Tricuspid Valve Surgery: Understanding Your Treatment Options for Tricuspid Regurgitation

Why Tricuspid Regurgitation Deserves Your Attention

For decades, the tricuspid valve was called the "forgotten valve." Cardiologists and surgeons alike focused on the aortic and mitral valves — the left-sided valves that bear higher pressures and tend to cause symptoms earlier. The tricuspid valve, sitting quietly on the right side of the heart, was often left alone, even when it was clearly leaking.

That era is over. We now know that significant tricuspid regurgitation (TR) — a condition where the tricuspid valve fails to close properly, allowing blood to flow backward — carries real consequences. Left untreated, severe TR leads to progressive right heart failure, liver congestion, kidney dysfunction, fluid retention, and reduced survival. Studies published in the Journal of the American College of Cardiology have shown that patients with severe TR who go untreated have significantly worse long-term outcomes compared to those who receive timely intervention.

If you or someone you love has been told they have moderate-to-severe or severe tricuspid regurgitation, this article is written to help you understand what that means, what tricuspid regurgitation treatment options are available, and how to think clearly about the decision ahead.

What Causes Tricuspid Regurgitation — and When Does It Need Treatment?

The tricuspid valve has three thin leaflets that open and close with each heartbeat, ensuring blood moves forward from the right atrium into the right ventricle and then out to the lungs. When those leaflets don't come together properly, blood leaks backward. That leak is tricuspid regurgitation.

Primary vs. Secondary TR

Understanding the cause of your TR matters because it directly affects which TR repair options make sense for you:

• Primary (organic) TR: The valve itself is damaged. Causes include infective endocarditis, rheumatic heart disease, carcinoid syndrome, radiation injury, or trauma — including damage from pacemaker or defibrillator leads that cross through the valve. In these cases, the leaflets are structurally abnormal.
• Secondary (functional) TR: The valve leaflets are structurally normal, but the valve ring (annulus) has dilated — usually because of left-sided heart disease, pulmonary hypertension, or atrial fibrillation. The leaflets simply can't reach each other across the stretched opening. This is by far the more common type, accounting for roughly 80-90% of significant TR cases.

When Treatment Is Warranted

According to the ACC/AHA valvular heart disease guidelines, tricuspid valve surgery should be considered in the following situations:

• Severe TR causing symptoms such as swelling in the legs and abdomen, fatigue, shortness of breath, or liver congestion
• Severe TR in patients already undergoing left-sided valve surgery (this is critically important — I'll explain why below)
• Progressive right ventricular dilation or dysfunction, even if symptoms are mild
• TR caused by pacemaker or defibrillator leads that is severe and symptomatic

One of the most common mistakes I see is waiting too long. By the time a patient has massive TR with severe right heart failure, liver dysfunction, and kidney impairment, the surgical risk has climbed substantially. Early referral and honest assessment of the valve — before the right ventricle is irreversibly damaged — gives patients the best chance at a good outcome.

Tricuspid Valve Surgery: Repair, Replacement, and the Details That Matter

When surgery is indicated, the central question is: can the valve be repaired, or does it need to be replaced? In my experience, this is where the quality of surgical judgment makes the biggest difference in outcomes.

Tricuspid Valve Repair

Repair is preferred whenever it is technically feasible. The most common repair technique for secondary TR is ring annuloplasty — placing a prosthetic ring around the dilated valve annulus to restore its normal size and shape, allowing the leaflets to come together again. This is a well-established, durable approach that avoids the need for a prosthetic valve and the associated risks of anticoagulation or valve degeneration.

Additional repair techniques include:

• Bicuspidization (Kay repair): Plicating one of the three leaflets to convert the valve into a two-leaflet configuration — used selectively in certain anatomies
• Leaflet augmentation with a pericardial patch: When leaflet tissue is insufficient, a patch can be used to extend the leaflet surface area
• Cleft closure or commissuroplasty: Addressing specific structural defects in the leaflets

The success of tricuspid valve repair depends heavily on the underlying cause, the degree of annular dilation, the quality of the leaflet tissue, and — frankly — the surgeon's experience with right-sided valve work. Not every surgeon repairs tricuspid valves regularly. This is one area where asking about case volume is entirely appropriate.

Tricuspid Valve Replacement

When repair is not possible — because the leaflets are destroyed, heavily calcified, or severely tethered — replacement is necessary. Options include:

• Bioprosthetic (tissue) valve: Made from animal tissue (porcine or bovine pericardium). Does not require lifelong blood thinners in most cases. However, tissue valves in the tricuspid position tend to degenerate faster than those on the left side, with studies reporting reoperation rates of 20-30% at 15 years.
• Mechanical valve: Extremely durable but requires lifelong warfarin anticoagulation. Mechanical valves in the tricuspid position carry a higher risk of thrombosis (clotting) compared to left-sided mechanical valves, which makes meticulous anticoagulation management essential.

The choice between bioprosthetic and mechanical replacement in the tricuspid position is nuanced and should be individualized based on your age, life expectancy, ability to manage anticoagulation, and other medical conditions.

The Critical Issue: Tricuspid Repair During Left-Sided Valve Surgery

Here is something every patient undergoing mitral or aortic valve surgery should know: if you have at least moderate TR or a significantly dilated tricuspid annulus (typically greater than 40 mm), the tricuspid valve should be addressed at the same operation. The ACC/AHA guidelines support this as a Class I or Class IIa recommendation.

Why? Because moderate TR frequently progresses to severe TR after left-sided valve surgery. Once that happens, reoperation on an isolated tricuspid valve carries significantly higher mortality — reported in the range of 5-10% or more in the literature, compared to the modest incremental risk of adding a tricuspid annuloplasty during the initial surgery.

I have reviewed cases where surgeons chose not to repair a moderately leaking tricuspid valve during mitral surgery, only for the patient to return years later with severe TR, right heart failure, and a much more dangerous reoperation ahead of them. This is a preventable problem, and it is one of the most important reasons to get a thorough surgical plan reviewed before your operation.

Transcatheter TR Repair Options: The Emerging Frontier

In recent years, catheter-based approaches to tricuspid regurgitation treatment have gained significant traction, particularly for patients considered too high-risk for open surgery. These are performed through veins — without opening the chest — and include:

• Transcatheter tricuspid valve repair (e.g., TriClip/MitraClip for the tricuspid valve): A clip-based device that grasps the tricuspid leaflets to reduce the degree of regurgitation. The TRILUMINATE Pivotal Trial led to FDA approval of the TriClip system in 2023, demonstrating meaningful reduction in TR severity in selected patients.
• Transcatheter tricuspid valve replacement (e.g., EVOQUE, GATE): Investigational devices that implant a new valve within the existing tricuspid annulus via a catheter. Several trials are underway, but these are not yet widely available outside of clinical studies.
• Heterotopic caval valve implantation: Placing valves in the superior and inferior vena cava to reduce backward flow into the veins. This is a bail-out option for patients who are not candidates for direct valve intervention.

Transcatheter tricuspid intervention is promising but still maturing. Patient selection is critical. These devices work best for certain anatomies and certain severities of TR. They are not a replacement for surgical repair in patients who are reasonable surgical candidates — they are an alternative for those who are not.

If you've been told you are "too high-risk" for surgery but have not had your case reviewed by a surgeon experienced in tricuspid valve work, it is worth getting a second opinion before accepting that conclusion.

What to Ask Your Surgeon About Tricuspid Valve Surgery

If tricuspid valve surgery has been recommended — whether as an isolated procedure or combined with other cardiac surgery — you deserve clear answers to these questions:

• What is the cause of my TR? Primary or secondary? Is there an identifiable driver (atrial fibrillation, left-sided valve disease, pulmonary hypertension)?
• Can the valve be repaired, or will it need to be replaced? Ask about the surgeon's repair rate for tricuspid valves specifically.
• How many tricuspid valve operations does this surgeon — and this hospital — perform per year? Volume matters. High-volume centers consistently demonstrate better outcomes for complex valve surgery.
• If I'm having left-sided valve surgery, is the tricuspid valve being addressed? If not, ask why. If you have moderate TR or annular dilation, this warrants a direct conversation.
• Am I a candidate for a transcatheter approach? And if so, is the center experienced in performing these newer procedures?
• What is my estimated operative risk? This should be a specific conversation, not a generic reassurance. Our risk calculator can help you prepare for this discussion.

Making the Right Decision About Tricuspid Regurgitation Treatment

The tricuspid valve may have been "forgotten" by the medical community for too long, but you should not forget it when making decisions about your heart. Severe tricuspid regurgitation shortens lives and erodes quality of life. The good news is that we now have effective surgical and transcatheter tools to treat it — but timing, technique, and surgeon experience make an enormous difference in outcomes.

What I tell my patients is this: the best operation is the right operation, done at the right time, by the right team. That sounds simple, but in practice it requires careful evaluation of your anatomy, your overall health, and the full range of options available to you.

If you have been diagnosed with significant tricuspid regurgitation or told you need tricuspid valve surgery, do not rush — but do not wait indefinitely either. Get your imaging reviewed. Ask hard questions. And if you have any doubt about the plan, seek a second perspective from someone who operates on these valves regularly.
