Predictable correction of tricuspid insufficiency by semicircular annuloplasty

During surgical correction of multivalvular lesions, acquired tricuspid insufficiency is best treated by a semicircular annuloplasty technique. In order to achieve an individualized and accurate correction, the tricuspid annuloplasty suture is tied around an obturator, the dimensions of which are based upon Carpentier's tricuspid ring.
