Robotic Heart Surgery: How Does It Work and Who Can Benefit?

Robotic heart surgery is a type of minimally invasive heart surgery. It uses small incisions instead of one large incision in the chest. During the procedure, the surgeon controls specialised robotic instruments from a nearby console. A small camera provides a clear, magnified view of the heart and the surgical area.

The robot does not perform the surgery on its own. The surgeon controls the robotic instruments and their movements throughout the procedure. This approach may help reduce blood loss, pain and scarring in suitable patients.

What Is Robotic Heart Surgery and How Does It Work?

Robotic heart surgery, also called robot-assisted heart surgery, is performed through small incisions between the ribs. The surgeon makes a few small incisions to insert a camera and specialised surgical instruments.

The camera provides a 3D view of the surgical area and can magnify the heart and nearby structures. The surgeon then controls the instruments using hand movements at a console.

The robotic system translates these movements into precise movements inside the chest. It also allows the surgeon to move the instruments in ways that may be difficult with traditional surgical tools. The surgeon remains in complete control throughout the procedure.

Before surgery, your heart team will review your medical history and test results. Tests such as an echocardiogram, CT scan or cardiac catheterisation may be needed. These tests help determine whether robotic heart surgery is suitable for you.

Which Heart Conditions Can Be Treated With Robotic Surgery? 

Robotic cardiac surgery can be used for selected heart conditions. It is not suitable for every patient or every type of heart surgery.

Depending on your condition, robotic surgery may be used for:

• Mitral valve repair or replacement
• Certain tricuspid valve procedures
• Selected coronary artery bypass procedures
• Repair of some congenital heart defects
• Removal of certain benign heart tumours
• Other selected heart procedures

The type of surgery depends on your heart condition, its severity and your overall health. Your surgeon will assess whether a robotic approach is safe and suitable for you.

What Are the Benefits of Robotic Heart Surgery?

One of the main benefits of robotic surgery is that it allows surgeons to perform certain heart procedures through smaller incisions.

For suitable patients, possible benefits may include:

• Smaller incisions and scars
• Less pain after surgery
• Less blood loss
• Lower risk of infection at the surgical site
• Shorter hospital stay
• Faster recovery
• Earlier return to daily activities

Robotic surgery may also provide the surgeon with a magnified, 3D view of the heart and surrounding structures. The specialised instruments allow the surgeon to make small and precise movements during the procedure.

However, the benefits can vary from one person to another. Robotic heart surgery is still a major surgical procedure and carries risks. Your doctor can explain the potential benefits and risks based on your condition and the type of surgery being considered.

Robotic Heart Surgery vs Open-Heart Surgery: What Is the Difference?

The main difference is how the surgeon accesses the heart.

In traditional open-heart surgery, the surgeon may make a larger incision in the chest. In many procedures, the breastbone (sternum) is also divided to access the heart.

Robotic heart surgery uses smaller incisions, often between the ribs. A camera and specialised surgical instruments are inserted through these incisions. The surgeon controls the instruments from a console.

This does not mean robotic surgery is always better or safer. Some heart conditions require traditional surgery. Your surgeon will choose the approach based on your medical needs.

Who Is a Candidate for Robotic Heart Surgery?

Not everyone who needs heart surgery can have a robotic procedure. You may be considered for robotic surgery if:

• Your heart condition can be treated safely through a minimally invasive approach.
• Your overall health allows you to undergo surgery.
• Your heart anatomy is suitable for the procedure.
• Your surgeon has the required experience with robotic surgery.

Your doctor may recommend additional tests before making this decision. These tests help the heart team assess your heart's structure and function.

The final decision is made after considering your condition, medical history, test results and the type of surgery you need.

What Can Patients Expect During Recovery After Robotic Heart Surgery?

Recovery after robotic heart surgery may be shorter than recovery after some traditional open-heart procedures. However, recovery time varies depending on the type of procedure and your overall health.

After surgery, you will first be monitored in the hospital. Your medical team will check your heart rate, blood pressure, breathing and overall recovery.

You may have some pain or discomfort around the small incisions. Your doctor can prescribe medicines to help manage it.

As you recover, you will gradually start walking and doing light activities. Your doctor will tell you when you can safely increase your activity level.

Many people can return to normal activities within a few weeks. However, more complex procedures may require more time.

Follow your doctor's instructions about exercise, driving, lifting heavy objects and returning to work. Do not increase your activity too quickly, even if you start feeling better.

Final Thoughts

Robotic heart surgery offers a minimally invasive option for selected heart conditions and procedures. It uses smaller incisions and specialised instruments while the surgeon remains in control throughout the procedure. For suitable patients, it may offer benefits such as less pain, smaller scars and faster recovery. If you need heart surgery, talk to your heart specialist about whether a robotic approach is suitable for your condition.
