[Treatment of functional tricuspid insufficiency by a valvuloplasty with a flexible linear reducer]

Valvuloplasty with preservation of the valvular apparatus is the treatment of choice in functional tricuspid incompetence (FTI). A new method of valvuloplasty has been developed using a flexible linear reducer (FLR); its insertion is simple and without risk to the Bundle of His. It is made of sections of elastomere covering a dacron core. The principle of the FLR is reduction of the tricuspid annulus leaving the septal leaflet free. It is a simple method which allows individual variations in the zone reduced (usually involving the anterior and inferior leaflets) and in the size of the reduction at each point. The excellent results at medium term in 20 patients with tricuspid FLR lead us to recommend widening the surgical indications for correction of FTI especially in cases where signs of right ventricular failure have been observed.
