For decades, heart surgery meant a long incision down the centre of the chest and dividing the breastbone. That approach, known as a median sternotomy, is still the standard for many operations and works very well. But for selected patients, surgeons can now reach the heart through much smaller incisions, and the difference in recovery can be substantial.
What is minimally invasive cardiac surgery?
Minimally invasive cardiac surgery, often shortened to MICS, describes heart operations performed through small incisions, usually between the ribs, rather than by opening the breastbone.
Surgeons use specialised long instruments and a camera inserted into the chest to see the heart on a screen. Some centres also use robotic assistance for parts of the procedure. In many MICS operations, the heart-lung machine is still used, connected through small vessels.
It is not the same as a catheter procedure such as angioplasty or TAVI, which work from inside the blood vessels. MICS is still surgery, just through a smaller doorway.
Which conditions can it treat?
Common uses include mitral valve repair or replacement, some aortic valve operations, repairing an atrial septal defect, an opening or hole in the wall separating the heart’s two upper chambers, removal of certain heart tumours and coronary bypass for one or two blocked arteries.
Who is a suitable candidate?
Suitability depends on the condition and the person. Factors include the type and complexity of the heart problem, the number of arteries or valves involved, lung function, body shape, previous chest surgery and overall health.
Patients with complex disease affecting several valves or many arteries are often better served by conventional surgery. Age alone is not usually a barrier. Before deciding, surgeons typically review an echocardiogram, CT scan, ECG, blood tests and sometimes cardiac MRI.
What are the potential benefits?
For patients, the most noticeable difference is usually in the first weeks after the operation. Studies of suitable patients report less pain, less blood loss, a lower risk of wound and breastbone complications, shorter hospital stays and a faster return to everyday activities. The scars are smaller and easier to conceal. Importantly, for well-selected patients, the quality of the repair is designed to match that of open surgery.
What are the risks?
Like any heart operation, MICS carries risks, including bleeding, infection, irregular heart rhythm, stroke and complications of anaesthesia. Occasionally surgeons need to convert to a conventional open approach during the operation for safety. MICS also tends to take longer to perform and requires specific training and equipment.
How does recovery compare?
After open-heart surgery, most patients stay in hospital for around a week. The breastbone usually needs six to eight weeks to heal. Recovery after minimally invasive cardiac surgery (MICS) is often quicker, with many patients going home within a few days. However, driving, heavy lifting and strenuous exercise may still be restricted for several weeks. Cardiac rehabilitation helps patients regain strength after either procedure.
Robotic assistance, explained
In robotic-assisted surgery, the surgeon operates from a console and controls instruments mounted on robotic arms, viewing a magnified three-dimensional image of the heart. The robot does not operate on its own; it translates the surgeon’s hand movements into precise movements inside the chest. It can help in tight or deep spaces. Whether it is used depends on the operation and the team’s experience, and good results can be achieved with or without it.
Questions to ask
Am I a candidate for a minimally invasive approach, and why? How often does your team perform this specific operation? What happens if you need to convert to open surgery? What will my recovery look like week by week?
Where is minimally invasive heart surgery available in Dubai?
Aster Hospitals, which runs hospitals across Dubai including Aster Cedars Hospital & Clinic in Jebel Ali and sites in Al Qusais, Mankhool and Muhaisnah, describes its minimally invasive cardiac surgery in Dubai service as using thoracoscopic, robotic-assisted or port-access techniques depending on the case.
Procedures include valve repair and replacement, coronary bypass, atrial septal defect closure and tumour removal. The group reports typical hospital stays of three to five days, with follow-up at one week, one month and three months.
Minimally invasive heart surgery can mean less pain, smaller scars and a shorter recovery for suitable patients. However, the best approach depends on the heart condition, the complexity of the operation and the surgeon’s experience.
Patients weighing up the best cardiology hospital in Dubai for valve or bypass surgery should ask whether both minimally invasive and conventional approaches are available, so they can make their choice on clinical grounds alone.
