Overview
Repair annular dilation and reduce pacemaker risk.
The Tri-Ad 2.0 Adams tricuspid band allows the annulus to move throughout the cardiac cycle. Now you can repair annular dilation and preserve 3-D motion during the cardiac cycle while providing free wall support and remodeling. Additionally, due to its large open area, the Tri-Ad 2.0 Adams annuloplasty band delivers industry-low rates of permanent pacemaker implantation.1,2
Product details
Flexible + semi-rigid combined advantage
Flexible remodeling while preserving 3-D motion — the Tri-Ad 2.0 band arms are flexible, whereas semi-rigid remodeling is targeted at the annular dilation.
Tri-Ad 2.0 platform has demonstrated industry-low rates of permanent pacemaker implantation post-tricuspid valve repair.1,2
The wide-open antero-septal aspect helps reduce the risk of potential conduction problems.
- Large open area to minimize conduction risks
- Soft, flexible segments
- Targeted free wall semi-rigid segment

Real-world clinical evidence
Rationale and initial experience with the Tri-Ad Adams tricuspid annuloplasty ring1
In this retrospective study, 42 consecutive patients who underwent concomitant tricuspid repair with the Tri-Ad 2.0 platform were analyzed — predischarge TTE revealed absent or minimal TR in all patients, while no ring-related operative complications were observed. Also, no patient required a permanent pacemaker implantation.
Early Clincal Outcomes of Tricuspid Valve Repair with a Tri-Ad Annuloplasty Ring in Comparison with the Outcomes Using an MC3 Ring2
In this retrospective, single-center study, 36 patients undergoing tricuspid repair with the Tri-Ad 2.0 platform were analyzed. Tricuspid annuloplasty with the Tri-Ad 2.0 platform corrected functional tricuspid regurgitation effectively and provided good early clinical and echocardiographic results without ring-related complications. Specifically, no patient required a permanent pacemaker implantation.
