In a significant shift within cardiac care, the tricuspid valve, once overlooked, is gaining renewed attention with the advent of expanded therapy options. The tricuspid valve, a critical component of the heart's anatomy, is at the forefront of medical advancements that promise better patient outcomes. Recent studies, including the TRILUMINATE and TRISCEND II trials, highlight the effectiveness of new devices that have revolutionized the treatment landscape for tricuspid valve regurgitation. As clinicians and researchers continue to explore both surgical and percutaneous interventions, the need for long-term follow-up studies becomes imperative to validate these promising therapies.
The tricuspid valve, historically known as the "forgotten valve," is receiving newfound appreciation in light of innovative treatment options. The first surgical intervention for tricuspid regurgitation was conducted nearly 60 years ago, yet isolated regurgitation procedures have remained uncommon due to high in-hospital mortality rates. However, recent data suggests that surgery should no longer be dismissed for patients with severe tricuspid regurgitation. New evidence demonstrates that surgical interventions carry an acceptable risk and exhibit good durability after the acute postoperative period.
Isolated tricuspid valve operations now show a reasonable benefit-to-risk ratio, supported by a risk model derived from the recently published Society of Thoracic Surgeons (STS) tricuspid repair data. This model has been instrumental in reassessing the operative risk and durability of such procedures. Despite previous hesitations, these surgeries are proving beneficial for patients who might otherwise face a daunting 1-year mortality rate of nearly 40% if left untreated.
The TRILUMINATE trial marks a pivotal moment in tricuspid valve repair history, showcasing that the use of the TriClip G4 device achieved superior outcomes compared to traditional medical therapy within just 30 days. Similarly, the TRISCEND II trial demonstrated that the EVOQUE transcatheter tricuspid valve replacement system outperformed medical therapy at the 1-year mark. Both devices received approval in 2024, marking a new era in the management of tricuspid valve disease.

A follow-up period of 3-5 years is necessary to fully understand the relative durability of percutaneous versus surgical repairs of the tricuspid valve. Such longitudinal studies are essential as they provide clearer insights into the long-term efficacy and safety of these interventions. As data matures, it becomes increasingly evident that both surgeons and interventionalists have crucial roles in advancing the field of tricuspid valve repair.
The impaired tricuspid valve poses a significant health challenge that warrants comprehensive attention. With new treatment modalities emerging, clinicians are tasked with making informed management decisions to optimize patient outcomes. The evolving landscape presents opportunities for enhanced collaboration between surgeons and interventionalists, fostering innovation and improved therapeutic strategies.

Patients suffering from severe tricuspid regurgitation often experience debilitating symptoms that significantly impact their quality of life. The development and approval of cutting-edge devices like TriClip G4 and EVOQUE transcatheter systems offer hope for these individuals. These advancements not only aim to reduce mortality rates but also strive to enhance patients' overall well-being.
The journey towards effective tricuspid valve repair has been marked by both challenges and breakthroughs. While isolated procedures were previously avoided due to associated risks, current evidence underscores their potential benefits. Moreover, the creation of risk models has been pivotal in guiding surgical decision-making, ensuring that patients receive tailored treatments that align with their specific needs.
