What is Tricuspid Valve?
The tricuspid valve is a valve located between the right atrium and the right ventricle of the heart. This valve consists of three leaflets and regulates the passage of blood from the right atrium to the right ventricle. The tricuspid valve facilitates the pumping of blood to the pulmonary circulation.
The tricuspid valve regulates the flow of deoxygenated blood on the right side of the heart. Venous (deoxygenated) blood coming from the right atrium passes through the tricuspid valve to reach the right ventricle and is then pumped to the lungs through the pulmonary artery. In the lungs, the blood is oxygenated and returns to the left side of the heart, passing through the mitral valve this time, and is pumped to the body through the aorta. This way, the heart ensures the circulation of blood carrying oxygen and nutrients to different parts of the body.
What Are Tricuspid Valve Diseases?
Tricuspid valve diseases typically refer to conditions that arise due to malfunctions or structural problems in the valve. Tricuspid valve diseases can include the following:
Tricuspid Valve Insufficiency (Regurgitation): Tricuspid valve insufficiency occurs when the valve does not close or does not close tightly enough, causing blood to flow back from the right atrium to the right ventricle. This condition can increase the workload of the heart due to the backward flow of blood in the right atrium.
Tricuspid Valve Stenosis: Tricuspid valve stenosis occurs when the valve becomes stiff and narrows, restricting the flow of blood from the right atrium to the right ventricle. This condition can lead to difficulty in the passage of blood from the right atrium and increased workload on the right ventricle.
Tricuspid Valve Endocarditis: Tricuspid valve endocarditis is the inflammation of the tricuspid valve caused by an infection. This condition typically results from a bacterial infection. Endocarditis is a serious condition affecting heart valves and requires treatment.
What Are the Symptoms of Tricuspid Valve Diseases?
Tricuspid valve diseases are often associated with other heart valve diseases. Symptoms may include shortness of breath, edema (fluid accumulation in the body), fatigue, palpitations, and enlarged liver.
Treatment Methods for Tricuspid Valve Diseases:
Diagnosis and treatment usually require a detailed evaluation by cardiologists. The treatment of tricuspid valve diseases can vary depending on the type of disease, its severity, symptoms, and the overall health of the patient.
Medical Treatment:
- Diuretics: Used to eliminate excess fluid in the body.
- ACE inhibitors or angiotensin receptor blockers: May help regulate blood pressure.
- Beta-blockers: Can help control heart rate and contraction.
Heart Valve Surgery:
- Tricuspid valve repair: If possible, the valve can be repaired to restore functionality.
- Tricuspid valve replacement: If the valve is severely damaged or cannot be repaired, it can be replaced with an artificial valve.
Balloon Valvuloplasty:
In cases of stenosis, balloon valvuloplasty can be performed by reaching the heart valves through a catheter. In this procedure, the balloon is inflated to open the valve and improve blood flow.
Endovascular Interventions:
In some cases, tricuspid valve problems can be treated using minimally invasive procedures. Catheter-based procedures may be considered as non-surgical options.
Anticoagulant Treatment:
To reduce the risk of endocarditis, doctors may prescribe anticoagulant medications. These medications prevent the formation of clots on the valves.
Disease Management:
Lifestyle changes and exercise programs may be recommended to alleviate symptoms and control the progression of the disease.
When Should Surgery Be Considered for Tricuspid Valve Diseases?
Situations in which surgery for tricuspid valve diseases may be considered include:
Severe Tricuspid Valve Insufficiency or Stenosis:
If tricuspid valve insufficiency or stenosis is severe and causing symptoms, surgery may be considered. Symptoms may include shortness of breath, edema, fatigue, palpitations, among others.
Presence of Endocarditis in the Patient:
If there is an infection (endocarditis) on the tricuspid valve, surgery may be considered to control the disease and preserve the heart valves.
Coexistence with Left Heart Valve Diseases:
Tricuspid valve diseases are often seen in conjunction with left heart valve diseases. In patients with tricuspid valve disease along with problems in the left heart valves, if surgery is performed on the left heart valves, the tricuspid valve may also be evaluated simultaneously.
Significant Functional Impairment:
Functional tricuspid valve insufficiency typically occurs as a result of left heart diseases or ventricular dysfunction. In such cases, when surgeries are performed to correct left heart problems, the tricuspid valve may also be evaluated.
Presence of Symptoms:
The presence of symptoms related to tricuspid valve diseases plays a significant role in the decision to undergo surgery. In patients with severe symptoms, surgery may be considered.
Overall Health of the Patient:
The overall health of the patient influences the feasibility of surgery. The decision is made by considering the risks and benefits of surgery.
