showed a bias, limits of agreement, and error percentage of -5.3 mL\/kg\/min, -78.3 to 67.7 mL\/kg\/min, and 28.6%, respectively. There was a trend of increased bias and error percentage of infants with high CO \u2265280 mL\/kg\/min and supported with high-frequency ventilator. <b><i>Conclusions:<\/i><\/b> EC and Echo have a wide but clinically acceptable agreement in measuring CO in preterm infants with hsPDA. However, for infants with high CO or ventilated by high-frequency ventilation, interpretation of CO<sub>EC<\/sub> should be approached with caution.<\/jats:p>","DOI":"10.1159\/000475774","type":"journal-article","created":{"date-parts":[[2017,7,13]],"date-time":"2017-07-13T17:01:29Z","timestamp":1499965289000},"page":"231-237","source":"Crossref","is-referenced-by-count":34,"title":["Electrical Cardiometry to Monitor Cardiac Output in Preterm Infants with Patent Ductus Arteriosus: A Comparison with Echocardiography"],"prefix":"10.1159","volume":"112","author":[{"given":"Kai-Hsiang","family":"Hsu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tai-Wei","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I-Hsyuan","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mei-Yin","family":"Lai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shih-Yun","family":"Hsu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hsiao-Wen","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tze-Yee","family":"Mok","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reyin","family":"Lien","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2017,7,14]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1177\/1089253210386386"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1586\/erd.12.32"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.earlhumdev.2010.01.032"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1097\/00044067-199908000-00008"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1136\/fetalneonatal-2011-301090"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1007\/s00134-012-2530-3"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.3389\/fped.2014.00016"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1055\/s-0034-1371707"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1186\/s13054-014-0603-0"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1038\/jp.2014.245"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1007\/s00431-014-2437-9"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1055\/s-0034-1543981"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2015-0368"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1038\/jp.2016.2"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1016\/0378-3782(89)90013-3"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1136\/adc.2003.027698"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1080\/10543400701329422"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1186\/cc7129"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1038\/jp.2016.65"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1136\/fn.82.3.F182"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1097\/00003246-200001000-00038"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1007\/s00134-003-1967-9"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1186\/s12968-014-0054-4"}],"container-title":["Neonatology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/475774","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/475774","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T12:23:15Z","timestamp":1745410995000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000475774"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017]]},"references-count":23,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2017,10,6]]}},"URL":"https:\/\/doi.org\/10.1159\/000475774","archive":["Portico"],"relation":{},"ISSN":["1661-7800","1661-7819"],"issn-type":[{"value":"1661-7800","type":"print"},{"value":"1661-7819","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017]]}}}
