[Congenital left sinus of Valsalva aneurysm]. / Aneurisma congênito do seio de Valsalva esquerdo.

ABSTRACT

Two cases of left sinus of Valsalva congenital aneurysm (SVCA), incidentally found are described. The authors call attention on rarity of them, and present new concepts about their morphogenesis and incidence. They also suggested a higher incidence of asymptomatic and undiagnosed cases of SVCA should be considered.
