Abstract:
Rapid progression of valvular stenosis in the setting of infective endocarditis is extremely rare. Here we describe a patient with Bartonella endocarditis on a bioprosthetic aortic valve that caused rapidly progressive aortic stenosis without regurgitation. At operation the bioprosthetic valve was severely fibrotic and calcified, with markedly thickened and distorted leaflets and circular partial detachment from the aortic ring. The patient underwent aortic root replacement with aortic bioprosthesis and aortic grafting with reimplantation of the coronary ostia.
