[Unruptured sinus of Valsalva aneurysm. Bi and three-dimensional echocardiography approach].

Aneurysm of the sinus of Valsalva is a rare anomaly that can be congenital or acquire. The most common among the acquire is aortic endocarditis. At the present time echocardiography has be come the election diagnostic method. We present two pediatric patients with unrupture aneurysm of the sinus of Valsalva and cardiac failure secondary to a acute aortic insufficiency manifestations. Transthoracic and transesophageal bidimensional images were compared, in one of them also three-dimensional image. Assessing the quality of images, localization and anatomical morphology of aneurysm, obstruction or compression and presence of associated defects. The usefulness of the three dimensional echocardiography assessment for these congenital malformations is demonstrated.
