Kurzfassung:
About half of tricuspid valves (TVs) have 2 posterior leaflets, and the fibrous tissue of the tricuspid annulus is poor. Considering the anatomy and histology of the TV, we devised a secure ring annuloplasty technique. We herein report the outcomes of our continuous wrapping suture annuloplasty technique using a flexible total ring. Methods: We used a Tailor™ ring (Abbott, Chicago, IL, USA) as a full ring. The mark on the left side of the ring was fixed to the anteroseptal commissure, and the midpoint of the ring’s markers was fixed at the center of the septal leaflet annulus. Using a continuous suture, all stitches were passed around the annuloplasty ring without penetration. One suture from the anteroseptal commissure ran toward the left side and another from the midpoint of the septal leaflet annulus ran toward the right, leading to annuloplasty without TV deformation. Results: Eighty patients underwent TV repair with this technique. The tricuspid regurgitation (TR) score in all patients improved from 1.9 ± 0.7 to 0.8 ± 0.4 ( P 〈 0.001) at 3 years postoperatively. The TR score of TVs with 2 posterior leaflets also improved from 1.9 ± 0.7 to 0.6 ± 0.4 after the operation and was unchanged during follow-up. The median follow-up period was 1.3 (0.5 to 2.0) years, and no patients required TV reoperation. The 3-year survival rate was 93%, and the 3-year rate of freedom from pacemaker implantation was 95%. Conclusions: The continuous wrapping suture technique using a flexible total ring is a useful procedure without TV deformation even when 2 posterior leaflets are present.
