Mitral & Tricuspid Valve Interventions
Dr. Praneeth Polamuri, Senior Consultant Interventional Cardiologist, Yashoda Hospital, Secunderabad*

What Are Mitral and Tricuspid Valve Diseases? 

The mitral and tricuspid valves are two important valves that regulate blood flow through the heart. Think of these valves as one-way doors. When they open and close normally, blood flows efficiently.

 

When they become leaky or narrowed, the heart must work harder, which can eventually lead to breathlessness, fatigue, swelling, and heart failure.

 

Advances in structural heart interventions now allow many patients to be treated using minimally invasive catheter-based procedures rather than open-heart surgery.

 

What Does the Mitral Valve Do? 

The mitral valve lies between the left upper chamber (left atrium) and left lower chamber (left ventricle). It ensures blood flows forward and prevents backward leakage.

Problems include:

Mitral Regurgitation (Leaky Mitral Valve) - Blood leaks backward into the left atrium.

Mitral Stenosis (Narrowed Mitral Valve) - The valve becomes narrowed and restricts blood flow.

 

What Does the Tricuspid Valve Do?

The tricuspid valve lies between the right atrium and right ventricle.

Its role is to prevent backward blood flow on the right side of the heart.

Tricuspid Regurgitation - The most common tricuspid valve disorder. 

Blood leaks backward, often causing:

• Leg swelling

• Abdominal swelling

• Fatigue

• Breathlessness

​

Common Symptoms of Mitral and Tricuspid Valve Disease

• Shortness of breath

• Fatigue

• Reduced exercise capacity

• Swelling of feet

• Abdominal swelling

• Palpitations

• Dizziness

• Heart failure symptoms

• Irregular heartbeat (Atrial Fibrillation)

Symptoms often develop gradually.

​

Why Is Early Diagnosis Important?

Many patients assume symptoms are due to aging.

However, untreated valve disease may eventually lead to:

• Heart failure

• Pulmonary hypertension

• Atrial fibrillation

• Recurrent hospitalization

• Reduced quality of life

Timely intervention can preserve heart function and improve long-term outcomes.

 

How Are Mitral and Tricuspid Valve Diseases Diagnosed?

1. Echocardiography - The most important test. It evaluates:

• Severity of leakage

• Valve structure

• Heart function

• Pulmonary pressures

2. Transesophageal Echocardiography (TEE) - Provides detailed images of the valve. Often used before intervention.

3. Cardiac CT Scan -Useful for procedural planning.

4. Cardiac Catheterization - May be performed to assess coronary arteries before intervention.

 

Treatment Options 

Treatment depends on:

• Severity of valve disease

• Symptoms

• Heart function

• Surgical risk

• Overall health

​

Medical Therapy

Medications help control symptoms but do not correct severe valve leakage.

Common medications include:

• Diuretics

• Blood pressure medications

• Heart failure therapies

​

Surgical Valve Repair or Replacement

Open-heart surgery remains an excellent option for many patients.

 

What Are Transcatheter Mitral and Tricuspid Interventions?

Modern catheter-based procedures allow treatment without open-heart surgery in selected patients. These procedures are collectively called: Structural Heart Interventions

 

MitraClip (Transcatheter Edge-to-Edge Repair(TEER))

MitraClip is a minimally invasive procedure used to treat selected patients with severe mitral regurgitation. A small clip is placed on the mitral valve leaflets to reduce leakage. 

Benefits:

• No chest opening

• Faster recovery

• Improved symptoms

• Reduced hospitalization

​

Transcatheter Mitral Valve Replacement (TMVR)

TMVR is an emerging therapy that replaces the mitral valve using catheter-based technology.

Suitable for selected high-risk patients.

 

Tricuspid Valve Repair

Transcatheter edge-to-edge repair can now be performed for selected patients with severe tricuspid regurgitation. This helps reduce: Swelling, Breathlessness and Heart failure symptoms.

​​

TricValve & Caval Valve Implantation

Advanced therapies such as TricValve may be considered in selected patients with severe tricuspid regurgitation who are not surgical candidates.

 

Who May Benefit From Transcatheter Valve Interventions?

Patients with:

• Severe mitral regurgitation

• Severe tricuspid regurgitation

• High surgical risk

• Recurrent heart failure

• Previous cardiac surgery

• Multiple medical conditions

may be candidates for catheter-based treatment.

 

Benefits of Transcatheter Valve Procedures

These procedures may:

• Improve breathlessness

• Improve exercise capacity

• Reduce swelling

• Improve quality of life

• Reduce heart failure admissions

• Avoid open-heart surgery in selected patients

 

Recovery After Mitral or Tricuspid Intervention

Most patients:

• Walk within hours

• Have shorter hospital stays

• Recover faster than after surgery

• Return to normal activities sooner

Recovery varies based on individual circumstances.

A Reassuring Thought

A diagnosis of mitral or tricuspid valve disease does not automatically mean open-heart surgery is required. Modern structural heart interventions have expanded treatment options and allow many patients to benefit from minimally invasive therapies with excellent outcomes.
