The heart has four valves that keep blood moving in the correct direction. A valve may become narrowed, called stenosis, or fail to close completely, called regurgitation.
Mild valve disease may need only periodic follow-up. More advanced disease can raise pressure inside the heart, enlarge a chamber, weaken the heart muscle, or cause symptoms that gradually limit daily life.
The timing of treatment matters. Acting too early can expose a patient to unnecessary risk, while waiting after the heart begins to suffer can reduce the chance of full recovery.
What symptoms can valve disease cause?
Symptoms do not always track perfectly with the reported severity. A person may unconsciously slow down and believe nothing has changed. Comparing current activity with the prior year can be more revealing.
- Shortness of breath with activity or while lying down
- Fatigue or reduced exercise tolerance
- Chest pressure
- Dizziness or fainting
- Palpitations
- Leg or abdominal swelling
- Rapid weight gain from fluid
Which valves are commonly affected?
Aortic stenosis becomes more common with age as the valve calcifies. The mitral valve may leak because of prolapse, heart-muscle damage, or enlargement of the heart. Tricuspid leakage often reflects pressure or enlargement on the right side of the heart.
Infection, congenital anatomy, rheumatic disease, prior radiation, and certain medications can also affect valves. The cause influences both surveillance and treatment.
When are valve symptoms urgent?
Call 911 for severe breathing difficulty, fainting with chest pressure, symptoms of a heart attack or stroke, or a sudden major decline.
Fever with a new murmur, unexplained chills, or signs of infection deserves prompt evaluation because infection of a heart valve can become serious quickly.
How is valve disease diagnosed?
An echocardiogram is the central test. It shows valve movement, blood-flow direction and speed, chamber size, pumping function, and pressure estimates.
A transesophageal echocardiogram, cardiac CT, stress testing, or catheterization may be needed when standard images are limited or a procedure is being planned. Comparing serial echocardiograms is often more useful than focusing on one isolated number.
How is heart valve disease treated?
Medication can relieve congestion, control blood pressure, or manage an associated rhythm problem, but it does not mechanically open a severely narrowed valve.
Some patients need surgical repair or replacement. Others may be candidates for a transcatheter valve procedure. The decision considers symptoms, heart response, anatomy, age, other illnesses, and the durability of each option.
Dr. Patel can monitor valve disease, interpret imaging, optimize associated heart conditions, and coordinate evaluation with an appropriate multidisciplinary valve team when intervention should be considered.
Frequently asked questions
Does a heart murmur always mean serious valve disease?
No. Some murmurs are harmless, while others reflect valve disease. An examination and echocardiogram clarify the cause.
How often should an echocardiogram be repeated?
The interval depends on the valve, severity, symptoms, and change over time. New symptoms may justify earlier imaging.
Can a valve be treated without open-heart surgery?
Sometimes. Transcatheter options exist for selected valve problems, but anatomy and overall health determine candidacy.
