Background: Functional tricuspid regurgitation (TR) is caused by annular dilatation mainly in the posterior annulus. However, ring annuloplasty does not always prevent the recurrence of TR. Tricuspid repair with 3-dimensional Contour 3D ring is claimed to improve functional TR yet the mid and long-term results of repair need to be assessed.Methods: From March 2013 to March 2015, 50 patients with Functional TR secondary to left-sided valve disease underwent tricuspid annuloplasty using the Contour 3D (Medtronic, Minneapolis, MN) ring. All patients underwent concomitant left-sided valve surgery. Follow-up of TR and right ventricular (RV) function were done before hospital discharge and after 12 and 24 months.Results: Mean ring size was 30.5 mm (range 28–36). Hospital mortality was 4%. The follow-up period was 26 ± 6 months. Echocardiography at hospital discharge documented no or mild, moderate, and moderate to severe TR in 76%, 16% and 4% of the patients respectively. Follow-up after one year revealed mild TR in 16% of patients, moderate TR in 16% patients. At 24 months, moderate TR was present in 12% patients, no patient had any evidence of severe TR at 12 and 24 months. Freedom from TR≥ +3 was 100% after 24 months.Conclusions: Tricuspid annuloplasty with the Contour 3D ring provided satisfactory early results in functional TR which remained stable at mid-term follow up. Still long-term results need further follow up and assessment
