Abstract

Abstract: Annular dilatation is the main mechanism for tricuspid regurgitation, but right ventricular dilatation often adds a restrictive mechanism, which may limit durability. We describe a subvalvular technique anchoring the chordal origins to the annuloplasty, with the aim to stabilize valve geometry and increase durability. A Goretex suture is attached to the anterior papillary muscle. One arm of the suture is stitched through the septal muscle and both arms are atrialized underneath the septal leaflet and tied to the annuloplasty band. In 12 patients (75 ± 6 years, EuroSCORE II 10 ± 9%), severe-torrential tricuspid regurgitation was successfully reduced to mild. Results were stable in all but one patient during follow-up (1–15 months). NYHA class and general health status was improved. This subvalvular technique is safe with the potential to generate a durable repair. Abstract : The main mechanism of tricuspid regurgitation (TR) is tricuspid annular dilatation [1, 2] and treatment generally consists of annuloplasty.
