We present a 16-year-old male with borderline left ventricular systolic function and biventricular diastolic dysfunction who developed transient severe biventricular failure immediately following Amplatzer Septal Occluder (Abbott, Plymouth, MN, USA) deployment. Preprocedural echocardiography revealed right ventricular dilation, a D-shaped septum in diastole. Intraprocedural haemodynamic assessment demonstrated elevated right ventricular diastolic pressures (right ventricular minimal diastolic pressure: 11 mmHg; end-diastolic pressure: 17 mmHg). Haemodynamic collapse occurred within minutes of device release, necessitating emergent dopamine infusion and urgent coronary angiography to rule out device-related complications. Remarkably, ventricular function normalised within 2 hours, enabling extubation the same day. Reports of transient biventricular failure following atrial septal defect closure in adolescents without comorbidities are exceedingly rare, underscoring the critical role of preexisting diastolic dysfunction in precipitating acute decompensation. This case advocates for preprocedural balloon occlusion testing and vigilant haemodynamic monitoring in adolescents with impaired ventricular compliance to mitigate catastrophic outcomes.<\/jats:p>","DOI":"10.1017\/s1047951125110524","type":"journal-article","created":{"date-parts":[[2026,1,29]],"date-time":"2026-01-29T11:16:28Z","timestamp":1769685388000},"page":"187-190","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":1,"title":["Transient biventricular collapse after atrial septal defect closure in an adolescent: a diastolic dysfunction-driven paradox"],"prefix":"10.1017","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7046-8571","authenticated-orcid":false,"given":"Utku","family":"Pamuk","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/033fqnp11","id-type":"ROR","asserted-by":"publisher"}],"name":"Ankara Bilkent City Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7841-1331","authenticated-orcid":false,"given":"Emine","family":"Azak","sequence":"additional","affiliation":[{"name":"University of Health Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2026,1,29]]},"reference":[{"key":"S1047951125110524_ref7","doi-asserted-by":"publisher","DOI":"10.1067\/mtc.2001.115424"},{"key":"S1047951125110524_ref10","first-page":"401","article-title":"Improvement in cardiac structure and functions early after transcatheter closure of secundum atrial septal defect in children and adolescents","volume":"55","author":"Y\u0131lmazer","year":"2013","journal-title":"Turk J Pediatr"},{"key":"S1047951125110524_ref3","doi-asserted-by":"publisher","DOI":"10.1136\/hrt.18.2.209"},{"key":"S1047951125110524_ref1","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9149(01)02134-8"},{"key":"S1047951125110524_ref6","doi-asserted-by":"publisher","DOI":"10.1016\/j.cardfail.2011.07.003"},{"key":"S1047951125110524_ref4","doi-asserted-by":"publisher","DOI":"10.1016\/0735-1097(88)92605-8"},{"key":"S1047951125110524_ref11","doi-asserted-by":"publisher","DOI":"10.1186\/s43044-020-00120-x"},{"key":"S1047951125110524_ref2","doi-asserted-by":"publisher","DOI":"10.1152\/ajplegacy.1946.145.4.458"},{"key":"S1047951125110524_ref5","doi-asserted-by":"publisher","DOI":"10.1253\/jcj.60.758"},{"key":"S1047951125110524_ref8","doi-asserted-by":"crossref","first-page":"638","DOI":"10.5543\/tkda.2013.63295","article-title":"Heart failure after transvenous closure of atrial septal defect associated with atrial standstill and thiamine-responsive megaloblastic anemia","volume":"41","author":"Do\u011fan","year":"2013","journal-title":"Turk Kardiyol Dern Ars"},{"key":"S1047951125110524_ref9","doi-asserted-by":"publisher","DOI":"10.21037\/jtd.2018.02.80"}],"container-title":["Cardiology in the Young"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S1047951125110524","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,10]],"date-time":"2026-04-10T04:34:29Z","timestamp":1775795669000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S1047951125110524\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,1]]},"references-count":11,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2026,1]]}},"alternative-id":["S1047951125110524"],"URL":"https:\/\/doi.org\/10.1017\/s1047951125110524","relation":{},"ISSN":["1047-9511","1467-1107"],"issn-type":[{"value":"1047-9511","type":"print"},{"value":"1467-1107","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,1]]},"assertion":[{"value":"\u00a9 The Author(s), 2026.
