Abstract
|
|
|
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.
