Ask most people what an interventional cardiologist does, and they will say “puts in stents”. That is true, but it is only part of the picture. Over the past two decades, catheter-based techniques have taken on work that once required open-heart surgery, and the speciality now covers a surprisingly wide range of conditions.
What is Interventional Cardiology?
Interventional cardiology treats the heart from the inside, using thin tubes called catheters passed through a blood vessel, usually in the wrist or groin. X-ray imaging guides the catheter to the heart. Because the chest is not opened, recovery is usually measured in days rather than weeks. The trade-off is that not every problem can be solved this way, and choosing the right patients is a large part of the specialist’s skill.
Coronary Procedures
A large part of this work involves treating blocked or narrowed coronary arteries. Coronary angiography is used to find the location and extent of the blockage. Angioplasty and stenting can then improve blood flow, either as planned treatment for angina or as urgent treatment during a heart attack. More complex cases may require specialised procedures. CTO treatment is used to reopen arteries that have been completely blocked for a long period, while atherectomy helps treat heavily calcified arteries by removing hard plaque with a small rotating device. This can make it easier to place and fully expand a stent.
Structural Heart Procedures
This is the fastest-growing part of the field. Transcatheter aortic valve implantation, known as TAVI or TAVR, replaces a narrowed aortic valve without open surgery and is now a standard option for many older patients. Balloon valvuloplasty stretches open certain narrowed valves. Some holes in the heart, present from birth, can be closed with a small device delivered by catheter. These procedures usually involve a joint decision between cardiologists and cardiac surgeons, often called a heart team.
Rhythm Devices
Many interventional cardiologists and electrophysiologists (heart rhythm specialists) also implant devices.
- A pacemaker treats a heartbeat that is too slow.
- An implantable cardioverter-defibrillator (ICD) protects against dangerous fast rhythms.
- Cardiac resynchronisation therapy (CRT) helps the heart pump more efficiently in some patients with heart failure.
- Electrophysiology studies and catheter ablation can cure some fast rhythms altogether.
Beyond the Heart
Some interventional cardiologists also treat arteries elsewhere in the body. Peripheral artery disease, where narrowed arteries reduce blood flow to the legs, can cause pain on walking and slow-healing wounds, and is especially common in people with diabetes. Balloon and stent techniques similar to those used in the heart can often restore blood flow without open surgery.
There is No Single Right Procedure
Patients often search for the best interventional heart treatment in Dubai as if one option were always superior. In reality, the right procedure depends on the anatomy, the symptoms and the person. Someone with a single narrowed artery may do well with a stent; someone with widespread disease and diabetes may do better with bypass surgery; someone with stable symptoms may need neither and simply better medicines. A good interventional cardiologist will tell you when not to intervene.
How do You Choose an Interventional Cardiologist?
Credentials matter, but so does fit. The best cardiologist in Dubai for one patient may be the wrong choice for another. A few practical checks help:
Match the subspecialty to the problem. Coronary work, structural valve work and rhythm devices are different skill sets. Ask which procedures the doctor performs regularly.
Check the licence. Doctors practising in Dubai are licensed by the Dubai Health Authority, and their speciality should appear on that licence.
Ask about volume and outcomes. It is reasonable to ask how often a doctor performs a particular procedure and what complication rates look like.
Look at the back-up. Complex procedures are safer where cardiac surgery, intensive care and imaging are available in the same hospital.
Notice how they communicate. You should leave the consultation understanding the options, including the option of doing nothing yet. A second opinion is sensible for any major planned procedure.
Where is Interventional Cardiology Offered in Dubai?
Aster Hospitals is one Dubai hospital group offering it, with cardiologists practising at its hospitals in Mankhool, Al Qusais and Muhaisnah and at Aster Cedars Hospital, Jebel Ali. The published procedure list includes coronary angiography and angioplasty with stenting in a cardiac catheterisation lab, CTO interventions, atherectomy, balloon valvuloplasty for selected valve disorders, pacemaker, ICD and CRT implantation, and TAVI.
An online cardiologist directory lists each doctor’s subspecialty and hospital. The right specialist is not the one with the most impressive title. It is the one whose everyday work matches your specific heart problem.
