Mini-loop technique for idiopathic isolated tricuspid valve prolapse: A case report.

We recently performed the mini-loop technique on a 69-year-old woman with idiopathic isolated tricuspid valve prolapse. Although the tricuspid valve leaflets showed no abnormalities, we noted a severely enlarged annulus and posterior leaflet prolapse due to rupture of the posterior papillary muscle. The procedure included four pairs of artificial chordal reconstruction using the loop technique with GORE-TEX® suture CV-4 and the insertion of the 28-mm CE Physio Tricuspid ring. Postoperatively, tricuspid regurgitation was well-controlled below trivial levels. Although the loop technique is typically used in mitral valve plasty, it may also be beneficial for tricuspid valve plasty.
