[Vegetations of the mitral valve and the mitral prosthesis in patients with subacute bacterial endocarditis. Echocardiographic diagnosis].

In a patient with SBE in three differents ocassions in a period approximately of 9 months, the mitral valve was replaced on two occasions. The echocardiogram detected vegetations on two ocassions. The diagnosis of vegetation at the level of the mitral valve, was done for the first time in our hospital by this method. During the last admission, the echocardiogram suggested a vegetation at the level of the artificial mitral valve, projecting into the left atrium with the systole. This was confirmed by surgery.
