[Aortic valve replacement in infectious destruction of the aortic annulus. A new technic].

The results of aortic valve replacement in the acute phase of valvular endocarditis are dependent upon the degree of destruction by sepsis of the left ventricle-aorta junction. The stability of the prosthesis installed is conditioned by the extent of the lesion. Numerous techniques have been described to maintain the prosthesis firmly in place. In the technique reported here, the prosthesis is implanted in the usual position, but the sutures are tied outside the heart. Depending on the site of the lesion, this is done by opening the left atrium or the infundibulum of the right ventricle, and by passing the stitches through the aortic wall. This quick and simple technique ensures good stability of the prosthesis.
