Summary
A continuous suture technique for tricuspid ring annuloplasty effectively corrects tricuspid regurgitation (TR) and reduces right atrial size and pressure. This method offers a simpler alternative to traditional interrupted sutures for TR repair.
Area of Science:
- Cardiovascular Surgery
- Cardiac Valve Repair
- Surgical Techniques
Background:
- Tricuspid regurgitation (TR) correction traditionally involves multiple interrupted sutures for ring annuloplasty.
- This poses a challenge in securing the ring prosthesis to the tricuspid annulus.
Purpose of the Study:
- To evaluate the efficacy of a continuous suture technique for tricuspid ring annuloplasty.
- To compare this novel method with the standard interrupted suture technique for TR correction.
Main Methods:
- A continuous 2-0 polypropylene suture was used for tricuspid ring annuloplasty in 20 patients.
- The procedure was performed using a Duran flexible ring prosthesis, often concomitantly with left-sided cardiac procedures.
Main Results:
- No perioperative mortality or conduction issues were observed.
- Significant improvement in TR was noted, with moderate to severe TR reduced to mild.
- Post-procedure, right atrial volume decreased (123.7±69.2 mL to 74.5±37.4 mL) and mean right atrial pressure lowered (18.7±12.2 mmHg to 8.9±5.5 mmHg).
Conclusions:
- Continuous "over and over" suturing is a viable and effective method for tricuspid ring annuloplasty.
- This technique facilitates secure ring fixation and intentional annular placation, simplifying TR repair.
