[Tricuspid annuloplasty--modified technique]

A modification of the DeVega's tricuspid annuloplasty (TAP) in the treatment of tricuspid regurgitation (TR) is described. Using a double-ended 2-0 Ethibond suture buttered with a Teflon felt pledget, a double suture line is begun at the center of the annulus of the anterior tricuspid valve leaflet. The two suture lines 2 to 3 mm apart are run around the edge of the annular ring of the anterior and posterior tricuspid valve leaflets, going over the posteroseptal commissure by 1.5 cm. A tiny piece of Teflon felt is placed at the end of the sutures. The annulus is narrowed to sungly allow passage of a prove with a diameter of 28 or 30 mm. The tricuspid function is assessed by injecting saline into the right ventricle through the right atrium. Between March 1986 and July 1989, 28 patients with functional TR secondary to mitral valve diseases have been operated on by this technique. There are one early and one late deaths, none being related to tricuspid valve annuloplasty. All 26 survivors had a significant drop in right atrial pressure and an associated improvement in clinical status. Follow-up of the 27 patients who survived this TAP ranges from 2 to 38 months (mean 17 months). This annuloplasty is a safe, effective and readily teachable method for the surgical management of TR.
