AbstractAmong our first 11,620 cases of valvular replacement, we observed 285 cases of valvular endocarditis and 59 cases (20.7) in which the importance of the infectious lesions of the aortic or mitral annulus required complex valvular repair.In 23 patients with aortic valvular endocarditis, the presence of an abcess of the aortic annulus required its closure with a patch resulting in one early and one late death and five reinterventions with one death. Twenty patients are alive and well, 1 to 9 years after operation. In 11 patients, the extent of annular abcesses required the insertion of a subcoronary valved conduit. After a maximum follow‐up of 8 years there were two early deaths, two late deaths, one reoperation seven good results. Twelve patients had a supracoronary valved conduit resulting in four early deaths, one late death two reoperations; seven are alive and well, 2 to 6 years later. Three patients previously operated on had a left ventricular abdominal aorta valved conduit, two of them are alive and well up to 6 years later.Severe infectious lesions of the valvular rings (aortic root) can require complex repairs that can be lifesaving and provide excellent long‐term resu
