Abstract: 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.
