Repair of mitral valve and subaortic mycotic aneurysm in a child with endocarditis.

Endocarditis requiring surgical intervention in children is uncommon. Individualized operative therapy must be fashioned to the particular pathology of each case. In this case we describe mitral anterior leaflet homograft patch augmentation valvuloplasty, subaortic homograft patch closure of a large mycotic aneurysm, and homograft aortic root replacement in a 3-year-old patient with endocarditis after remote repair of complete atrioventricular canal.
