Key result
Continuous suture tricuspid annuloplasty is linked to ~40% reduction in right atrial volume.
Why the study?
Tricuspid ring annuloplasty typically requires many interrupted mattress sutures, and the efficacy of a continuous suture technique for ring implantation was evaluated.
Does a continuous 'over and over' suture technique for tricuspid ring annuloplasty improve tricuspid regurgitation and right atrial parameters in patients with tricuspid regurgitation?

Does a continuous 'over and over' suture technique for tricuspid ring annuloplasty improve tricuspid regurgitation and right atrial parameters in patients with tricuspid regurgitation?
Absolute Event Rate: 74.5% vs 123.7%
p-value: p=<0.05
A continuous 'over and over' suture technique for tricuspid ring annuloplasty is safe and effectively reduces tricuspid regurgitation and right atrial dimensions.
Supports feasibility of continuous suture tricuspid annuloplasty; hypothesis-generating and requires randomized comparison.
BACKGROUND: A ring implantation in the tricuspid annulus requires many interrupted mattress sutures for correction of tricuspid regurgitation (TR). In this study, tricuspid ring annuloplasty was performed by 2-0 polypropylene continuous suture instead of multiple interrupted 2-0 polyester mattress sutures, and the efficacy of the method was evaluated. MATERIALS AND METHODS: This study included 20 patients who underwent tricuspid ring annuloplasty by continuous suture between May 2009 and July 2010. Four of the patients had an isolated TR, and the rest had a left-sided cardiac lesion. The concomitant tricuspid annuloplasty was performed after the left-sided heart surgery was completed and a Duran flexible ring prosthesis was used. RESULTS: There was no perioperative mortality or conduction problem. More than a moderate degree of TR was improved to less than a mild degree after the procedure. After the ring annuloplasty, the right atrial volume decreased from 123.7±69.2 mL to 74.5±37.4 mL, and the mean right atrial pressure was lowered from 18.7±12.2 mmHg to 8.9±5.5 mmHg. CONCLUSION: The continuous "over and over" suture may be a useful procedure for fixing the ring to the annulus and making an intentional annular placation in performing tricuspid ring annuloplasty.

Park et al. (2012) conducted an observational in Functional tricuspid valve regurgitation (n=20). Tricuspid ring annuloplasty using a continuous 'over and over' suture technique vs. Baseline (preoperative values) was evaluated on Right atrial volume (mL) (p=<0.05). Tricuspid ring annuloplasty using a continuous suture technique safely reduced right atrial volume from 123.7 mL to 74.5 mL and improved tricuspid regurgitation to less than mild.
