Names & Terms You Will Hear
Plain-language meanings for the terms your care team may use.
| Term | Meaning |
|---|---|
| Paravalvular leak (PVL) | A leak through a gap between a replacement valve and the tissue ring around it. |
| Paravalvular regurgitation | The same thing. 'Regurgitation' means blood flowing backward. |
| Para- (prefix) | Means 'beside' or 'around.' The leak is beside the valve, not through it. |
| Sewing ring | The fabric rim of a surgical valve. The surgeon stitches it to your tissue ring. |
| Annulus | Your own tissue ring that the valve sits in. |
| Prosthetic valve | An artificial replacement valve — tissue or mechanical. |
| Hemolysis | Red blood cells breaking apart. The leak jet can shear them. |
| Transcatheter closure | Plugging the gap with a device sent through a thin tube. No open surgery. |
| Occluder / vascular plug | The small device used to fill the gap. |
| Endocarditis | Infection of a heart valve. It must be ruled out as a cause of a new leak. |
| Heart Team | Your cardiologist and heart surgeon. They decide the best fix together. |
Around, not through. The valve's own leaflets may open and close perfectly. A paravalvular leak is in the gap beside the valve, where the sewing ring meets your tissue ring. This is different from a leak through a worn-out valve — see Dr. Ali's Living With a Prosthetic Valve guide.
What Is Paravalvular Leak?
- A paravalvular leak (PVL) is a gap between an artificial (replacement) valve and the natural tissue ring it is sewn or seated into.
- Blood leaks around the valve through this gap — not through the valve's normal opening. That is the key difference from a worn-out valve.
- It can happen after surgical valve replacement or after TAVR (a catheter-placed valve).
- Most leaks are small. They cause no symptoms and just need watching with an echocardiogram.
- A larger leak causes two main problems: heart failure symptoms and hemolysis (red blood cells breaking apart).
- A new or growing leak always prompts a check for infection (endocarditis) as a possible cause.
Why It Matters
- A bigger leak makes your heart re-pump the same blood over and over. Over time this can weaken the heart and cause heart failure.
- The narrow, high-speed jet through the gap can shear red blood cells. This causes anemia — tiredness, pallor, and dark urine.
- PVL is a recognized complication of valve replacement. It is found in about 5 to 15% of mitral (surgical) valve replacements (per PubMed-indexed reviews).
- Most small leaks never cause trouble. The point of follow-up is to catch the few that grow early.
- When a leak is significant, modern transcatheter closure can fix it without another open-heart operation in many patients.
Risk Factors
Knowing your personal risks helps your care team take extra precautions.
| Risk Factor | Why It Increases Risk |
|---|---|
| Heavy valve-ring calcium | Hard, bumpy calcium keeps the sewing ring from sealing flat against the tissue. |
| Infection (endocarditis) | Infection can eat away tissue at the sewing ring and open a gap. Must always be ruled out. |
| Mitral position | Leaks are more common around mitral valves than aortic ones. |
| Larger or repeat valve surgery | Scarred or previously operated tissue holds stitches less reliably. |
| Technical and tissue factors | Stitch spacing, ring shape, and fragile tissue can all leave a small gap. |
| After TAVR | A catheter valve may not seal perfectly against a heavily calcified ring. |
Treatment Options
Shown in English for your safety — this section is not automatically translated. Confirm with your doctor or call the office.
- Small leak, no symptoms: watch it. A yearly echocardiogram tracks the leak and your heart size. No procedure is needed.
- Significant leak (symptoms or hemolysis): close the gap. The modern first choice at experienced centers is a transcatheter closure.
- Transcatheter PVL closure sends a thin tube (catheter) to the gap and places a small plug (occluder) to fill it. No chest opening. Shorter recovery.
- Repeat surgery is used when transcatheter closure is not suitable, when there are several large gaps, or when other valve work is needed at the same time.
- Treat any infection. If endocarditis caused the leak, antibiotics (and often surgery) come first.
- Heart Team review is required. Your cardiologist and surgeon weigh closure vs surgery for your anatomy and risk.
Transcatheter Closure vs Repeat Surgery
| Feature | Transcatheter Closure | Repeat Surgery |
|---|---|---|
| Access | Thin tube (catheter). No chest cut. | Open chest again. |
| What it does | Plugs the gap with an occluder device. | Re-stitches or replaces the valve. |
| Recovery | Short — often 1 to 2 days. | Longer — weeks. |
| Best for | Most significant leaks; high surgical risk. | Several or very large gaps; other valve work needed. |
| Modern role | First choice at experienced centers. | The backup when closure is unsuitable. |
Risks, Benefits, and Alternatives

Every choice has trade-offs. Use this table to start the shared decision conversation with your care team.
| Option | Risks | Benefits | Alternatives |
|---|---|---|---|
| Watchful waiting (small leak) | A leak can grow silently. Needs yearly echo and steady follow-up. | No procedure and no procedure risk. Most small leaks never cause trouble. | Move to closure if the leak grows or symptoms or anemia start. |
| Transcatheter PVL closure | Leak may not fully seal; a second device may be needed. Small risks: bleeding, stroke, device shift. Rarely the device blocks the valve. | No chest opening. Shorter stay and recovery. High device-success rate. Often improves both symptoms and hemolysis. | Repeat surgery if closure is unsuitable. Watching if the leak is small. |
| Repeat valve surgery | Open-heart re-operation. Higher risk than the first surgery. Longer recovery. | Can fully fix several or large gaps. Lets the surgeon replace the valve or treat infection at the same time. | Transcatheter closure if anatomy allows and risk is high. |
| Treat infection first (if endocarditis) | Delays closing the gap. Infection itself is serious. | Stops the cause. Clearing infection is required before any durable repair. | Closure or surgery after the infection is controlled. |
Leak Severity, Symptoms, and the Usual Action
| Severity | What You May Feel | Usual Action |
|---|---|---|
| Trace / mild | Nothing. Found only on echo. | Watch with a yearly echocardiogram. |
| Moderate | Mild breathlessness or tiredness; mild anemia. | Closer follow-up; plan a fix if it grows or symptoms start. |
| Severe | Clear heart failure or marked anemia / dark urine. | Fix it: transcatheter closure first; surgery as backup. |
| Any new leak | Possible fever or feeling unwell. | Rule out infection (endocarditis) before anything else. |
Common Misconceptions
| Myth | Reality |
|---|---|
| A paravalvular leak means my replacement valve failed. | Not usually. The valve itself often works fine — the leak is in a gap beside it, where the valve meets your tissue ring. |
| Any leak around the valve needs surgery right away. | No. Most leaks are small and only need watching. Only a significant leak with symptoms or hemolysis needs a fix. |
| A leak around the valve is the same as a worn-out valve. | These are different problems. A worn valve leaks through the valve; a paravalvular leak goes around it. The fixes differ. |
| Fixing a leak always means another open-heart operation. | No. Many leaks can now be closed with a catheter and a small plug — no chest opening — at experienced centers. |
| My anemia can't be from a heart valve. | It can. A narrow leak jet shears red blood cells. This is a known cause of anemia after valve replacement. |
| If I feel fine, the leak doesn't matter. | A leak can grow before you feel it. That is exactly why your team keeps checking with echo, even when you feel well. |
| A new leak is never caused by infection. | A new or growing leak always prompts a check for endocarditis. Infection can open a gap and must be treated first. |
How the valve was placed: a paravalvular leak can follow open surgical valve replacement or a catheter-placed TAVR valve. It is a separate problem from a leaky mitral valve treated with MitraClip / TEER. A new leak always prompts a check for infective endocarditis.
Possible Complications
Knowing what can go wrong helps you spot problems early. Most complications are uncommon, especially with treatment.
| Where / What | What Can Happen |
|---|---|
| Heart (congestion) | A big leak forces the heart to re-pump blood. This can cause heart failure: breathlessness, fatigue, and swelling. |
| Blood (hemolysis) | The narrow jet shears red blood cells, causing anemia — tiredness, pale skin, and dark (cola-colored) urine. |
| Kidneys | Severe, ongoing hemolysis can rarely strain the kidneys from the load of broken red cells. |
| Valve / device | During closure, a plug can rarely shift or press on the valve. The Heart Team plans to avoid this. |
| Infection (endocarditis) | Infection can both cause a leak and be a danger on its own. It must be found and treated. |
| Rhythm and blood pressure | A failing, overloaded heart can trigger atrial fibrillation and low blood pressure. |
Two Ways a Leak Causes Trouble
- 1. Heart failure from extra volume. A significant leak sends blood backward each beat. The heart must re-pump the same blood, so it works harder.
- Over time the chamber stretches and weakens. Fluid backs up into the lungs and body.
- You feel breathless (worse lying flat), tired, and notice swelling in the legs or belly.
- 2. Hemolysis from a shearing jet. The leak forces blood through a narrow gap at high speed. This shear force breaks red blood cells apart.
- Broken cells mean anemia: tiredness, pale skin, and dark (tea- or cola-colored) urine from released pigment.
- Severe, ongoing hemolysis can rarely strain the kidneys. Even without big heart-failure symptoms, hemolysis alone can be a reason to fix the leak.
Finding It — Echo, TEE, and Ruling Out Infection
- A standard echocardiogram (ultrasound of the heart) is the first test. It shows the leak and how big it is.
- A transesophageal echo (TEE) — a small probe passed into the throat — gives a much clearer view of a valve, especially the mitral valve. It is often the key test for PVL.
- 3D TEE maps the exact size, shape, and location of the gap. This is what the team uses to plan a closure.
- A CT scan can add detail and help plan the device and the catheter path.
- Blood tests look for anemia and signs of hemolysis (low hemoglobin, high LDH, low haptoglobin).
- Rule out infection. A new or growing leak always prompts blood cultures and a check for endocarditis, because infection can both cause a leak and be dangerous on its own.
Fixing It — Watch, Transcatheter Closure, or Surgery
- Watch: small leaks with no symptoms are followed with a yearly echo. No procedure is needed unless things change.
- Transcatheter closure (modern first choice): through a thin catheter, the team places a small plug — an occluder or vascular plug — into the gap to seal it. No chest opening.
- Named devices used to plug the gap include the Amplatzer Vascular Plug III and other purpose-built occluders selected to match the gap's shape.
- In PubMed-indexed multicenter series, closure had a device-success rate near 90% and improved symptoms or hemolysis in roughly 8 of 10 patients.
- Repeat surgery is chosen when there are several or very large gaps, when closure is not anatomically possible, or when the surgeon needs to fix something else at the same time.
- Treat infection first. If endocarditis caused the leak, antibiotics — and often surgery — come before any durable repair. The Heart Team makes the final call.
Points to Know
Shown in English for your safety — this section is not automatically translated. Confirm with your doctor or call the office.
If you remember nothing else, remember these key points.
- A paravalvular leak is a gap beside a replacement valve. Blood leaks around the valve, not through it.
- It can follow surgical valve replacement or TAVR. It is most common around mitral valves.
- Most leaks are small and only need watching with a yearly echocardiogram.
- A bigger leak causes two problems: heart failure (congestion) and hemolysis (anemia, dark urine).
- A new leak always prompts a check for infection (endocarditis).
- An echo — often a TEE (throat-probe echo) — finds and sizes the leak. CT can help plan a fix.
- A significant leak is usually fixed with a transcatheter closure (a plug) first; repeat surgery is the backup.
- Tell your dentist and doctors you have a replacement valve so you can be protected against infection.
