Congenital valvular heart disease means one or more heart valves were formed abnormally before birth. The valve can be too tight (stenosis), too leaky (regurgitation), under-developed, malformed (for example, a bicuspid aortic valve with two leaflets instead of three), or positioned abnormally. Because valves direct blood flow, these problems change pressure and flow inside the heart and lungs. Some children have no symptoms for years; others have trouble soon after birth. Many people live normal lives after appropriate monitoring, catheter procedures, or surgery, but lifelong follow-up is essential because the heart and valves change with time. American College of Cardiology+2American College of Cardiology+2

Congenital valvular heart disease means a heart valve is formed in an unusual way before birth. The baby is born with this problem. A heart valve acts like a small door that lets blood move forward and stops it from moving backward. If a valve is too tight, blood has trouble going through (this is called stenosis). If a valve does not close well, blood leaks backward (this is called regurgitation or insufficiency). Some people have both problems at the same time. The abnormal valve can be in any of the four valves of the heart: the aortic valve, mitral valve, pulmonary valve, or tricuspid valve. The problem can be mild, moderate, or severe. It can stay the same for years or slowly get worse. Some people feel fine for a long time. Others have symptoms in childhood. Many people need follow-up for life with a heart specialist who knows adult congenital heart disease.

Congenital valvular heart disease means a baby is born with one or more heart valves that formed abnormally during pregnancy. A valve may have the wrong shape, the wrong number of leaflets (flaps), be too tight (stenotic), too leaky (regurgitant), or be placed in an unusual position. These valve changes alter normal one-way blood flow and can strain the heart over time. Doctors usually find CVHD with echocardiography (heart ultrasound), which shows valve anatomy and how blood moves across the valve. Echocardiography is the first-line and core test for valvular disease and for most congenital heart problems. PMC+2Rev Esp Cardiol+2

Another names

Doctors use several names for the same idea. You may hear: congenital valve disease, congenital valvular malformation, congenital valvular stenosis, congenital valvular regurgitation, bicuspid aortic valve, congenital aortic stenosis, congenital pulmonary stenosis, parachute mitral valve, cleft mitral valve, Ebstein anomaly (tricuspid problem), and dysplastic valves. All of these are types of congenital valvular heart disease.

Types

By valve involved

Aortic valve (left heart, outflow to body).
The aortic valve may have two leaflets instead of three (bicuspid aortic valve). This is the most common congenital valve defect. It can become tight (aortic stenosis) or leaky (aortic regurgitation). The valve tissue can be thick and stiff (dysplastic). The aorta can also be enlarged in people with bicuspid valves.

Mitral valve (left heart, inlet from lungs).
The mitral valve may have a cleft (a gap in a leaflet), extra tissue, or be shaped so that all chordae attach to one papillary muscle (parachute mitral valve). The valve may be too small (mitral stenosis) or leaky (mitral regurgitation). Some people have congenital mitral valve prolapse, where the leaflet bows back into the atrium.

Pulmonary valve (right heart, outflow to lungs).
Pulmonary valve stenosis is common in children. The valve leaflets are thick or fused, so blood has trouble reaching the lungs. The valve can also be leaky after balloon or surgical treatment.

Tricuspid valve (right heart, inlet from body).
In Ebstein anomaly, the tricuspid valve is lower than normal and the leaflets are abnormal. This causes leakage and right-sided heart problems. Other people have tricuspid dysplasia (abnormal tissue) with stenosis or regurgitation.

By function

Stenosis.
The valve is narrow. The heart must push harder to move blood forward. This can make the heart muscle thick over time.

Regurgitation (insufficiency).
The valve leaks. Blood falls back the wrong way. The heart must pump extra to keep up. This may enlarge the heart.

Mixed lesions.
Some people have both narrowing and leakage. Treatment plans look at which problem is more severe.

By timing and complexity

Isolated valve lesion.
Only one valve is affected. Many children do well with simple procedures.

Valve lesion with other heart defects.
Sometimes the valve problem comes with a hole in the heart (ASD, VSD), coarctation of the aorta, or more complex congenital heart disease. Care needs a team with congenital expertise.

By valve and pattern

Aortic valve (AV) types

Bicuspid aortic valve (BAV): the valve has two leaflets instead of three. It may be tight (stenotic), leaky, or both. BAV is common (about 1% of people) and can run in families. PMC
Congenital aortic stenosis: the aortic valve opening is too small at birth, making the left ventricle pump harder. PMC

Pulmonary valve (PV) types

Congenital pulmonary valve stenosis: the valve from right ventricle to lungs is tight; it often appears in Noonan syndrome and can be “dysplastic” (abnormally thick leaflets). PMC+1

Mitral valve (MV) types

Parachute mitral valve / supravalvar mitral ring / congenital mitral stenosis: abnormal chordae or tissue rings narrow the valve; a cleft mitral leaflet can cause leakage (regurgitation). PMC

Tricuspid valve (TV) types

Ebstein anomaly: the septal and posterior leaflets are displaced downward into the right ventricle, causing regurgitation and right-sided chamber changes. Certain maternal exposures (like lithium) have been linked to a modestly increased risk. New England Journal of Medicine

Mixed patterns

Some patients have more than one congenital valve problem, or a valve problem plus other congenital heart lesions. Echocardiography and, if needed, cardiac MRI help map the full picture. PMC

Causes and risk factors

Congenital means “formed during pregnancy,” so “causes” here are factors that raise the chance a baby’s heart valves form abnormally. Not every case has an identifiable cause.

Genetic variants in NOTCH1 (BAV): mutations in the NOTCH1 pathway disrupt valve development and are the best-established genetic link to bicuspid aortic valve and early valve calcification. Frontiers+2PMC+2
Family history of BAV or congenital valve disease: BAV often clusters in families, reflecting heritable pathways like NOTCH signaling. PMC
Noonan syndrome: a genetic condition (often RAS-MAPK pathway genes) strongly associated with congenital pulmonary valve stenosis. PMC+1
Turner syndrome: increases risk for left-sided lesions, including bicuspid aortic valve and aortic coarctation; valves may be affected. PMC
Williams–Beuren syndrome: elastin gene deletion causing supravalvar aortic stenosis; valvular involvement may coexist. PMC
Marfan or Loeys–Dietz syndromes: connective-tissue disorders that predispose to valve prolapse or dysfunction. PMC
Trisomy 21 (Down syndrome): mainly associated with atrioventricular canal, but valvular defects can occur within that spectrum. PMC
22q11.2 deletion (DiGeorge spectrum): conotruncal defects dominate; valvular anomalies may accompany. PMC
Maternal rubella infection (first trimester): classic cause of congenital heart defects, especially PDA and peripheral pulmonic stenosis; valvular and pulmonary arterial lesions are well described. jpeds.com+2Brieflands+2
Maternal lithium exposure (early pregnancy): modern data show a modest increase in risk of cardiac malformations (including Ebstein anomaly), far lower than early estimates. New England Journal of Medicine+1
Maternal diabetes (pre-gestational): raises overall congenital heart defect risk via altered embryonic signaling; valve defects may be part of the phenotype. Wiley Online Library
Retinoic acid (isotretinoin) exposure: linked to outflow tract and valve anomalies through neural crest effects. Wiley Online Library
Alcohol (fetal alcohol spectrum): associated with congenital heart defects; some involve valves. Wiley Online Library
Valproate and certain antiepileptics: associated with congenital malformations including cardiac defects. Wiley Online Library
Maternal phenylketonuria (poorly controlled): high phenylalanine levels are teratogenic and increase CHD risk. Wiley Online Library
Assisted reproductive technologies / subfertility: slight increase in CHD risk reported; some cases include valves. Wiley Online Library
Advanced maternal age: small risk increase for CHD overall, including valvular lesions in some studies. Wiley Online Library
Consanguinity (parents are related): increases chance of recessive genetic conditions affecting heart development. Wiley Online Library
Intrauterine infections beyond rubella (e.g., some first-trimester infections): emerging evidence links maternal infection and CHD risk overall; patterns vary. OUP Academic
Unknown/idiopathic: in many patients, a single clear cause is not found despite evaluation; gene–environment interactions likely play a role. PMC

Common symptoms

Symptoms vary with the valve, the severity of narrowing or leak, and age. Some babies have no symptoms and are diagnosed by a murmur. Others develop signs as they grow.

Heart murmur heard by a clinician: turbulent flow across a tight or leaky valve makes a characteristic sound. Murmurs guide which valve may be affected. Rev Esp Cardiol
Shortness of breath (dyspnea): tight or leaky valves increase pressures and fluid in the lungs or reduce forward output, causing breathlessness with activity or feeding. PMC
Poor feeding and failure to thrive (infants): babies tire easily with feeding when the heart works too hard. PMC
Easy fatigue and exercise intolerance: school-age children and adults may notice reduced stamina. PMC
Cyanosis (bluish color), especially with severe right-sided lesions: reduced oxygenated blood flow can cause a blue tinge to lips or fingers. PMC
Chest pain or chest pressure (older children/adults): occurs when the heart muscle is overworked or oxygen supply is limited. PMC
Palpitations (awareness of heartbeat): valve disease can stretch chambers and trigger rhythm problems. PMC
Fainting or near-fainting (syncope): severe stenosis (especially aortic) can limit blood to the brain during exertion. PMC
Swelling of legs or belly (edema/ascites): right-sided valve disease can cause fluid buildup. PMC
Rapid breathing (tachypnea) in infants: a sign the heart and lungs are strained. PMC
Recurrent respiratory infections: congestion and poor lung perfusion may contribute. PMC
Poor growth and delayed milestones (untreated severe disease): long-term low output and high energy use hinder growth. PMC
Liver enlargement (hepatomegaly): from right-sided pressure overload and venous congestion. PMC
No symptoms at all: many people—especially with BAV—are first diagnosed by an incidental murmur or screening echo. PMC
Pregnancy-related symptoms unveiling disease in adults: increased blood volume can reveal previously silent valve problems. PMC

Diagnostic tests

A) Physical examination

Inspection of breathing and color: doctors look for fast breathing, chest retractions, and bluish lips or nails that suggest low oxygen or heart strain. Rev Esp Cardiol
Pulse and blood pressure in arms and legs: differences can hint at left-sided obstruction; rate and rhythm provide rhythm clues. Rev Esp Cardiol
Palpation of the chest (precordium): a heaving impulse may suggest pressure overload from a tight valve. Rev Esp Cardiol
Auscultation (listening with a stethoscope): specific murmur timing and location point to which valve is involved (e.g., right upper sternal border for aortic, left upper for pulmonary). Rev Esp Cardiol
Checking for liver enlargement and leg swelling: signs of right-sided valve disease with congestion. Rev Esp Cardiol

B) Bedside/manual maneuvers

Valsalva maneuver: straining reduces venous return and changes many murmurs; it helps differentiate types. Rev Esp Cardiol
Squatting/standing: squatting raises venous return and afterload; standing does the opposite. The change in murmur intensity helps identify the lesion. Rev Esp Cardiol
Handgrip (isometric exercise): increases afterload; regurgitant murmurs often grow louder. Rev Esp Cardiol
Deep inspiration: increases right-sided heart sounds like tricuspid/pulmonic murmurs. Rev Esp Cardiol
Passive leg raise: boosts venous return transiently and can alter murmur intensity. Rev Esp Cardiol

C) Lab and pathological tests

Genetic testing when indicated: used if syndromic features or strong family history exist (e.g., NOTCH1 in families with BAV; RAS-MAPK genes in Noonan). Results guide counseling and screening of relatives. PMC+1
BNP/NT-proBNP: blood tests that rise when the heart is under strain; they support the assessment of severity and heart failure status. PMC
Routine metabolic and infection screening in infants: if a congenital infection (like rubella) is suspected, serology and public-health case definitions apply. www-new.cdc.gov
Pathology (rarely needed in living patients): when valves are repaired/replaced, surgical specimens confirm the congenital pattern under the microscope. Mayo Clinic Proceedings

D) Electrodiagnostic tests

Electrocardiogram (ECG): shows chamber enlargement, conduction problems, or rhythm disturbances caused by valve disease burden. Rev Esp Cardiol
Ambulatory ECG (Holter/patch): records irregular rhythms or palpitations over 1–14 days. PMC
Exercise testing (older children/adults): measures capacity and blood pressure response; helps judge severity and timing for treatment. PMC

E) Imaging tests

Transthoracic echocardiography (TTE): the main, first-line test. It shows leaflet number, motion, thickness, valve opening area, leak, and pressure gradients, using 2D/3D views and Doppler. PMC+1
Transesophageal echocardiography (TEE): an ultrasound probe in the esophagus gives closer views when TTE is limited or when surgical planning is needed. PMC
Fetal echocardiography (during pregnancy): detects many valve defects before birth in high-risk pregnancies or when screening suggests a problem. Wiley Online Library
Cardiac MRI (CMR): maps valve anatomy, flows, and ventricular function without radiation; useful for right-sided lesions and complex anatomy. PMC
Cardiac CT angiography: excellent for aortic root and valve calcification, coronary anatomy, and surgical planning when echo is not enough. PMC
Chest X-ray: gives a quick look at heart size and lung vessels; supportive, not definitive. Rev Esp Cardiol
Cardiac catheterization: measures pressures directly and can treat some lesions (e.g., balloon valvuloplasty for pulmonary stenosis) in the same session. BVS Salud Documentation

20 drug treatments (FDA-labeled sources from accessdata.fda.gov)

Important: medications support symptoms/complications (heart failure, arrhythmia, PH, thrombosis) and do not “fix” a malformed valve; definitive therapy is catheter or surgery when indicated. Doses below are typical adult starting ranges unless pediatric labeling exists—clinicians individualize by age, weight, kidney/liver function, and goals.

Furosemide (loop diuretic)
Purpose: Reduce fluid overload (edema, breathlessness).

Antibiotics for infective endocarditis prophylaxis (selected patients only)
Purpose: For the highest-risk groups before certain dental procedures (e.g., prior IE, prosthetic valves).
Mechanism: Single pre-procedure dose (e.g., amoxicillin) reduces bacteremia risk; clindamycin is no longer recommended due to adverse reactions. Follow AHA tables. Ada.org

⚠️ Drug choices and doses must be individualized by a cardiologist—children, pregnancy, kidney/liver disease, mechanical vs bioprosthetic valves, and rhythm/PH status all change what’s safe and effective. American College of Cardiology

10 dietary molecular supplements (supportive—not substitutes for medical/surgical care)

Evidence for supplements in CVHD is limited; any use should be physician-guided to avoid interactions (especially with warfarin/antiarrhythmics). The focus remains a heart-healthy diet.

Omega-3 fatty acids (fish oil/DHA-EPA): may modestly lower triglycerides and inflammation; potential antiplatelet effect—caution with anticoagulants. AHA Journals
Coenzyme Q10: mitochondrial cofactor sometimes used for statin-associated myalgias and experimental HF support; interactions are possible. AHA Journals
Vitamin D: replete if deficient; supports bone/muscle health; avoid excess (hypercalcemia/arrhythmias). AHA Journals
Magnesium: correct documented low Mg to reduce ectopy/cramps; excess can depress reflexes/pressure in renal impairment. AHA Journals
Thiamine (B1): replete in patients on chronic high-dose diuretics with low intake; supports myocardial metabolism. AHA Journals
Iron (for proven iron-deficiency): treat deficiency to improve energy; avoid unnecessary iron; monitor ferritin/transferrin saturation. AHA Journals
Folate/B12 (if low): correct macrocytosis and support hematologic health; necessary in women of childbearing potential. AHA Journals
Potassium (only if low and if safe): replace under supervision, especially with loops; avoid if on MRAs/ACEi/ARNI with high K⁺ risk. AHA Journals
Sodium restriction (dietary measure): not a supplement, but a key “molecular” intake control that lowers fluid retention. AHA Journals
Protein-adequate, plant-forward dietary pattern: supports growth/healing in children and healthy weight in adults. AHA Journals

“Immunity booster / regenerative / stem-cell drugs” (6)

There are no FDA-approved stem-cell drugs to repair congenital valves. Care is surgical/catheter-based when needed, supported by guideline-directed medical therapy. Safe immune support is vaccination and nutrition. Any product claiming to “regenerate” valves should be avoided unless part of an ethically approved clinical trial at a recognized center. American College of Cardiology
That said, here are six legitimate medical strategies often mis-labeled as “immune/regenerative,” explained clearly:

Routine vaccinations (flu, COVID-19, others as indicated): reduce infection-triggered decompensation. American College of Cardiology
Iron/folate/B12 repletion when deficient: supports blood-forming tissues and oxygen delivery. AHA Journals
Rehabilitation/exercise therapy: improves cardiac efficiency (“functional remodeling”), not valve regrowth. American College of Cardiology
Nutritional optimization: adequate calories/protein in infants/children with high cardiac energy needs. American College of Cardiology
Pulmonary vasodilator therapy in PAH (specialist-directed): improves vessel function, not “regeneration.” FDA Access Data+1
Definitive repair/replacement (surgery/cath): true structural correction when anatomy requires it. (See surgeries below.) AHA Journals

5 surgeries/procedures (what they are & why done)

Balloon valvotomy/valvuloplasty (catheter-based)
What: A catheter with a balloon is passed across a tight valve (often pulmonary or aortic in children) and inflated to split fused leaflets.
Why: To relieve stenosis without open surgery when anatomy is favorable. American College of Cardiology
Valve repair (surgical)
What: Surgeon reshapes leaflets, removes extra tissue, or adds support rings to improve closing.
Why: Preferred when feasible, especially for leaking valves, to preserve the native valve and avoid prosthetic complications. AHA Journals
Valve replacement (bioprosthetic or mechanical)
What: Diseased valve is replaced. Mechanical valves are durable but require warfarin; bioprostheses avoid lifelong warfarin but may wear out.
Why: Used when repair is not possible or durable. AHA Journals
Transcatheter valve implantation (e.g., pulmonary or aortic in selected anatomies)
What: A collapsible valve is delivered via catheter and expanded inside a failing native or prior surgical valve.
Why: Avoids open-heart surgery in suitable patients and allows future “valve-in-valve” strategies. AHA Journals
Combined procedures for complex CHD
What: Address valve plus associated lesions (e.g., subaortic obstruction, arch repair) in a single operation.
Why: Optimizes blood flow and ventricular workload in one stage. American College of Cardiology

15 FAQs (clear & brief)

1) Can medicines cure a congenital valve defect?
No. Medicines treat symptoms and complications (fluid overload, high lung pressure, arrhythmias, clots). Structural problems are corrected with catheter or surgery when needed. AHA Journals

2) Will I definitely need surgery?
Not always. Mild lesions may only need monitoring. Timing depends on symptoms, valve severity, and heart changes on imaging. American College of Cardiology

3) Is dental antibiotic prophylaxis routine?
No. Only the highest-risk groups (e.g., prosthetic valves, prior IE) need antibiotics before certain dental procedures. Good daily oral hygiene is crucial for everyone. Ada.org

4) Are DOACs safe for mechanical valves?
No. Mechanical valves require warfarin with INR monitoring; DOACs are not used for this indication. American College of Cardiology

5) Can I play sports?
Many can, especially with mild disease. Your team sets safe limits based on lesion type/severity and rhythm/PH status. American College of Cardiology

6) What happens during balloon valvuloplasty?
A catheter balloon is inflated across a tight valve to widen it; recovery is often faster than open surgery when anatomy is favorable. American College of Cardiology

7) How long do replacement valves last?
Mechanical valves are very durable but require warfarin. Bioprosthetic valves may wear out over years; transcatheter “valve-in-valve” can sometimes extend durability. AHA Journals

8) How often will I need tests?
It varies. Your cardiologist sets intervals (often 6–24 months) based on severity, symptoms, and life stage (childhood, pregnancy, aging). American College of Cardiology

9) Can pregnancy be safe?
Many do well with planning and specialist care. Some lesions need treatment before pregnancy; medications/anticoagulation may change. American College of Cardiology

10) What are signs of infective endocarditis?
Fever, chills, fatigue, new/worsening murmur, or signs of emboli. Get urgent assessment—IE can be life-threatening but early treatment helps. Ada.org

11) Why do I need lifelong care if I feel fine?
Valve and heart changes can be silent for years. Follow-up catches problems early when treatment is safer and more durable. American College of Cardiology

12) Is “stem-cell therapy” available?
No approved stem-cell drugs repair congenital valves. Avoid unproven clinics; ask about clinical trials at recognized centers. American College of Cardiology

13) What if I need MRI with a mechanical valve?
Most modern valves are MRI-conditional, but the imaging team confirms safety before scanning. Always carry implant details. American College of Cardiology

14) Can PAH medicines help my valve disease?
Only if you truly have pulmonary arterial hypertension and a specialist confirms it. These are potent, pregnancy-restricted drugs with monitoring. FDA Access Data

15) Who should coordinate my care?
An adult congenital heart disease (ACHD) or pediatric congenital cardiology team—especially for procedures, pregnancy, or complex lesions. AHA Journals
