Few TRAP sequence cases have a rudimentary heart with cardiac motion in the acardiac twins. Herein, we investigated the venous Doppler waveform in two cases of TRAP sequence with a rudimentary heart with cardiac motion in the acardiac twin. Although both cases had veno-venous anastomoses, the venous Doppler waveforms of the umbilical vein differed. A comparison of the characteristics of the cases indicated that the existence of a ductus venosus, or greater heart pulse power, in the acardiac twin might impact the venous Doppler waveform in the pump twin.<\/jats:p>","DOI":"10.1017\/thg.2022.16","type":"journal-article","created":{"date-parts":[[2022,5,13]],"date-time":"2022-05-13T11:06:59Z","timestamp":1652440019000},"page":"85-88","source":"Crossref","is-referenced-by-count":3,"title":["Doppler Waveform Analysis of Intertwin Venous Blood Flow in Twin Reversed Arterial Perfusion (TRAP) Sequence with a Rudimentary Heart"],"prefix":"10.1017","volume":"25","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6909-8294","authenticated-orcid":false,"given":"Hiroko","family":"Konno","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takeshi","family":"Murakoshi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2022,5,13]]},"reference":[{"key":"S1832427422000160_ref2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469-0705.1999.14060422.x"},{"key":"S1832427422000160_ref5","doi-asserted-by":"publisher","DOI":"10.1002\/pd.5710"},{"key":"S1832427422000160_ref3","doi-asserted-by":"publisher","DOI":"10.1046\/j.1469-0705.1999.14060375.x"},{"key":"S1832427422000160_ref4","first-page":"285","article-title":"Twin reversed arterial perfusion (TRAP) sequence: A study of 14 twin pregnancies with acardius","volume":"7","author":"van Allen","year":"1983","journal-title":"Seminars in Perinatology"},{"key":"S1832427422000160_ref1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9378(94)90308-5"}],"container-title":["Twin Research and Human Genetics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S1832427422000160","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,6,20]],"date-time":"2022-06-20T10:34:35Z","timestamp":1655721275000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S1832427422000160\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,4]]},"references-count":5,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2022,4]]}},"alternative-id":["S1832427422000160"],"URL":"https:\/\/doi.org\/10.1017\/thg.2022.16","relation":{},"ISSN":["1832-4274","1839-2628"],"issn-type":[{"value":"1832-4274","type":"print"},{"value":"1839-2628","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,4]]}}}
