Abstract:Rev. Bras. Cir. Cardiovasc., 7(2):121-126,1992. RESUMO : O tratamento cirúrgico convencional da estenose aórtica supravalvar caracteriza-se pela ampliação de um ou mais seios de Valsalva, utilizando-se retalhos de material protético, com ou sem secção transversal da aorta. Uma possível limitação dos resultados deste procedimento é o fato do endurecimento ou calcificação do enxerto, dificultando o desenvolvimento da raíz da aorta, mormente quando a cirurgia é realizada em criaças. Para evitar essa complicaç… Show more
“…Sousa et al [5] have reported evolutions in 4-12 years without deaths, with residual gradients ranging from 4.5 to 26 mmHg, mild aortic insufficiency in 76.5% of patients and valve competence in 23.5%.…”

“…In the distal ascending aorta, longitudinal incisions are performed in the three regions corresponding to the commissural posts of the proximal portion of the aorta. The depth of the incisions should be enough for the three protrusions may occupy the distal aortic sinus of Valsalva bottom [5].…”

“…A control echocardiogram showed a maximum instant gradient of 16 mmHg, compatible with the suture line. It is important to stress that there are other techniques that have excellent results without the use of prosthetic material, an extremely important fact for children and in specific situations [2,3].…”

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.
