Tricuspid Valve Surgery

Tricuspid valve surgery is performed by a cardiovascular surgeon to treat congenital tricuspid valve disease, tricuspid valve stenosis, and tricuspid valve regurgitation. Disease tricuspid valves are repaired or replaced. The decision for repair vs. replacement is based on:
• Diagnostic test results (echocardiogram and cardiac catheterization)
• Heart structure and anatomy
• The patient’s age
• The presence of other medical conditions

Indications for Tricuspid Valve Surgery
Early surgical intervention (for valve repair in particular) may prevent irreversible heart damage. The decision about timing for elective (non-emergency) valve surgery is made between a patient and his or her doctor and is based on comparing the risk of surgery with the benefits available from surgery. Indications for having surgery sooner than later include:
• Severe tricuspid valve regurgitation in the presence of mitral valve disease, pulmonary hypertension, or right ventricular failure.
• Severe tricuspid valve regurgitation as diagnosed by echocardiography.

Traditional vs. Minimally Invasive Surgical Approaches
Patients who need surgery on the tricuspid valve alone or who need multi-valve surgery may be candidates for the minimally invasive approach, but the surgeon makes the determination based on each individual case. The patient’s individual anatomy, diagnosis, and overall heart function are contributing factors. This approach may also include the use of a surgical robot.

Traditional Minimally Invasive
Incision length 6- to 8-inches 2- to 4-inches
Incision location Sternum Sternum or between ribs
Length of hospital stay (avg) 5 days 3.5 days
Trauma Higher Lower
Blood loss Higher Lower

Advantages of Tricuspid Valve Repair
Tricuspid valve repair is the best option for patients with tricuspid valve regurgitation and for many with tricuspid valve stenosis because of the following advantages:
• Better survival and outcome statistics
• Better preservation of heart function and anatomy
• Lower risk of complications, such as stroke or endocarditis (infection)
• No need for anticoagulation therapy
• Improved lifestyle

Tricuspid valve repair is technically more difficult than tricuspid valve replacement. Operative success depends on the valve condition, the experience, training, and skill level of the surgeon, and the collaboration between the echocardiographer and the surgeon.

Surgical Techniques for Tricuspid Valve Repair
• Problems with the posterior leaflet are generally corrected with a small triangular or quadrangular resection of the abnormal portion of the valve.
• Problems with the anterior leaflet are managed by transferring or creating new chordae tendinae.
• Tricuspid valve stenosis can be repaired with a tricuspid commisurotomy.
• All repairs include an annuloplasty, which is a complete or partial ring placed around the opening of the valve to restore and retain its correct size and shape.
• Tricuspid valve repair techniques are technically challenging and require a skilled and experienced surgical team to achieve the best result.

Complicated Repair Situations
Patients with tricuspid valve disease often have complicating conditions, including:
• A tricuspid valve that has been damaged by endocarditis.
• A tricuspid valve that has been damaged by calcium deposits.
• A previous tricuspid valve repair that has failed.
• Atrial fibrillation, an abnormal heart rhythm that may require a concurrent ablation or Maze procedure.
Coronary artery bypass surgery, aortic valve surgery, mitral valve surgery, or other heart surgery that has caused a new problem with the tricuspid valve.

Results of Tricuspid Valve Repair
cardiovascular surgeon can predict but cannot guarantee the likelihood of a successful tricuspid valve repair. The long-term outcome of a successful repair is most likely to be good, especially for degenerative valve disease. Statistics show up to a 95% chance that a repaired valve will need no further intervention in the next 10 to 20 years (fewer for a more complex repair). However, rheumatic fever can continue to damage a repaired valve, and tricuspid regurgitation associated with coronary artery disease creates unpredictable repair results.

Tricuspid Valve Replacement
If valve repair is not an option, the valve may need to be replaced. Tricuspid valve replacement is an open heart procedure performed by a cardiothoracic surgeon to treat tricuspid valve stenosis and tricuspid valve regurgitation (or a combination of the two called myxomatous valve disease). The native (original) valve is removed, and a new valve is sewn in its place. The new valve can be a biological, homograft, or mechanical valve.

Biological Valves
Biological valves are made from pig tissue (porcine), cow tissue (bovine), or pericardium from other species. The natural tissue is supported by an artificial framework, which gives it structure and allows it to be surgically implanted. Biological tissue valves are also called bioprosthetic valves. They last from 15 to 20 years after implantation, are readily accepted by the body, and usually do not cause blood clotting problems.

Homograft Valves
A homograft valve has been donated from another human who has died. After removal from a donated human heart, it is treated with antibiotics, placed in preservative, and frozen under sterile conditions. Homograft valves are sometimes used in the tricuspid position, especially in severe cases of endocarditis.

Mechanical Valves
Mechanical valves are usually bileaflet valves that are made with non-reactive, well tolerated materials like pyrolite (qualities similar to a diamond) carbon leaflets surrounded with a polyester knit fabric—covered ring. Surgeons choose the type of valve to implant based on how it is sewn into place, but few differences exist between them. The advantage of mechanical valves is their excellent durability—they do not wear out over time. A huge disadvantage is that blood clots on mechanical valves. Because of this risk, patients with a mechanical heart valve must take anticoagulant medications or “blood thinners” and be routinely tested for its level in their blood for the rest of their lives. Blood clots also pose a serious risk for causing stroke.

Past history of heart surgery, patient age, general health, and other conditions that require surgical treatment affect individual risk. Each patient who undergoes elective heart valve surgery should discuss risk factors and potential outcomes with his or her surgeon prior to undergoing the operation.

Life after Tricuspid Valve Surgery
Patients who undergo successful tricuspid valve surgery can expect to return to their preoperative condition or better. After wounds have healed, few if any restrictions are placed on the patient’s activity.
