Secondary involvement of the mitral valve is well documented in primary aortic valve endocarditis. An important causative mechanism, involving both left-sided valves, is ‘mitral kissing vegetation’. This results from large aortic vegetations prolapsing into the left ventricular outflow tract and “kissing” with the ventricular surface of the anterior mitral leaflet thus causing secondary infection.
