Endocarditis with massive aortic root abscess and atrioventricular septal destruction.
Endocarditis involving the aortic root and intervalvular fibrous skeleton presents a reconstructive dilemma. We report a case of endocarditis involving the aortic root and tricuspid valve with extensive destruction of the atrioventricular septum. Debridement necessitated resection of the aortic root, aortic valve, tricuspid valve, and a large portion of atrioventricular septum, leaving the right atrium, right ventricle, left ventricle and aorta in open communication. Reconstruction was accomplished by separating the left and right hearts with a Dacron patch, tricuspid valve replacement, and aortic root replacement. Proper planar localization of the aortic root was necessary to avoid left ventricular outflow obstruction and coronary torsion.
