If your cardiologist has recommended heart surgery for your condition, you might be wondering: Should I choose robotic heart surgery or open-heart surgery? The best approach depends on your heart condition, the procedure you need, your overall health, and whether you are an eligible candidate for a minimally invasive approach.
Robotic heart surgery vs. open heart surgery is not simply a choice between “new” and “traditional” surgery. Robotic heart surgery is heart surgery done through very small cuts (incisions) in the chest and surgeon-controlled robotic instruments. On the contrary, open-heart surgery usually involves opening the chest through the breastbone to provide direct access to the heart.
Compared with traditional surgery, the benefits of robotic heart surgery may include smaller incisions with minimal scarring, less pain, less bleeding, and decreased risk of infection for appropriately selected individuals. However, open-heart surgery is still an important and highly effective approach for many complex heart conditions.
Hence, the best option between robot-assisted cardiac surgery and open-heart surgery is the one that allows your cardiac surgeon to treat your heart problem safely and effectively.
Quick Overview: Robotic Heart Surgery vs. Open-Heart Surgery
The biggest difference is how the surgeon reaches your heart.
In robot-assisted cardiac surgery, the surgeon makes several small incisions between the ribs. A camera gives a magnified, 3D view of the surgical area. Also, the specialised instruments attached to robotic arms are controlled by the surgeon from a console.
In open-heart surgery (sometimes called traditional heart surgery), the surgeon generally makes a larger incision in the chest and opens the breastbone, called the sternum, to access the heart directly.
Here is a quick snapshot of the difference between these two approaches:
| Feature | Robotic Heart Surgery | Open-Heart Surgery |
| Surgical access | Small incisions between the ribs. | Larger chest incision, usually via the breastbone. |
| Surgeon control | The surgeon controls robotic instruments. | The surgeon operates directly. |
| Scarring | Generally smaller scars. | Generally a larger chest scar. |
| Breastbone | Usually not divided. | Usually divided. |
| Pain | Maybe less after surgery. | Maybe more due to the larger incision and breastbone healing. |
| Hospital stay | Often shorter in suitable individuals. | Usually longer. |
| Recovery | Often faster. | Usually takes longer. |
| Suitable for | Selected heart procedures and patients. | Many complex and extensive heart procedures. |
Note: A robot does not perform the surgery independently. The cardiac surgeon controls every movement of the robotic instruments.
What Is Robotic Heart Surgery?
Robotic heart surgery (or robot-assisted cardiac surgery) is a type of minimally invasive heart surgery. During the surgery, a surgeon controls surgical tools attached to thin robotic arms. The surgeon does not open your chest in the way they do for traditional open heart surgery.
A tiny camera provides a highly magnified view of the surgical area. The surgeon then controls specialised instruments from a nearby console. These instruments can offer a wide range of movement and precise control in areas that can be difficult to reach through small openings.
Robotic cardiac surgery may be considered for procedures such as:
- Mitral valve repair.
- Mitral valve replacement.
- Septal myectomy.
- Removal of cardiac tumours (myxoma, fibroelastoma of the mitral or tricuspid valve).
- Coronary artery bypass graft (CABG).
- Tricuspid valve repair (with mitral valve repair).
- Atrial septal defect (ASD) repair.
- Patent foramen ovale (PFO) repair.
Benefits of Robotic Heart Surgery
The advantages for eligible candidates are:
- Smaller incisions
- Minimal scarring.
- Less pain.
- A shorter hospital stay (usually 3 to 4 days).
- Lower use of pain medications.
- Less bleeding and risk of infection.
- Fewer complications.
- A shorter recovery and quicker return to daily and professional activities.
However, not every heart surgery can be performed robotically. Your surgeon will assess your condition and determine your eligibility for the procedure.
Risks of Robotic Heart Surgery
Although robotic surgery uses smaller incisions, it does not eliminate the risks linked to heart surgery.
Possible risks include:
- Bleeding
- Infection
- Abnormal heart rhythms
- Stroke
- Heart attack
- Blood clots
- Complications related to anaesthesia
- Damage to nearby structures
- Need for additional surgery
- Conversion to open-heart surgery
The risk may vary depending on the specific procedure and the individual’s health. Your healthcare provider will discuss your risks before surgery. Ask questions to make sure you understand all of the potential risks.
Who Is a Candidate for Robotic Heart Surgery?
Not everyone is an eligible candidate for robot-assisted cardiac surgery.
Your cardiac surgeon may consider factors such as:
- The type of heart condition
- Severity and location of the disease
- Previous heart or chest surgeries
- Overall health
- Lung function
- Heart function
- Body structure and anatomy
- Results of imaging and other diagnostic tests
- The complexity of the required procedure
Tests may include an echocardiogram, cardiac catheterisation, CT scan, chest X-ray and other investigations.
Your surgeon will use these results to determine whether robotic, minimally invasive or open-heart surgery is most appropriate.
What Is Open-Heart Surgery?
Open-heart surgery is a type of traditional heart surgery that involves opening your chest wall so a surgeon can reach your heart more easily. With the help of this approach, the surgeons can reach your heart directly and treat the heart issue you have.
The surgeon may make an incision down the middle of the chest and divide the breastbone (sternum) to access the heart. Depending on the procedure, a heart-lung bypass machine may temporarily take over the functions of the heart and lungs.
Open-heart surgery may be used for:
- Coronary artery bypass grafting (CABG)
- Heart valve repair or replacement
- Heart transplantation
- Aneurysm repair
- Certain congenital heart defect repairs
- Placement of some mechanical heart-support devices
- Other complex heart procedures
Benefits of Open-Heart Surgery
Open-heart surgery offers life-saving benefits, including restored blood flow, enhanced life expectancy, and a significantly improved quality of life.
Risks of Open-Heart Surgery
Open-heart surgery risks include:
- Allergic reaction to anaesthesia
- Irregular heartbeat
- Bleeding
- Damage to surrounding blood vessels or organs like the lungs or kidneys
- Infections
- Blood clots
- Stroke
Robotic Heart Surgery vs Open-Heart Surgery: Which Has a Faster Recovery?
Recovery is usually shorter after minimally invasive procedures compared to conventional open-heart surgery, but it can vary significantly between individuals.
With robot-assisted cardiac surgery, smaller incisions and avoidance of breastbone division may allow some appropriately selected people to return to normal activities sooner.
Open-heart surgery requires the breastbone to heal, which can make recovery longer. In fact, many people require several weeks before they can comfortably resume normal activities. Complete recovery may take several months based on the type of operation and their overall health.
FAQs About Robotic Heart Surgery & Open-Heart Surgery
Is robotic heart surgery better or safer than open-heart surgery?
Not necessarily.
The right choice depends entirely on your specific condition, your heart’s anatomy, and the complexity of the procedure.
Is robotic heart surgery less painful?
Yes.
Unlike open-heart surgery, eligible patients undergoing robotic surgery may experience less postoperative pain because it generally uses smaller incisions and avoids dividing the breastbone.
Is open-heart surgery still performed today?
Yes.
Open-heart surgery is still an important treatment option for many conditions such as coronary artery disease, heart valve disease, certain congenital heart conditions, aneurysms and heart failure requiring specific surgical treatments.
How do I know which heart surgery is right for me?
Cardiac surgeons will only recommend the best approach that can offer you the best balance of safety and effectiveness for your situation. They will assess your diagnosis, anatomy, medical history, overall health and the complexity of the required procedure before making the final decision.
Conclusion
It is not accurate to say that robotic heart surgery is always safer or better than open-heart surgery because both of them have their own advantages.
Robotic heart surgery may provide benefits like smaller incisions, less scarring and a potentially faster recovery for carefully selected individuals. Open-heart surgery offers wider access to the heart and remains an important option for many complex procedures.
So, instead of asking only, “Which surgery is better?”, ask:
“Which surgical approach is best for my heart condition?”
Discuss these questions with your cardiac surgeon:
- Can my procedure be performed robotically?
- Am I a suitable candidate for minimally invasive heart surgery?
- What are the advantages and limitations of robotic surgery in my case?
- What are the risks of choosing robotic surgery?
- Would open-heart surgery provide better access for my condition?
- How long might I stay in the hospital?
- How long could my recovery take?
- How experienced is the surgical team with the procedure I need?
- What happens if robotic surgery needs to be converted to open surgery?
Understand your condition and make an informed decision with your cardiac team to know what is safe and best for you.
