Degenerative valve disease is a common, age-related set of problems in which one or more heart valves gradually lose their normal shape and flexibility. Over years, a valve may become stiff and narrow, leak, or do a bit of both. Many people feel well for a long time because the heart can compensate quietly—until it can’t, and symptoms begin to show up during everyday activities like climbing stairs or carrying groceries.

What makes this condition challenging is its slow pace and its variety: the aortic valve often stiffens (aortic stenosis), while the mitral valve may become “floppy” and leak (mitral regurgitation). The good news is that modern imaging can detect changes early, and today’s treatments range from careful monitoring to catheter-based repairs and durable valve replacements.

What it is and why it matters

Your heart has four valves—think of them as one-way doors that keep blood moving forward. Degenerative valve disease means those doors slowly wear down due to aging-related changes in the valve tissue. Over time, valve leaflets can thicken, calcify (build up calcium deposits), stretch, or lose their precise alignment. The result is usually one of two mechanical problems:

  • Stenosis: the valve becomes stiff and narrowed, so blood has trouble getting through.
  • Regurgitation: the valve does not seal tightly, so blood leaks backward.

These problems stress the heart in different ways. Stenosis forces the heart to pump harder against resistance, which can lead to thickened heart muscle and eventually weakness or heart failure. Regurgitation makes the heart handle extra volume, which can enlarge chambers, trigger rhythm problems like atrial fibrillation, and raise pressure in the lungs.

Degenerative valve disease most often involves:

  • Aortic valve: commonly becomes calcified and narrowed with age (degenerative aortic stenosis).
  • Mitral valve: can become redundant or “billowy,” often due to myxomatous degeneration (a softening and stretching of valve tissue), leading to mitral valve prolapse and leakage.
  • Tricuspid valve: may leak later in life, sometimes as a downstream effect of left-sided valve disease or long-standing lung pressure changes.

A key feature is that severity and symptoms do not always match perfectly. Some people with significant valve disease feel surprisingly normal, while others feel limited with “moderate” findings because of lung disease, anemia, deconditioning, or other heart problems. That is why the condition is managed as a long-term relationship with careful measurement, not a single yes/no diagnosis.

The reason it matters is simple: once the heart begins to struggle—especially with severe aortic stenosis or significant mitral regurgitation—timely valve intervention can prevent irreversible damage and can dramatically improve both longevity and quality of life.

What causes it and who is at risk

Degenerative valve disease is not caused by one single trigger. It is a gradual remodeling process influenced by biology, mechanics, and lifetime exposures. Every heartbeat bends and flexes valve leaflets. With age, the tissue’s repair systems become less efficient, and small injuries accumulate.

Common underlying processes include:

  • Calcification and fibrosis: the valve becomes thicker and stiffer. This is especially typical for the aortic valve.
  • Tissue stretching and redundancy: parts of the mitral valve (leaflets or supporting chords) can elongate, leading to prolapse and leakage.
  • Annular calcification: calcium can build up around the mitral valve ring (the annulus), limiting motion and causing leakage, narrowing, or both.

Risk tends to rise with:

  • Age: the strongest driver—rates climb sharply after midlife.
  • High blood pressure: increases mechanical stress on valves and the heart.
  • High LDL cholesterol and other lipid disorders: associated with faster aortic valve calcification in many studies, even though cholesterol-lowering alone has not reliably stopped progression once stenosis is established.
  • Diabetes and smoking: linked to vascular and inflammatory changes that can parallel valve degeneration.
  • Chronic kidney disease: disturbances in calcium-phosphate balance can accelerate calcification, sometimes at younger ages.
  • Prior chest radiation: can affect valves years later, especially the aortic and mitral valves.
  • Congenital valve anatomy: for example, a bicuspid aortic valve (two leaflets instead of three) experiences abnormal flow and often degenerates earlier.
  • Family history and connective tissue traits: some families carry a tendency toward mitral valve prolapse or early calcification.

It also helps to separate degenerative valve disease from other major categories:

  • Rheumatic valve disease (linked to rheumatic fever) often scars valves in a different pattern.
  • Infective endocarditis is an infection of the valve and can cause sudden, severe leakage.
  • Functional regurgitation happens when the heart chamber enlarges and pulls a normal valve apart; degenerative disease, in contrast, begins in the valve structure itself.

If you are at higher risk, the most protective steps are not exotic: keep blood pressure controlled, avoid tobacco, manage diabetes, maintain regular activity, and get evaluated promptly if new breathlessness, chest pressure, or fainting appears.

First symptoms and serious complications

Many people have no symptoms early on. Degenerative valve disease often appears first as a murmur found on a routine exam or as an “incidental” finding on an ultrasound done for another reason. When symptoms start, they may be subtle and easy to blame on aging or stress.

Common early symptoms across valve types include:

  • Shortness of breath with exertion
  • Reduced exercise tolerance (“I can’t do what I used to”)
  • Fatigue that feels out of proportion
  • Heart pounding, fluttering, or irregular beats
  • Swelling in ankles or feet, especially later in the day

Some symptom patterns hint at specific valve problems:

  • Aortic stenosis: chest pressure with activity, dizziness or fainting, and breathlessness are classic warning signs. People may notice they slow down their pace without realizing it.
  • Mitral regurgitation: breathlessness can come from congestion in the lungs; palpitations may signal atrial fibrillation. Some people notice waking up short of breath or needing extra pillows.
  • Tricuspid regurgitation: swelling, abdominal fullness, and weight gain from fluid retention can be prominent.

Potential complications are the main reason clinicians take progression seriously:

  • Heart failure: either from pressure overload (stenosis) or volume overload (regurgitation).
  • Atrial fibrillation: especially with mitral disease; it can worsen breathlessness and raises stroke risk.
  • Pulmonary hypertension: elevated lung pressures due to long-standing left-sided valve disease.
  • Stroke and systemic embolism: typically from atrial fibrillation or clots forming in enlarged chambers.
  • Sudden deterioration: severe aortic stenosis can become dangerous quickly once symptoms begin.
  • Infective endocarditis: degenerative valves can be a vulnerable surface for infection, though routine antibiotics before dental work are only recommended for specific high-risk groups.

A practical “listen to your body” rule is this: if you find yourself avoiding stairs, stopping more often during walks, or needing longer recovery time after ordinary tasks, it is worth reporting—especially if you already know you have valve disease. These small changes often carry more meaning than any single number on a report.

How doctors diagnose and stage it

Diagnosis starts with a careful history and physical exam. Clinicians look for changes in stamina, breathlessness patterns, fainting episodes, chest discomfort, swelling, and palpitations. On exam, the timing and quality of a murmur, extra heart sounds, or signs of fluid overload can suggest which valve is involved and how advanced the disease may be.

The cornerstone test is transthoracic echocardiography (TTE)—a standard heart ultrasound. It shows valve anatomy, measures how tight or leaky a valve is, and evaluates how the heart muscle is coping. Doppler imaging measures blood flow speeds and pressure gradients, which helps define severity.

Additional testing may be used to answer specific questions:

  • Transesophageal echocardiography (TEE): a closer look from the esophagus, often used for detailed mitral valve assessment or planning a procedure.
  • Stress testing (exercise or medication-based): helpful when symptoms and ultrasound findings do not line up, or to unmask limited reserve in “asymptomatic” severe disease.
  • CT scanning: can measure aortic valve calcium burden, clarify anatomy, and assist with transcatheter valve planning.
  • Cardiac MRI: useful for precise chamber volumes, function, and scar assessment in selected cases.
  • Cardiac catheterization: sometimes needed when noninvasive tests conflict, or to evaluate coronary artery disease before surgery.

Staging is not only about the valve. Clinicians also track the heart’s response—chamber size, pumping function, lung pressures, and rhythm. Two people can have similar valve measurements but very different risk depending on these downstream effects.

Follow-up intervals depend on severity and stability. Mild disease may need periodic reassessment over years, while moderate to severe disease is watched more closely, often with repeat imaging every 6–12 months in higher-risk situations. The goal is to time intervention so it happens before lasting damage occurs, not after the heart has already remodeled past the point of easy recovery.

If you read your own report, focus on trends and the “bottom line” impression. A single number rarely tells the whole story; changes over time and how you feel day-to-day are often the most actionable information.

Treatment options and what to expect

Treatment depends on which valve is affected, how severe the problem is, how the heart is responding, and your overall health. A central truth is that medications do not “fix” a mechanical valve problem—they help manage symptoms and protect the heart while the team monitors progression or prepares for an intervention.

Common medical strategies include:

  • Diuretics (“water pills”): reduce congestion and swelling when fluid builds up.
  • Blood pressure control: lowers stress on the heart and can lessen regurgitation in some settings.
  • Rate or rhythm control for atrial fibrillation: improves symptoms and heart efficiency.
  • Anticoagulation (blood thinners): used when atrial fibrillation or certain valve replacements raise clot risk.

When valve disease becomes severe or begins harming the heart, procedures are considered. Options include:

Surgical repair or replacement

  • Repair is often preferred for degenerative mitral regurgitation when feasible, because it preserves native tissue and can offer excellent long-term results.
  • Replacement may be needed when repair is unlikely to be durable or anatomy is complex.
  • Valve choice matters: mechanical valves last longer but require lifelong anticoagulation; bioprosthetic (tissue) valves usually avoid long-term anticoagulation but may wear out over time.

Transcatheter (catheter-based) therapies

  • TAVR (transcatheter aortic valve replacement): replaces the aortic valve through blood vessels, often with faster recovery than open surgery in appropriate patients.
  • TEER (transcatheter edge-to-edge repair): a minimally invasive approach for selected patients with mitral regurgitation who are high surgical risk or have suitable anatomy.

What to expect in decision-making:

  • The best centers use a multidisciplinary heart team approach, combining imaging specialists, interventional cardiologists, surgeons, and anesthesiology to match the procedure to the person—not the other way around.
  • Timing is critical. Waiting until the heart is clearly failing can reduce the chance of full recovery. On the other hand, intervening too early can expose you to procedural risks before benefits are clear. Good follow-up aims for the “right window.”

Recovery varies. Many people feel a noticeable improvement in breathing and stamina within weeks after successful intervention, but rebuilding strength often takes structured activity, sometimes with cardiac rehabilitation.

Living with it and when to seek care

Living well with degenerative valve disease is largely about staying engaged with your baseline and noticing meaningful change early. Most people do best with a simple plan that covers symptoms, lifestyle, and follow-up.

Daily and weekly habits that help:

  • Track a few signals: breathlessness with usual activity, swelling, weight changes, palpitations, and dizziness. A sudden 1–2 kg weight jump over a few days can signal fluid retention.
  • Stay active within safe limits: regular walking, cycling, or light strength work improves conditioning and reduces deconditioning-related breathlessness. Ask your clinician about intensity limits if you have severe stenosis or are symptomatic.
  • Heart-smart eating: prioritize vegetables, fruits, legumes, fish, and unsalted nuts; keep sodium modest if you retain fluid. If you use diuretics, ask whether you need potassium monitoring.
  • Protect sleep and breathing: untreated sleep apnea can worsen blood pressure and strain the heart.
  • Vaccinations and infection prevention: respiratory infections can trigger decompensation. Staying current can reduce risk.
  • Dental hygiene: gum disease and dental infections are avoidable sources of bloodstream bacteria. Brush, floss, and keep regular dental care. Antibiotics before dental work are reserved for certain high-risk conditions—your cardiology team can clarify if you qualify.

Follow-up is part of treatment, not an afterthought. Bring a short list of questions to appointments:

  • Has my valve severity changed compared with last time?
  • How is my heart responding (size, function, lung pressure)?
  • What symptom changes should trigger a call?
  • What activity level is safest for me right now?
  • If a procedure is likely in the future, what signs suggest it is time?

Seek urgent care (or emergency evaluation) if you have:

  • Fainting, near-fainting, or severe dizziness—especially with exertion
  • New chest pressure or pain
  • Sudden shortness of breath at rest, coughing up frothy sputum, or severe wheezing
  • New one-sided weakness, facial droop, trouble speaking, or sudden vision loss
  • Rapid, sustained palpitations with lightheadedness or breathlessness

Finally, remember that “degenerative” does not mean “hopeless.” It means gradual—often giving you time to plan, choose the right center, and intervene at the moment the benefit is highest.
