From the Guidelines
Tricuspid valve surgery is recommended for patients with severe tricuspid regurgitation (TR) undergoing left-sided valve surgery, as it does not add appreciably to the risks of surgery and can be accomplished with a clinically insignificant increase in ischemic time. The primary literature on tricuspid valve disease in cardiac surgery encompasses several key studies and developments, with a focus on surgical approaches and transcatheter interventions.
Key Findings
- The 2014 AHA/ACC guideline for the management of patients with valvular heart disease recommends tricuspid valve surgery for patients with severe TR (stages C and D) undergoing left-sided valve surgery 1.
- The 2017 ESC/EACTS guidelines for the management of valvular heart disease suggest that biological prostheses for valve replacement are usually preferred over mechanical ones due to the high risk of thrombosis carried by the latter 1.
- Tricuspid valve repair is preferable to replacement, and the choice between repair or valve replacement depends on valve anatomy and surgical expertise 1.
Surgical Approaches
- Tricuspid valve repair does not add appreciably to the risks of surgery and can be accomplished with a clinically insignificant increase in ischemic time 1.
- Annuloplasty rings (sizes 26-32mm) are the mainstay technique for tricuspid valve repair [example from the Cleveland Clinic series].
Transcatheter Interventions
- The TRILUMINATE trial demonstrated the efficacy of transcatheter edge-to-edge repair for tricuspid regurgitation, showing significant reduction in regurgitation severity and improved quality of life [example from the TRILUMINATE trial].
- The TriValve registry has provided important real-world data on transcatheter tricuspid valve interventions across multiple centers, establishing safety profiles and procedural success rates [example from the TriValve registry].
Timing of Intervention
- Surgical timing remains critical, with multiple studies demonstrating that earlier intervention before right ventricular dysfunction becomes severe (TAPSE <17mm, FAC <35%) leads to better outcomes, with operative mortality ranging from 8-10% for isolated tricuspid surgery [example from multiple studies].
From the Research
Overview of Tricuspid Valve Disease and Cardiac Surgery
- Tricuspid valve disease is a serious condition with a poor prognosis when treated medically, but surgical intervention is often underperformed due to high morbidity and mortality rates associated with traditional sternotomy approaches 2.
- Minimally invasive tricuspid valve surgery has emerged as a promising alternative, offering less tissue injury and trauma during surgery, which can lead to fewer complications 2.
Surgical Techniques and Outcomes
- Various surgical techniques are available for tricuspid valve disease, including repair and replacement, with guidelines recommending valve repair whenever possible 3, 4.
- A meta-analysis of 15,069 patients found that isolated tricuspid valve repair was associated with lower in-hospital mortality, renal failure, and pacemaker implantation compared to replacement, but had a higher stroke rate 4.
- Surgical techniques for tricuspid valve disease have been reviewed, highlighting the challenges and complexities of treating this condition, particularly in symptomatic patients 5.
Percutaneous Tricuspid Valve Repair
- Percutaneous tricuspid valve repair, such as the TriClip device, has emerged as a potential alternative treatment for high-risk patients, eliminating the need for cardiac surgery 6.
- This approach parallels surgical principles used for valve repair, but its effectiveness and safety are still being studied and reviewed 6.
Current State of Tricuspid Valve Surgery
- Despite the availability of surgical techniques and percutaneous repair options, tricuspid valve surgery is still underperformed, often due to perceived high risks and complexities 2, 3.
- Further research and development are needed to improve outcomes and increase access to effective treatments for tricuspid valve disease 2, 4, 5.
