Echocardiography was performed before laser surgery to detect the presence of PS\/PA. The outcomes of recipients with and without PS\/PA were compared. The need of postnatal cardiac interventions and the survival rate at 6 months of age were also evaluated. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; PS was observed in 16\/260 (6.2%) of recipient twins and PA in 12\/260 (4.6%). After fetal surgery, 10\/28 (35.7%) recipients died, 9\/28 (32.1%) showed in utero regression, and 9\/28 (32.1%) had persistence of PS\/PA. Postnatally, seven recipients underwent percutaneous balloon pulmonary valvuloplasty, one required surgical valvotomy and one palliative surgery. Pregnancies with recipient twins with PS\/PA had lower survival of at least one twin (67.9 vs. 83.6%, p = 0.045) and lower overall survival (57.1 vs. 72.8%, p = 0.015) at 6 months of age. &lt;b&gt;&lt;i&gt;Conclusion:&lt;\/i&gt;&lt;\/b&gt; PS and PA were observed in 10.8% of recipients. Among these, about one third showed persistence of pulmonary valve pathology after delivery, which stresses the need for strict follow-up.<\/jats:p>","DOI":"10.1159\/000448075","type":"journal-article","created":{"date-parts":[[2016,7,25]],"date-time":"2016-07-25T21:01:29Z","timestamp":1469480489000},"page":"191-196","source":"Crossref","is-referenced-by-count":21,"title":["Rate and Outcomes of Pulmonary Stenosis and Functional Pulmonary Atresia in Recipient Twins with Twin-Twin Transfusion Syndrome"],"prefix":"10.1159","volume":"41","author":[{"given":"Javier U.","family":"Ortiz","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Narc\u00eds","family":"Masoller","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olga","family":"G\u00f3mez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mar","family":"Bennasar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elisenda","family":"Eixarch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silvia M.","family":"Lobmaier","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F\u00e0tima","family":"Crispi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eduard","family":"Gratacos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Josep Mar\u00eda","family":"Martinez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2016,7,26]]},"container-title":["Fetal Diagnosis and Therapy"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/448075","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/448075","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T16:59:29Z","timestamp":1745427569000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000448075"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016,7,26]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2017,4,26]]}},"URL":"https:\/\/doi.org\/10.1159\/000448075","archive":["Portico"],"relation":{},"ISSN":["1015-3837","1421-9964"],"issn-type":[{"value":"1015-3837","type":"print"},{"value":"1421-9964","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016,7,26]]}}}
