Rupture of giant aneurysm of sinus of Valsalva usually requires surgery to prevent life-threatening
complications from occurring. We report the case of a 55-year-old patient with a previous history of aortic
valve replacement who was urgently referred to our institution with a superior vena cava syndrome and
dyspnea. CT-scan initially misdiagnosed a dissection of the aortic root that was ultimately a contained
rupture of a giant aneurysm of the non-coronary sinus of Valsalva. Despite a sudden hemodynamic
deterioration with a collapse and cardiac arrest, urgent salvage surgery was successfully performed with an
uneventful outcome. Physiopathogeny of hemodynamic profiles influencing immediate survival and
surgical technique are discussed in this report.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
