Infectious endocarditis is a serious complication in patients with valve diseases and sometimes presents technical difficulties for its treatment. One of those situations concerns prosthesis dysfunctions placed in aortic position or of natural aortic valves, in which endocarditis causes partial descontinuity between the left ventricle and the aorta by the lesion of the continuity of the mitral-aortic or of the muscular septum. In the Instituto Dante Pazzanese de Cardiologia we operated three patients with closed abscesses but with a great separation between the left ventricle and the aorta in which the fixation of the prosthesis couldn't be done by the usual technique nor by the suspension of the anterior mitral leaflet. We reestablished continuity between the left ventricle and the aorta using a patch of bovine paricardium and attaching part of the prosthesis to the preserved valvar ring and the other part in a ring created by the mattress sutures passed in the implanted pericardium. One patient died with 26 days post-surgery due to pulmonary emboly. The other two were discharged and are without symptoms at 14 and 4 months of evolution. The last one has a slight aortic reflux.
