Keyhole Heart Surgery and the 2025 ESC Guidelines
Introduction
The European Society of Cardiology (ESC) and the European Association for Cardio-Thoracic Surgery (EACTS) have just released their 2025 guidelines on the management of heart valve disease. These updates are designed to ensure patients receive the very best, evidence-based care.
At The Keyhole Heart Clinic in London, it’s reassuring to see that the new recommendations mirror exactly the way we already care for our patients – through minimally invasive heart surgery, early treatment when appropriate, and multidisciplinary (MDT) decision-making.
For patients in the UK seeking alternatives to traditional open-heart surgery, the message is clear: the future is minimally invasive, and at our clinic, the future is already here.
Minimally Invasive Surgery: The Future is Already Here
One of the strongest themes of the new guidelines is the importance of minimally invasive and transcatheter procedures. Instead of opening the breastbone, these techniques use small incisions or catheter-based approaches to repair or replace heart valves.
Why this matters for patients:
- ✅ Faster recovery – most patients are back to normal life far sooner.
- ✅ Less pain – smaller incisions mean a much more comfortable healing process.
- ✅ Fewer complications – reduced infection risk and lower trauma to the body.
- ✅ Better outcomes – the heart is treated effectively without the impact of major surgery.
At The Keyhole Heart Clinic, we have specialised in these procedures for years. Our patients benefit from:
- Keyhole coronary bypass surgery (TCRAT) for double, triple or quadruple bypass.
- Keyhole mitral and aortic valve repairs/replacements.
- Integration of catheter-based techniques such as TAVI and TEER when suitable.
Aortic Valve Stenosis
What’s new in the guidelines?
Aortic Valve Stenosis
- Earlier treatment is advised: Even if you don’t feel symptoms, severe aortic stenosis may now be treated earlier to avoid sudden deterioration.
- TAVI (transcatheter valve replacement) is more widely available: Patients aged 70 or above may now be offered a keyhole valve replacement regardless of surgical risk.
- Heart Team review: Decisions should always be made by a team of experts in a dedicated valve centre.
What this means for you:
At our London clinic, we already combine advanced imaging, MDT review, and minimally invasive valve surgery wherever possible. This ensures that patients receive care that is not only up-to-date but ahead of the game.
Aortic Regurgitation (Leaking Aortic Valve)
Aortic regurgitation (AR) means the aortic valve does not close properly, so blood leaks backwards into the heart. Over time this can stretch and weaken the heart muscle.
When is surgery needed?
-
If you have symptoms such as breathlessness, fatigue, or swelling, surgery is usually recommended straight away.
-
Even without symptoms, surgery may be advised if the heart is becoming stretched (on an ultrasound scan) or the pumping function is starting to fall.
-
If you are already having heart surgery for another reason (such as a bypass or aortic aneurysm), a leaking valve will usually be fixed at the same time.
Repair or replacement?
In some patients the valve can be repaired rather than replaced – this avoids the need for a mechanical or tissue valve. But this is only possible in specialist centres with the right expertise.
What about keyhole or transcatheter options?
A TAVI (keyhole valve replacement) may be possible in certain patients who are too high-risk for open surgery. This depends on the shape of your valve and aorta and must be decided by a specialist “Heart Team.
[TKHC Comment: Generally though, TAVI is only possible if there is significant calcification to allow the TAVI valve to hold firmly.]
Bicuspid Aortic Valve (BAV)
Some people are born with a bicuspid valve (two flaps instead of three). This is common and often runs in families. It can cause either narrowing (stenosis), leaking (regurgitation), or enlargement of the aorta.
Treatment options:
-
In most patients who are otherwise fit, traditional surgery (sometimes through a minimally invasive approach) is still the best long-term option.
-
In selected older or higher-risk patients, a TAVI (keyhole replacement) may be considered if the valve anatomy is suitable.
-
Because bicuspid valves can be more complex, they should be managed in experienced centres that deal with large numbers of valve cases.
- Please also refer to the section on Aortic Root Aneurysm to understand treatment of bicuspid valve disease in aortic root disease.
Aortic Valve–Sparing Root Replacement (David Procedure)
Sometimes the problem is not the valve itself but the aortic root (the first part of the aorta) which becomes enlarged. This can make the valve leak.
What is valve-sparing root replacement?
-
In carefully chosen patients, surgeons can preserve your own valve and replace just the enlarged aorta.
-
This means you avoid an artificial valve and often do not need lifelong blood-thinning tablets.
-
This is most suitable for younger patients with healthy valve leaflets and is carried out in specialist centres with the right experience.
Why this matters:
Keeping your own valve can give more natural blood flow, better quality of life, and avoids some of the long-term complications of replacement valves.
Aortic Root Aneurysm
The aortic root is the section of the body’s main artery (the aorta) that sits right above the heart. In some people, this part of the aorta can stretch and enlarge — this is called an aortic root aneurysm. If it becomes too large, it can tear (dissection) or burst (rupture), which is life-threatening.
When is surgery needed?
-
Surgery is usually recommended if the root diameter becomes 5.5 cm or larger.
-
If you have a bicuspid valve, a genetic condition (like Marfan syndrome), or a family history of aortic problems, surgery is advised earlier – often when the root reaches 5.0 cm, or even 4.5 cm in high-risk situations.
-
If you need aortic valve surgery for another reason, and the root is already enlarged, both problems are often treated at the same time.
Types of surgery
-
Composite graft replacement (Bentall procedure): the aneurysm and the valve are replaced together with an artificial tube and valve.
-
Valve-sparing root replacement (David procedure): in selected patients with healthy valve leaflets, the aneurysm can be repaired while keeping your own valve (so you may avoid lifelong blood-thinning tablets).
Why early referral matters
Aortic root aneurysms often cause no symptoms until it’s too late. Regular scans, careful measurement, and early surgery in a specialist centre give the best chance of long-term survival and preserving quality of life.
Mitral Valve Regurgitation (Leak)
What’s new in the guidelines?
- Early surgery is now strongly recommended: Patients with severe mitral valve leakage should be offered repair before symptoms become severe.
- Newer catheter-based repairs are recognised: Techniques like TEER (transcatheter edge-to-edge repair) are proven safe and effective for those unsuitable for surgery.
What this means for you:
We’ve always believed in early repair for mitral valve disease – ideally through a keyhole mitral valve repair – to protect heart function and long-term health. Our MDT ensures your treatment plan is tailored to your personal circumstances and life goals.
Mitral Valve Stenosis (Narrowing of the Mitral Valve)
Mitral stenosis happens when the valve between the left atrium and left ventricle becomes narrowed, most often due to rheumatic heart disease (although this is now less common in the UK). The narrowed valve makes it harder for blood to flow forward, which can cause breathlessness, palpitations, swelling, or tiredness.
When is treatment needed?
-
If you have severe narrowing and symptoms, treatment is usually recommended.
-
Even if you don’t have obvious symptoms, intervention may be needed if the pressure in the lungs is high, or if you are at risk of blood clots or developing atrial fibrillation.
-
If you are planning a pregnancy, treatment may be advised earlier, as pregnancy puts extra strain on the heart.
Treatment options:
-
Balloon Valvotomy (Keyhole Stretching): If the valve is suitable (not too scarred or calcified), a catheter-based procedure called percutaneous mitral commissurotomy (PMC) can stretch the valve open. This avoids open-heart surgery.
-
Mitral Valve Surgery: If balloon treatment isn’t possible or has failed, surgery may be needed. Depending on the valve’s condition, this could mean a repair (keeping your own valve) or a replacement with a tissue or mechanical valve.
-
Medical treatment: Tablets such as diuretics, rate-control drugs, or blood thinners may help symptoms, but they do not fix the narrowed valve itself.
Key messages from the guidelines:
-
Always have your case reviewed by a specialist Heart Valve Centre so the right treatment can be chosen for you.
-
Where possible, balloon treatment is the first choice for suitable valves, as it is less invasive.
-
If surgery is needed, minimally invasive or keyhole approaches may be an option in expert centres.
Tricuspid Valve Disease
What’s new in the guidelines?
- Address the tricuspid valve early: If you’re already having surgery for another valve, the tricuspid valve should be fixed at the same time if it’s leaking.
- New minimally invasive options: High-risk patients with severe tricuspid regurgitation may now benefit from transcatheter repair or replacement.
What this means for you:
At The Keyhole Heart Clinic, we never ignore the tricuspid valve. During our MDT reviews, we routinely assess it and, where possible, repair it through keyhole techniques at the same time as other surgery – preventing the need for future operations.
Pulmonary Valve Disease (Less Common)
What’s new in the guidelines?
- Care for pulmonary valve conditions should take place in specialist centres with advanced imaging and expertise.
What this means for you:
Although pulmonary valve disease is rare, our clinic takes the same approach – no valve is overlooked. Every case is carefully reviewed by our MDT to ensure the most advanced, minimally invasive care possible.
The Bigger Picture
Across all valve types, the 2025 ESC guidelines highlight:
- Minimally invasive treatments wherever possible
- MDT (Heart Team) working in specialist centres
- Earlier treatment to protect the heart
- Patient-centred care, guided by your goals and values
This has been the foundation of our care at The Keyhole Heart Clinic from day one. It’s wonderful to see the global guidelines now confirm that this is the standard patients everywhere should expect.
Frequently Asked Questions (FAQs)
1. What is the difference between keyhole and open-heart surgery?
Keyhole (minimally invasive) surgery uses small incisions between the ribs instead of opening the breastbone. This means quicker recovery, less pain, and fewer complications compared to traditional open-heart surgery.
2. Am I eligible for minimally invasive heart surgery?
Most patients with valve disease or coronary artery disease are suitable for a minimally invasive approach, but eligibility depends on your specific condition. That’s why an MDT review is essential.
3. What is TAVI and who is it for?
TAVI (transcatheter aortic valve implantation) is a procedure where a new valve is implanted via a small tube, often through the groin. The 2025 guidelines now recommend TAVI for patients over 70 where appropriate.
4. How long does recovery take after keyhole heart surgery?
Most patients are home within days and return to normal activities within weeks – much faster than the typical 3 months after open-heart surgery.
5. Why does MDT (Heart Team) care matter?
An MDT ensures your treatment is planned by surgeons, cardiologists, imaging specialists, and anaesthetists together. This means all options are considered and your care is truly tailored to you.
