[Tricuspid valve replacement in the true annulus of Ebstein's anomaly without involvement of atrioventricular conduction disturbance].
Two female patients with Ebstein's anomaly, aged 12 and 45 years, underwent new procedures of tricuspid valve replacement in the true annulus without involvement of atrioventricular conduction disturbance. The first patient had a relatively small atrialized right ventricle. A Dacron patch was sutured on the atrialized portion from the right ventricular side. Buttress stitches were placed on the whole of the atrialized ventricle except at the part of the His' bundle. A porcine valve was sutured in the true annulus of the tricuspid valve and on the top of the patch. The second patient had a fairly large atrialized ventricle, and plication was made only in the inferior part of the atrialized ventricle form the coronary sinus. A porcine valve was sutured in the true tricuspid annulus except at the part of Koch's triangle, where the porcine valve was placed on the false annulus.
