title: [Unruptured aneurysms of Valsalva sinus of septal origin].
abstract: Aneurysms of Valvsalva sinus unruptured into a cavity, but developing into the membranous and even muscular interventricular septum are exceptional. Two cases illustrating this fact are reported. In one of them, a massive mitral incompetence by elongated chordae tendinae related to the presence of a voluminous intra-septal pouch. Atrio-ventricular and intraventricular conduction disturbances were present in both patients. The interest of supra-valvar angiography which makes it possible to advise operation before the eventual rupture is underlined.
