Valvular Heart Disease: Symptoms, Types, and Treatment

Your heart has four valves, and they all have the same job: keep blood moving in the right direction.
Think of them like the world’s most important one-way doors. When a valve gets stiff, leaky, or
floppy, your heart has to work overtimelike a delivery driver stuck with a car door that won’t
shut. That’s valvular heart disease (also called heart valve disease):
a group of conditions that affect how your valves open and close, and therefore how efficiently
your heart pumps blood.

The good news: valve disease is often manageable, and modern treatment has come a long wayfrom
medications that ease symptoms to minimally invasive procedures that can repair or replace a valve
through a catheter. The key is recognizing symptoms early, getting the right tests, and matching
the treatment to the type and severity of the valve problem.

What Is Valvular Heart Disease?

Valvular heart disease happens when one or more heart valves don’t function properly. Your heart
has four valves: aortic, mitral, tricuspid, and
pulmonary. Each valve opens and closes with every heartbeat to keep blood flowing
forwardnever backward.

The Three Main “Ways a Valve Misbehaves”

• Stenosis: The valve doesn’t open fully, so blood has to squeeze through a smaller
  opening. (Traffic jam at a toll booth.)
• Regurgitation (leakage): The valve doesn’t close tightly, so blood leaks backward.
  (Like trying to drink through a straw with a crack in it.)
• Prolapse: Valve flaps bulge backward and may not seal properly. (A door that bows
  instead of latching.)

Some people have valve disease for years with no obvious symptoms. Others notice changes gradually:
less stamina, more shortness of breath, or swelling. Either way, valve disease isn’t something to
“walk off.” It’s something to evaluatebecause the heart is very polite and will compensate… until
it can’t.

Symptoms of Valvular Heart Disease

Symptoms depend on which valve is affected and whether the problem is narrowing, leaking, or both.
Many symptoms overlap with other conditions, which is why valve disease can be sneaky.

Common Symptoms

• Shortness of breath (with activity, at rest, or when lying down)
• Fatigue or reduced exercise tolerance (“I used to do stairs fine… now I negotiate with them.”)
• Chest discomfort or pressure
• Dizziness or fainting
• Heart palpitations or irregular heartbeat
• Swelling in ankles, feet, legs, or abdomen
• Rapid weight gain from fluid retention

Red-Flag Symptoms: When to Seek Urgent Care

Get emergency help if you have chest pain that doesn’t go away, fainting, severe shortness of breath,
sudden weakness or trouble speaking, or symptoms of a possible stroke. Severe valve disease can lead
to heart failure, dangerous rhythms, or reduced blood flow to vital organs.

Types of Valvular Heart Disease (By Valve)

Valve disease is often described by which valve is affected and how it’s affected.
Here are the major types you’ll see most often.

Aortic Valve Disease

The aortic valve is the final “exit door” that lets oxygen-rich blood leave the left ventricle and
flow into the aorta (the body’s main artery).

Aortic Stenosis

Aortic stenosis means the aortic valve becomes narrowedoften due to age-related
calcification or a congenital valve shape such as a bicuspid aortic valve. Mild stenosis may not
cause symptoms. Severe stenosis can cause chest pain, fainting, and breathlessnessespecially on
exertionbecause the heart struggles to push blood through a tight opening.

Aortic Regurgitation

Aortic regurgitation means the valve leaks, allowing blood to flow backward into the
left ventricle between beats. Over time, the ventricle may enlarge from handling extra volume. Some
people feel palpitations, shortness of breath, or fatigue; others have no symptoms until the leak
becomes significant.

Mitral Valve Disease

The mitral valve sits between the left atrium and left ventricle. It’s a busy gatewayso when it
leaks or narrows, it can affect the lungs and exercise capacity quickly.

Mitral Regurgitation

Mitral regurgitation happens when the valve doesn’t seal tightly and blood leaks
backward into the left atrium. Causes include mitral valve prolapse, degenerative changes, damage
after a heart attack, or enlargement of the heart that pulls the valve apart. People may develop
shortness of breath, fatigue, or irregular heart rhythms like atrial fibrillation.

Mitral Stenosis

Mitral stenosis is narrowing of the mitral valve, historically linked to rheumatic
fever. It can raise pressure in the left atrium and lungs, causing shortness of breathespecially
with activityand sometimes coughing or fluid buildup.

Mitral Valve Prolapse (MVP)

In mitral valve prolapse, the valve leaflets bulge backward during contraction.
Many people with MVP have no symptoms and no serious leakage. When leakage is present, MVP can be a
cause of mitral regurgitation and may lead to palpitations or fatigue in some individuals.

Tricuspid and Pulmonary Valve Disease

The tricuspid valve and pulmonary valve manage blood flow on the
right side of the heart (the “send blood to the lungs” side). These valve problems can occur due to
congenital conditions, lung disease, or heart enlargement.

• Tricuspid regurgitation: often related to right heart enlargement; can cause leg
  swelling, abdominal swelling, and fatigue.
• Pulmonary stenosis/regurgitation: more commonly linked to congenital heart disease,
  though it can appear in adults depending on medical history.

What Causes Valvular Heart Disease?

Valve disease can be present at birth or develop over time. Common causes include:

Common Causes and Risk Factors

• Age-related degeneration (calcification and stiffening, especially the aortic valve)
• Congenital valve differences (like a bicuspid aortic valve)
• Rheumatic heart disease (after rheumatic fever, still seen in some populations)
• Infective endocarditis (infection of the heart lining/valves)
• Heart attack or cardiomyopathy that changes the heart’s shape and valve mechanics
• Connective tissue disorders (e.g., Marfan syndrome) that affect valve structure
• Radiation therapy to the chest (in some cases)

Sometimes the “cause” is simply that the heart has been doing its job for decades. Valves open and
close about 100,000 times per day. Even high-quality hardware gets wear and tear.

How Valvular Heart Disease Is Diagnosed

Diagnosis usually starts with a medical history and physical exam. A clinician may hear a
heart murmura whooshing sound caused by turbulent blood flow. But the most important
step is confirming what’s happening with imaging.

Key Tests

• Echocardiogram (echo): the main test for valve structure, severity of stenosis or
  regurgitation, and heart function.
• Transesophageal echocardiogram (TEE): a more detailed echo using a probe in the
  esophagus (often for surgical planning or clearer images).
• Electrocardiogram (ECG): checks rhythm issues like atrial fibrillation.
• Chest X-ray: can show heart enlargement or lung fluid.
• Cardiac CT or MRI: can help define anatomy and guide procedural planning.
• Cardiac catheterization: sometimes used to confirm pressures, evaluate coronary
  arteries, or when noninvasive tests don’t match symptoms.

Many cardiology teams track valve disease over time, because severity can progress. You might hear
terms like mild, moderate, or severeor see measurements like valve area, pressure gradients, or
regurgitation fraction. Translation: they’re quantifying how hard your heart is working to keep
things moving.

Treatment Options for Valvular Heart Disease

Treatment depends on the valve involved, whether it’s stenosis or regurgitation, symptom severity,
and how the heart is responding. Some people only need monitoring for years. Others need a procedure
sooner to prevent long-term damage.

1) Watchful Waiting (a.k.a. “Active Surveillance”)

If valve disease is mild or moderate and you feel well, your care plan may focus on:
routine follow-ups, repeat echocardiograms, and managing risk factors like high blood pressure.
This isn’t “doing nothing”it’s timing treatment so it’s neither too early nor too late.

2) Medications (Helpful, But Not a Valve Fix)

Medications generally do not repair a damaged valve, but they can reduce symptoms and lower
strain on the heart. Depending on your situation, clinicians may use:

• Diuretics to reduce fluid buildup and ease shortness of breath
• Blood pressure medicines (such as ACE inhibitors/ARBs) when appropriate
• Beta-blockers or other rate-control medicines for rhythm issues
• Anticoagulants (blood thinners) for atrial fibrillation or mechanical valves

A key nuance: in some forms of severe stenosis, certain blood pressure medicines may need careful
use because the heart is already pumping through a tight “gate.” That’s why medication plans for
valve disease should be tailorednot DIY’d from internet comments, even if the comments are written
with great confidence and five exclamation points.

3) Procedures and Surgery

When a valve problem becomes severe, causes symptoms, or begins damaging the heart, procedures may
be recommended. Many decisions are made by a heart team (cardiologists, surgeons,
imaging specialists) to match the safest and most effective option to the patient.

Valve Repair

Repair keeps your own valve and may be preferred when feasibleespecially for certain types of mitral
regurgitation. Repair options can include reshaping valve tissue, supporting it with an annuloplasty
ring, or other techniques to improve closure.

Valve Replacement

Replacement swaps the faulty valve for a new one. Valves may be:

• Mechanical valves: durable but usually require long-term anticoagulation.
• Tissue (bioprosthetic) valves: often avoid long-term anticoagulation but may wear
  out sooner than mechanical valves (timing varies by age and other factors).

Transcatheter (Minimally Invasive) Valve Therapies

In many cases, valves can be treated through catheters placed through a blood vesselmeaning smaller
incisions and, for some patients, faster recovery.

• TAVR/TAVI (Transcatheter Aortic Valve Replacement/Implantation): a catheter-based
  replacement option for many people with severe aortic stenosis, including across a range of surgical
  risk profiles.
• Balloon valvuloplasty: may be used in select stenosis cases (more common in certain
  mitral stenosis scenarios or specific patient situations).
• TEER (Transcatheter Edge-to-Edge Repair): a catheter-based repair approach for select
  people with severe mitral regurgitation who meet anatomy and clinical criteria.

What Happens If Severe Aortic Stenosis Is Left Untreated?

Severe symptomatic aortic stenosis is especially high risk without valve intervention.
That’s why new or worsening symptomschest pressure, fainting, significant shortness of breathshould
trigger prompt evaluation.

Living Well With Valve Disease

Day-to-day life with valvular heart disease often comes down to smart monitoring and heart-healthy
habits. Your clinician might recommend:

• Regular follow-ups and echocardiograms as advised
• Blood pressure control and cholesterol management when appropriate
• Physical activity tailored to your symptoms and valve severity
• Limiting excess sodium if you retain fluid
• Vaccines as advised (to reduce infection-related strain)
• Dental care and oral hygienebecause mouth bacteria can enter the bloodstream

Infective Endocarditis Prevention: The Dental Question

You may hear about antibiotics before dental work. Current guidance generally reserves preventive
antibiotics for people at highest risk of poor outcomes from infective endocarditis
(for example, certain prosthetic valves or specific prior heart infections). The details matter, so
this is a “follow your clinician’s guidance” situationrather than a one-size-fits-all rule.

Frequently Asked Questions

Can valve disease go away on its own?

Some mild issues may stay stable for years, but structural valve disease typically doesn’t “reverse.”
Treatment focuses on monitoring, symptom control, and intervention when benefits outweigh risks.

If I feel fine, do I still need follow-ups?

Often, yes. Some valve conditions remain quiet while the heart adapts in the background. Regular
echocardiograms can catch progression before permanent heart changes occur.

Is a heart murmur always dangerous?

Not always. Some murmurs are “innocent,” but a murmur can also be the first clue of valve disease.
If a murmur is new or accompanied by symptoms, it’s worth evaluating.

Real-Life Experiences With Valvular Heart Disease (Patient & Family Perspectives)

Medical descriptions are usefulstenosis, regurgitation, gradients, valve areabut people don’t live
in measurement units. They live in moments: the walk that suddenly feels too long, the stairs that
used to be “nothing,” the fatigue that doesn’t match the day. Below are common experiences reported
by patients and families. These are illustrative composites, not a substitute for medical care,
but they reflect what many people describe on the road from symptoms to treatment.

“I thought I was just out of shape.”

This is one of the most common stories. People often adapt gradually: they walk slower, park closer,
skip activities, or blame age, stress, or “a busy season.” In aortic stenosis or significant mitral
regurgitation, the heart may compensate for a long time. That can make the first noticeable symptom
feel confusingespecially if it’s subtle breathlessness rather than dramatic chest pain.

Diagnosis day feels strangely ordinary (until it doesn’t)

Many patients describe the echocardiogram as almost anticlimactic: gel, a probe, a screen, and then
a follow-up conversation that suddenly turns life into a planrepeat testing, medication changes, or
referral to a valve specialist. Some people feel relief (“Finally, a reason!”). Others feel anxiety
because the condition sounds serious even if they don’t feel terrible. Both reactions are normal.

Fatigue can be the loudest symptom

Movies love dramatic symptoms. Real life often hands you fatigue: the kind that makes errands feel
like a full workout. With valve leakage, the heart may be moving blood in circlesforward, then a
little backwardso the body gets less efficient delivery of oxygen. People describe needing naps,
avoiding social plans, or feeling “winded” by tasks that used to be routine.

Living with a murmur becomes “background noise”

Some patients have known about a murmur for years. Over time, it can feel like a quirky trivia fact
rather than a health issueuntil symptoms change or the echo shows progression. Many people say the
hardest part is remembering that “no symptoms” doesn’t always mean “no progression,” which is why
follow-up appointments matter even when life feels normal.

Decision-making is emotionaland surprisingly practical

When intervention is recommended, the decision often includes practical questions that aren’t in
textbook diagrams: “How much time off work will I need?” “Will I be able to drive?” “What does
recovery look like?” “Do I need blood thinners forever?” People commonly feel torn between wanting
the most durable option and wanting the simplest day-to-day routine. Talking with a cardiology team,
asking for clear comparisons, and involving family members or trusted friends can help.

Recovery is usually measured in small victories

After valve repair or replacementwhether surgical or transcatheterpatients often describe progress
in milestones: walking to the mailbox without stopping, sleeping flat again, climbing stairs without
bargaining, or noticing their ankles aren’t swollen by evening. Many people say cardiac rehab (when
offered and appropriate) helps rebuild confidence, not just stamina. And yes, patients also report a

surprisingly emotional moment: realizing they forgot about their breathing for a whole afternoon.
That’s the kind of “symptom improvement” no chart fully captures.

If any of these experiences sound familiar, the next step isn’t panicit’s evaluation. Valve disease
is treatable, and timing matters. The best outcomes often come from getting the right diagnosis
early, tracking progression, and choosing the right intervention at the right moment.
