[Rupture of a sinus of Valsalva aneurysm in the left atrium]. / Rupture d'un anévrisme des sinus de Valsalva dans l'oreillette gauche.

Ruptures of sinus of Valsalva aneurysms are a rare complication, and very few cases of rupture in the left atrium have been described. In this clinical case we report the case of a patient hospitalised with a scenario of cardiac insufficiency revealing a very large posterior sinus of Valsalva aneurysm, associated with a bicuspid aortic valve, and rupture in the left atrium. The diagnosis was by transthoracic and transoesophageal multiplan echocardiography, and the treatment surgical, with a good result.
