Rotablation is a medical procedure used to treat very hard or heavily calcified blockages in the heart’s arteries.
These blockages stop blood flowing properly and can lead to chest pain, breathlessness, or heart attacks. Rotablation helps by using a tiny drill with a diamond-coated tip to grind away the hard calcium inside the artery. This makes it easier for doctors to widen the artery with a stent and restore normal blood flow to the heart. It is usually done when standard treatments like balloon angioplasty do not work because the artery is too stiff or blocked with calcium.
Rotablation is often used in people with severe coronary artery disease where the artery walls have become hardened with calcium. As we age, or if we have risk factors like high cholesterol, diabetes, or high blood pressure, fatty deposits and calcium can build up in the arteries.
In some cases, the calcium becomes so solid that balloons and stents cannot get through. This is where rotablation is useful, as it clears a path so that other treatments can be carried out successfully. Without it, some people might not be able to have life-saving procedures to restore blood flow.
The procedure is carried out in a cardiac catheterisation laboratory by a specialist team. A thin tube called a catheter is inserted, usually through an artery in the wrist or groin, and guided to the heart. At the end of this catheter is the tiny drill, which spins at very high speed.
The tip of the drill is covered with microscopic diamond particles, which gently grind away the calcium in the artery. The tiny fragments are broken down into dust-like particles, which are washed away harmlessly in the bloodstream. Once enough calcium is removed, the artery can be widened with a balloon and a stent can be placed to keep it open.
The procedure itself is not painful, because local anaesthetic is used where the catheter is inserted. Patients are usually awake but given medicine to help them relax. Some people may feel pressure in the chest during the procedure, but pain is uncommon. Afterward, there may be mild bruising or soreness at the insertion site, but this usually improves within a few days.
The procedure usually takes between 30 minutes and 2 hours, depending on how many arteries are being treated and how complex the blockages are. Most patients stay in hospital overnight for monitoring, but some may go home the same day if everything is straightforward.
Rotablation is generally considered safe, but like all medical procedures it carries some risks. Possible complications include damage to the artery, irregular heart rhythms, or the artery closing up again. Serious complications are rare, especially when the procedure is performed by experienced cardiologists.
For many patients, the benefits of rotablation outweigh the risks, as it allows successful treatment in cases where other methods would fail.
The procedure is performed by an interventional cardiologist, a doctor who specialises in treating heart disease with minimally invasive techniques. They work with a team of nurses, radiographers, and technicians in the catheterisation lab. The team monitors the patient closely throughout the procedure, keeping track of heart rhythm, blood pressure, and oxygen levels.
After the procedure, patients are taken to a recovery area where they are monitored for a few hours. Most people are advised to lie flat for a short time if the catheter was inserted through the groin. If it was done through the wrist, recovery is often quicker.
Patients usually go home within one or two days and are advised to avoid heavy lifting or strenuous exercise for about a week. Medicines such as blood thinners are often prescribed to prevent clots from forming around the stent.
Follow-up appointments with a cardiologist are arranged to check progress and ensure the artery is healing well.
The main benefit is that it makes it possible to treat heavily calcified blockages that would otherwise be very difficult or impossible to fix. By clearing a pathway through the calcium, rotablation allows stents to be placed securely. This improves blood flow to the heart, relieves chest pain, and reduces the risk of heart attack.
For many patients, this means a better quality of life, with fewer symptoms and more energy for everyday activities.
In some cases, other treatments may be considered. Standard balloon angioplasty and stenting are often used first, but they may not work if the artery is too hard. In rare cases, bypass surgery may be an alternative, but this is a more invasive operation.
Another newer technique called orbital atherectomy works in a similar way to rotablation, using a different type of spinning device to remove calcium. However, rotablation remains one of the most widely used and proven methods.
Rotablation does not cure the underlying cause of heart disease. It clears blockages to improve blood flow, but the build-up of fatty deposits and calcium can continue if risk factors are not controlled.
This is why lifestyle changes and medicines remain important after the procedure. Eating a healthy diet, exercising regularly, stopping smoking, and taking prescribed medicines such as statins or blood pressure tablets all help protect the arteries from further damage.
Most people feel an improvement in symptoms such as chest pain or shortness of breath soon after the procedure. Recovery is usually quicker than with open-heart surgery, and many patients return to normal activities within a week or two.
Long-term outcomes depend on overall health and lifestyle choices. With proper care, many people go on to live active and fulfilling lives after rotablation. Regular check-ups with a cardiologist are important to monitor heart health and prevent further problems.
In the UK, rotablation is available on the NHS for patients who need it. It is usually offered when other treatments are not suitable. Waiting times can vary depending on the hospital and region.
Private treatment may be faster and can sometimes offer more choice of hospital or specialist, but the procedure and outcomes are essentially the same. The decision often depends on personal preference, cost, and urgency.
Rotablation is a procedure used to treat hard, calcified blockages in the arteries of the heart. It works by using a tiny diamond-tipped drill to clear calcium, making it easier to place stents and restore blood flow. The procedure is safe and effective, with most patients noticing quick improvements in symptoms like chest pain and breathlessness.
Although rotablation does not cure heart disease, it plays an important role in helping people manage the condition and avoid more invasive surgery. With follow-up care, lifestyle changes, and ongoing medical support, many people live long and active lives after the procedure.
