[Aorto-septal approach (modified Konno procedure). Surgical alternative in the management of diffuse aortic subvalvular stenosis].

The surgical treatment of diffuse subaortic stenosis by insertion of a left ventricular apico-aortic valved conduct and Konno-Rastan procedures often fails to provide satisfactory results. These procedures require the insertion of a prosthetic valve. Some patients with diffuse subaortic stenosis have a normal aortic orifice and the replacement of normal aortic valve is questionable. Since 1984 Vouhé' modification of the Konno' procedure was using this described with adequate relief of the diffuse subaortic stenosis preserving the aortic valve. We present our experience with 5 patients in 10 years was using this surgical alternative.
