ObjectivesTricuspid regurgitation (TR) secondary to left heart disease is the most common aetiology of tricuspid valve (TV) insufficiency. Valve annuloplasty is the primary treatment for TV insufficiency. Several studies have shown the superiority of annuloplasty with a prosthetic ring over other repair techniques. We reviewed our experience with different surgical techniques for the treatment of acquired TV disease focusing on long-term survival and incidence of reoperation.MethodsA retrospective analysis of 717 consecutive patients who underwent TV surgery between 1975 and 2009 with either a ring annuloplasty [Group R: N = 433 (60%)] or a De Vega suture annuloplasty [Group NR: no ring; N = 255 (36%)]. Twenty-nine (4%) patients underwent other types of TV repair. A ring annuloplasty was performed predominantly in the late study period of 2000-09. TV aetiology was functional in 67% (479/717) of the patients. Ninety-one percent of the patients (n = 649) underwent concomitant coronary artery bypass grafting and/or mitral/aortic valve surgery.ResultsPatients who received a ring annuloplasty were older (67 ± 13 vs 60 ± 13 years; P < 0.001). Overall 30-day mortality was 13.8% (n = 95) [Group R: n = 55 (12.7%) and Group NR: n = 40 (15.7%)]. Ten-year actuarial survival after TV repair with either the De Vega suture or ring annuloplasty was 39 ± 3 and 46 ± 7%, respectively (P = 0.01). Twenty-eight (4%) patients required a TV reoperation after 5.9 ± 5.1 years. Freedom from TV reoperation 10 years after repair with a De Vega annuloplasty was 87.9 ± 3% compared with 98.4 ± 1% after the ring annuloplasty (P = 0.034).ConclusionsPatients who require TV surgery either as an isolated or a combined procedure constitute a high-risk group. The long-term survival is poor. Tricuspid valve repair with a ring annuloplasty is associated with improved survival and a lower reoperation rate than that with a suture annuloplasty.
