Heart Valve Disease Evaluation & Treatment
Dr. Praneeth Polamuri, Senior Consultant Interventional Cardiologist, Yashoda Hospital, Secunderabad
What Is Heart Valve Disease?
The heart contains four valves that act like one-way doors, ensuring blood flows in the correct direction.
When a valve becomes narrowed (**stenosis**) or leaky (**regurgitation**), the heart must work harder to pump blood effectively.
Heart valve disease can develop gradually over many years and may remain unnoticed until symptoms appear.
Fortunately, modern treatments—including minimally invasive procedures such as "TAVR (Transcatheter Aortic Valve Replacement)"—have transformed outcomes for many patients.
How Do Heart Valves Work?
Think of the heart valves as traffic signals controlling blood flow.
Healthy valves open fully to allow smooth blood flow and close tightly to prevent backward leakage.
Problems occur when:
-
Valve Narrowing (Stenosis) - The valve becomes stiff and does not open properly, restricting blood flow.
-
Valve Leakage (Regurgitation) - The valve does not close properly, allowing blood to flow backward.
Both conditions increase the workload on the heart.
Common Types of Valve Disease
Aortic Stenosis
A narrowing of the aortic valve that restricts blood flow from the heart to the body.
Common in older adults.
Aortic Regurgitation
The aortic valve leaks, causing blood to flow backward into the heart.
Mitral Regurgitation
One of the most common valve disorders where the mitral valve leaks.
Mitral Stenosis
Usually caused by rheumatic heart disease.
Tricuspid Valve Disease
May develop secondary to heart failure or pulmonary hypertension.
Congenital Valve Abnormalities
Some people are born with abnormal valves such as bicuspid aortic valve.
Common Symptoms of Heart Valve Disease
-
Fatigue
-
Reduced exercise capacity
-
Dizziness
-
Fainting spells
-
Swelling of the feet
-
Irregular heartbeat
Symptoms often develop gradually.
When Should You See a Cardiologist?
Seek evaluation if you experience:
-
Unexplained breathlessness
-
Reduced stamina
-
New heart murmur
-
Chest discomfort during exertion
-
Dizziness or fainting
-
Swelling of the feet
Why Early Diagnosis Matters
Many patients ignore symptoms because they develop slowly.
However, untreated valve disease may eventually lead to:
-
Pulmonary hypertension
-
Recurrent hospitalizations
-
Reduced life expectancy
Timely treatment often prevents these complications.
How Is Valve Disease Diagnosed?
Clinical Examination - A heart murmur may provide the first clue.
Echocardiogram - The most important test for evaluating valve disease.
It assesses:
-
Valve narrowing
-
Valve leakage
-
Heart pumping function
-
Chamber enlargement
ECG - May identify rhythm abnormalities or evidence of heart enlargement
Chest X-Ray - Can reveal heart enlargement or lung congestion.
CT Scan - Often used for planning TAVR and other structural heart procedures.
Cardiac Catheterization - Sometimes performed before valve intervention to evaluate coronary arteries.
Treatment Options
Treatment depends on:
-
Severity
-
Symptoms
-
Age
-
Overall health
-
Type of valve involved
Medical Therapy
Medications may help control symptoms but usually do not correct significant valve abnormalities.
Surgical Valve Replacement
Open-heart surgery remains an excellent option for many patients.
TAVR (Transcatheter Aortic Valve Replacement)
A minimally invasive alternative for treating severe aortic stenosis without open-heart surgery.
Mitral Valve Repair
Many leaking mitral valves can be repaired rather than replaced.
Transcatheter Mitral and Tricuspid Procedures
Advanced catheter-based therapies are increasingly available for selected patients.
Living With Valve Disease
Many patients continue active, fulfilling lives with proper monitoring and treatment.
Regular follow-up is essential to determine the optimal timing of intervention.
A Reassuring Thought
A diagnosis of valve disease does not automatically mean surgery is needed immediately. Many patients are monitored safely for years, while others benefit greatly from timely intervention before symptoms become severe.
Frequently Asked Questions (FAQ)
1. What is heart valve disease?
Heart valve disease occurs when one or more heart valves become narrowed or leaky, affecting normal blood flow through the heart.
2. What are the symptoms of heart valve disease?
Common symptoms include breathlessness, fatigue, chest discomfort, dizziness, fainting, swelling of the feet, and palpitations.
3. Can heart valve disease cause shortness of breath?
Yes. Breathlessness is one of the most common symptoms of significant valve disease.
4. What causes heart valve disease?
Common causes include aging, rheumatic fever, congenital abnormalities, infections, and degenerative valve changes.
5. What is aortic stenosis?
Aortic stenosis is a narrowing of the aortic valve that restricts blood flow from the heart to the rest of the body.
6. What is mitral valve regurgitation?
Mitral regurgitation occurs when the mitral valve leaks, allowing blood to flow backward into the heart.
7. Can valve disease be treated without surgery?
Mild valve disease may only require monitoring. Significant valve disease often requires repair or replacement.
8. What is TAVR?
TAVR (Transcatheter Aortic Valve Replacement) is a minimally invasive procedure used to replace a diseased aortic valve without open-heart surgery.
9. Who is a candidate for TAVR?
Many patients with severe aortic stenosis, including elderly individuals and selected younger patients, may be candidates after evaluation.
10. Is TAVR safer than open-heart surgery?
Both treatments are effective. The best option depends on age, anatomy, overall health, and individual patient characteristics.
11. How long does a TAVR procedure take?
Most TAVR procedures take approximately 1–2 hours.
12. What is the recovery time after TAVR?
Most patients recover much faster than with traditional surgery and may return home within a few days.
13. Can heart valve disease cause dizziness or fainting?
Yes. Severe aortic stenosis commonly causes dizziness or fainting during exertion.
14. What is a heart murmur?
A heart murmur is an abnormal sound heard during examination that may indicate valve disease.
15. How often should valve disease be monitored?
The frequency depends on severity. Mild disease may require annual follow-up, while severe disease may need closer monitoring.
16. Can valve disease lead to heart failure?
Yes. Untreated severe valve disease can eventually weaken the heart and cause heart failure.
17. Can exercise worsen valve disease?
Most patients can remain active, but exercise recommendations depend on the severity and type of valve abnormality.
18. Is valve disease hereditary?
Some valve disorders, such as bicuspid aortic valve, may run in families.
19. What happens if severe valve disease is left untreated?
Untreated severe valve disease can lead to heart failure, arrhythmias, stroke, hospitalization, and reduced survival.
20. When should valve replacement be considered?
Valve replacement is typically recommended when valve disease becomes severe, symptoms develop, or heart function begins to decline.
