[Aneurysm of the sinistro-anterior sinus of Valsalva causing coronary insufficiency. Apropos of a case].

The aneurysm of the sinistro-anterior sinus of Valsalva (ASASV) can very rarely be disclosed by symptoms of coronary insufficiency. The authors report the case of a 73 old man suffering from unstable angina pectoris, in whom the diagnosis of ASASV was evoked by two-dimensional echocardiography and confirmed by aortography. Coronary angiography revealed an external compression of IVA by the ASASV and allowed to exclude the presence of associated autonomous coronaropathy. The interest of this observation lies in the fact that the preoperative diagnosis was made after the two-dimensional echocardiography allowing the evaluation of the importance and volume of the ASASV. Aortography and coronary angiography are indispensable procedures in the presence of chest pain suspect of coronary insufficiency. These investigations will guide the surgical treatment which should always associate a closure of the aneurysmal neck, an aortic valvular replacement and a bypass of the compressed coronary artery.
