title: [Percutaneous closure of a paravalvular mitral regurgitation with Amplatzer and coil prostheses].
abstract: The authors report a case of percutaneous closure of paravalvular mitral regurgitation in a 9 year old child. This patient had complete atrioventricular canal with levo-isomerism completely repaired with replacement of the left atrioventricular valve by a mechanical prosthesis. One year after an episode of infectious endocarditis, the patient was readmitted because of jaundice due to haemolysis attributed to paravalvular mitral regurgitation. Transoesophageal echocardiography demonstrated a crescent-shaped dehiscence of the prosthesis opposite the left atrial appendage associated with a small paraseptal regurgitation. First of all, a 6 mm Amplatzer Septal Occluder and a 5 x 5 coil were introduced by retrograde catheterisation to treat the regurgitation due to the valve dehiscence. This procedure was completed 3 months later by the implantation of a second 8 mm Amplatzer prosthesis for persistent haemolysis. Closure of the paraseptal regurgitation resulted in a reduction of the patient's transfusional requirements.
