Features

Flexible and 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.
  • The Tri-Ad™ 2.0 platform has demonstrated industry-low rates of permanent pacemaker implantation post-tricuspid valve repair.2,3
  • The wide-open antero-septal aspect helps reduce the risk of potential conduction problems.
The Tri-Ad™ 2.0 Adams band offers the largest open area to minimize conduction risks; soft, flexible segments; and targeted free wall semi-rigid segment.

Real-world clinical evidence

Rationale and initial experience with the Tri-Ad™ Adams tricuspid annuloplasty ring2

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 tricuspid regurgitation (TR) in all patients, while no ring-related operative complications were observed. Also, no patient required a permanent pacemaker implantation.

Early clinical outcomes of tricuspid valve repair with a Tri-Ad™ annuloplasty ring in comparison with the outcomes using an MC3 ring3

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.

Key risks of tricuspid annuloplasty include recurrent regurgitation, stenosis, and ring dehiscence.

Accessory enhancements

The Tri-Ad™ 2.0 holder offers end-to-end support, clearly marked implant size, visible semi-saddle aspect, and two prominent cut points.

Tri-Ad™ 2.0 holder

  • End-to-end support with full edge accessibility for suturing
  • High-visibility white with clearly marked implant size
  • Visible semi-saddle aspect to accommodate the tricuspid annulus saddle
  • Two prominent cut points that are easily visible and accessible4
The Tri-Ad™ 2.0 sizer is transparent with a product pictogram for clear visualization of coverage and orientation, is designed with commissural recesses to avoid snagging, and a hole to facilitate the use of a suture tag.

Tri-Ad™ 2.0 sizer

  • Transparent with product pictogram for visualization of coverage and orientation
  • Available in six sizes: 26, 28, 30, 32, 34, and 36 mm
  • Added commissural recesses that are designed to avoid snagging of sutures
