Your heart beats roughly 100,000 times a day, and each of those beats depends on four small but mighty valves opening and closing in perfect rhythm. For most of our lives, we never give them a second thought. But as we get older, these valves can stiffen, narrow, or start to leak — and because the changes happen gradually, many people don’t realise anything is wrong until symptoms become hard to ignore.
Heart valve disease is more common than you might think. According to the Irish Heart Foundation, it affects a significant number of people over 65, yet it remains underdiagnosed. The good news is that once identified, there are excellent treatment options — and catching it early makes all the difference.
TL;DR
- Heart valve disease becomes increasingly common after 50, particularly aortic stenosis and mitral regurgitation — yet it’s often missed in routine check-ups
- Key warning signs include breathlessness during everyday activities, unusual tiredness, dizziness, chest tightness, and swollen ankles
- A simple stethoscope check by your GP can detect a heart murmur; an echocardiogram confirms the diagnosis
- Treatment ranges from monitoring and medication to modern procedures like TAVI (transcatheter aortic valve implantation), which is available in Irish hospitals
- The HSE Chronic Disease Management Programme covers heart-related conditions — ask your GP about structured reviews
What Are Heart Valves and What Goes Wrong?
Your heart has four valves — the aortic, mitral, tricuspid, and pulmonary — that act as one-way doors, keeping blood flowing in the right direction. Two main things can go wrong:
- Stenosis — the valve narrows and doesn’t open fully, forcing your heart to work harder to push blood through
- Regurgitation (or incompetence) — the valve doesn’t close properly, allowing blood to leak backwards
The most common types in older adults are aortic stenosis (where the aortic valve stiffens and narrows, often due to calcium deposits building up over decades) and mitral regurgitation (where the mitral valve allows blood to leak back into the left atrium).
Both conditions develop slowly. You might not notice anything for years — until your heart can no longer compensate for the extra workload.
Recognising the Warning Signs
Heart valve disease is sometimes called a ‘silent’ condition because symptoms creep in so gradually that people put them down to ‘just getting older’. But these signs are worth paying attention to:
- Breathlessness during activities that used to be easy — walking uphill, climbing stairs, or carrying shopping
- Unusual tiredness or fatigue that doesn’t improve with rest
- Dizziness or light-headedness, particularly on standing or during exertion
- Chest tightness or discomfort during physical activity
- Swollen ankles or feet — a sign your heart may be struggling to pump efficiently
- Heart palpitations — feeling your heart racing, fluttering, or beating irregularly
If you notice any of these, don’t dismiss them. Mention them to your GP. A conversation now could save you a much more difficult conversation later.
How Is It Diagnosed?
Diagnosis often starts simply — with your GP listening to your heart with a stethoscope. A heart murmur (an unusual sound between heartbeats) is often the first clue that a valve isn’t working as it should.
If a murmur is detected, your GP will typically refer you for an echocardiogram — an ultrasound scan of the heart. This painless test shows your valves in real time, revealing how well they’re opening and closing and how your heart is coping overall.
In some cases, additional tests may include:
- ECG (electrocardiogram) — checks the electrical activity of your heart
- Chest X-ray — can show whether the heart has enlarged
- Cardiac MRI or CT scan — provides detailed images for surgical planning
Research from the Irish Longitudinal Study on Ageing (TILDA) has highlighted that cardiovascular conditions, including valve disease, are frequently underdetected in community-dwelling older adults in Ireland. This is why regular check-ups with your GP become increasingly important after 50.
Treatment Options: From Monitoring to Modern Procedures
Treatment depends on the type and severity of the valve problem, and how much it’s affecting your daily life.
Watchful Waiting
If the condition is mild and you have no symptoms, your cardiologist may recommend regular monitoring — typically an echocardiogram every one to two years — to track any changes. Many people live well for years with mild valve disease that never requires intervention.
Medication
While medication can’t fix a damaged valve, it can help manage symptoms and protect your heart. Your doctor may prescribe:
- Diuretics to reduce fluid build-up
- Blood pressure medications to ease the workload on your heart
- Blood thinners if you’re at risk of clots, particularly with atrial fibrillation
- Rate-controlling drugs for irregular heartbeat
Surgical Valve Repair or Replacement
For more severe disease, surgery may be needed. Options include:
- Valve repair — the surgeon fixes the existing valve, preserving your own tissue where possible
- Valve replacement — the damaged valve is replaced with a mechanical valve or a biological (tissue) valve
Open-heart valve surgery is well-established in Ireland, with excellent outcomes at centres including the Mater Misericordiae University Hospital in Dublin and University Hospital Galway.
TAVI: A Less Invasive Option
For older adults with severe aortic stenosis, TAVI (transcatheter aortic valve implantation) has been a game-changer. Rather than open-heart surgery, a new valve is delivered through a small incision in the leg and guided into place via a catheter. Recovery time is significantly shorter — many patients are home within a few days.
TAVI is now available at several Irish hospitals and is increasingly offered to patients who might previously have been considered too frail for traditional surgery. Your cardiologist and a multidisciplinary heart team will assess which approach is best for you.
Living Well with Heart Valve Disease
Whether you’re being monitored or have had treatment, there’s plenty you can do to support your heart health:
- Stay active — Regular moderate exercise (like walking, swimming, or gentle cycling) is beneficial for most people with valve disease. Your GP or cardiac rehabilitation team can advise on what’s safe for you. Ireland’s Local Sports Partnerships offer programmes specifically designed for people with heart conditions
- Eat well — A heart-healthy diet rich in fruit, vegetables, wholegrains, and oily fish supports cardiovascular function. The Irish Heart Foundation’s Happy Heart resources offer practical Irish-focused dietary advice
- Manage your weight and blood pressure — Both directly affect how hard your heart has to work
- Don’t smoke — If you smoke, the HSE QUIT service (Freephone 1800 201 203) provides free support
- Attend your appointments — Regular follow-up with your GP and cardiologist is essential. The HSE Chronic Disease Management (CDM) Programme provides structured GP reviews for people with cardiovascular conditions, at no extra charge for those with a medical card or GP visit card
- Know when to seek help — If your symptoms worsen suddenly — new breathlessness, fainting, or chest pain — seek medical attention promptly
Cardiac Rehabilitation in Ireland
If you’ve had valve surgery or TAVI, cardiac rehabilitation is one of the most important steps in your recovery. These supervised programmes — offered at hospitals across Ireland — combine structured exercise with education on diet, medication, and stress management.
The Irish Heart Foundation recommends that all cardiac patients attend rehabilitation. It’s been shown to improve fitness, reduce hospital readmissions, and boost confidence after a heart procedure. Ask your hospital team for a referral before you’re discharged.

A Word from Críonna Health
Heart valve disease is one of those conditions that rewards early detection. If you’re over 50, make sure your GP listens to your heart at your next visit — it takes just a few seconds with a stethoscope and could pick up something worth investigating. And if you’ve already been diagnosed, take heart (quite literally): treatments have never been better, and with the right support, most people continue to live full, active lives.
At Críonna Health, we believe that understanding your health is the first step to protecting it. You can explore more practical guides on healthy ageing at crionnahealth.reptile.haus.
