Minimally Invasive Techniques for Heart Surgery
What is Minimally Invasive Surgery?
Minimally invasive surgery (MIS) refers to surgical procedures that use small incisions, specialised instruments, and advanced technology to minimise tissue damage and promote faster recovery. The goal of MIS is to reduce the trauma and stress associated with traditional open surgery.

Characteristics of Minimally Invasive Surgery
- Small incisions: MIS uses small incisions, often 0.5-2 cm long, to access the affected area.
- Specialised instruments: Surgeons use specialised instruments, such as laparoscopic or endoscopic tools, to perform the procedure.
- Advanced technology: MIS often employs advanced technology, including cameras, lights, and robotic systems, to enhance visualisation and precision.
- Reduced tissue damage: MIS aims to minimise tissue damage, which can lead to less post-operative pain, reduced risk of complications, and faster recovery.
Types of Minimally Invasive Surgery
- Laparoscopic surgery: MIS uses a laparoscope (a thin, lighted tube with a camera) to visualise the internal organs through small incisions.
- Endoscopic surgery: MIS uses an endoscope (a thin, flexible tube with a camera and light) to visualise the internal organs through small incisions.
- Robotic-assisted surgery: MIS uses robotic systems to assist the surgeon during the procedure.
- Natural orifice transluminal endoscopic surgery (NOTES): It uses natural orifices (such as the mouth or vagina) to access the internal organs.
Benefits of Minimally Invasive Surgery
- Less post-operative pain: Reduced tissue damage leads to less pain after surgery.
- Faster recovery: Patients can often return to normal activities within a few days or weeks.
- Reduced risk of complications: MIS can reduce the risk of complications, such as infection and bleeding.
- Improved cosmetics: Small incisions result in less scarring.
Limitations and Risks of Minimally Invasive Surgery
- Not suitable for all patients: MIS may not be perfect for patients with complex conditions or emergency surgery.
- Steep learning curve: Surgeons require specialised training and experience to perform MIS procedures.
- Equipment costs: The cost of specialised equipment and technology can be high.
- Risk of conversion to open surgery: In some cases, the surgeon may need to convert the procedure to open surgery, which can increase the risk of complications.
What is minimally invasive heart surgery used for?
Surgeons use Minimally Invasive Heart Surgery (MIHS) to treat a variety of heart conditions, including:
Structural Heart Diseases
- Mitral valve repair/replacement: Surgeons use MIHS to repair or replace the mitral valve, which regulates blood flow between the heart's chambers.
- Aortic valve replacement: Experts use MIHS to replace the aortic valve, which regulates blood flow from the heart to the rest of the body.
- Tricuspid valve repair/replacement: Drs use MIHS to repair or replace the tricuspid valve, which regulates blood flow between the heart's chambers.

| Minimally Invasive Cardiac Surgery |
- Coronary artery bypass grafting (CABG): Surgeons use MIHS to bypass blocked coronary arteries, restoring blood flow to the heart.
- Coronary artery disease treatment: Cardiologists use MIHS to treat coronary artery disease by removing blockages or performing angioplasty.
Heart Rhythm Disorders
- Atrial fibrillation treatment: MIHS can be used to treat atrial fibrillation, a type of irregular heartbeat.
- Maze procedure: MIHS can be used to perform the maze procedure, which treats atrial fibrillation by creating a pattern of scar tissue in the heart.
Other Heart Conditions
- Heart defect repair: Experts use MIHS to repair heart defects, such as atrial septal defects (ASDs) or ventricular septal defects (VSDs).
- Cardiac tumour removal: Surgeons remove cardiac tumours using MIHS.
Benefits of Minimally Invasive Heart Surgery
- Less post-operative pain: Reduced tissue damage leads to less pain after surgery.
- Faster recovery: Patients can often return to normal activities within a few weeks.
- Reduced risk of complications: MIHS can reduce the risk of complications, such as infection and bleeding.
- Improved cosmetics: Small incisions result in less scarring.
How do cardiac surgeons carry out minimally invasive heart surgery?
Cardiac surgeons carry out minimally invasive heart surgery by making small incisions, using specialised instruments, and employing advanced technologies like robotic-assisted systems and 3D imaging.
Surgeons Perform Minimally Invasive Heart Surgery by:
- Making small incisions in the chest.
- Inserting a thoracoscope or endoscope to visualise the heart.
- Using specialised instruments to repair or replace damaged heart structures.
- Navigate the tools through your ribs to access your heart.
- Utilising robotic-assisted systems or 3D imaging to enhance precision.
- Closing the incisions, often with minimal scarring.
What happens after minimally invasive heart surgery?
After minimally invasive heart surgery, here's what typically happens:
- Recovery in the ICU: Doctors and their team closely monitor the Intensive Care Unit (ICU) for several hours or overnight.
- Pain management: Patients receive pain medication to manage discomfort and pain.
- Breathing support: Patients may require oxygen therapy or temporary ventilation support.
- Monitoring: Medical teams closely monitor vital signs, wound sites, and overall health.
- Gradual mobilisation: Patients are encouraged to move around, sit, and walk to prevent complications.
- Follow-up care: Patients receive guidance on wound care, medication, and follow-up appointments.
- Rehabilitation: Patients may undergo cardiac rehabilitation to regain strength, endurance, and overall health.
Individual recovery experiences may vary depending on the patient's condition, surgery type, and overall health.

What benefits does minimally invasive heart surgery offer?
Minimally Invasive Heart Surgery offers numerous advantages:
Reduced Trauma
- Smaller incisions: Less tissue damage and scarring.
- Less pain: Reduced post-operative pain and discomfort.
Faster Recovery
- Shorter hospital stay: Typically 3-5 days, compared to 7-10 days for open-heart surgery.
- Quicker return to normal activities: Patients can often resume daily activities within 2-4 weeks.
Minimised Risks
- Reduced infection risk: Smaller incisions minimise the chance of infection.
- Less bleeding: Reduced risk of bleeding complications.
- Fewer complications: Lower risk of respiratory, renal, or neurological complications.
Improved Outcomes
- Better cosmetic results: Smaller scars and less tissue damage.
- Reduced risk of adhesions: Minimally invasive approaches reduce the risk of adhesions.
- Improved quality of life: Patients often experience improved overall health and well-being.
When should I see my doctor after minimally invasive heart surgery?
It's essential to follow your doctor's instructions for post-operative care. Here are some general guidelines:
Immediate Follow-up
- 1-2 weeks after surgery: Schedule a follow-up appointment with your doctor to:
- Remove stitches or staples
- Check the wound site
- Monitor for potential complications
- 2-4 weeks after surgery: Attend a follow-up appointment to:
- Assess your overall recovery
- Discuss any concerns or questions
- Receive guidance on returning to normal activities
Ongoing Care
- Regular check-ups: Schedule regular appointments with your doctor to:
- Monitor your heart health
- Adjust medications as needed
- Address any concerns or issues
- Cardiac rehabilitation: Participate in a cardiac rehabilitation program to:
- Improve cardiovascular health
- Enhance overall well-being
- Reduce the risk of future heart problems
Seek Immediate Medical Attention
- Chest pain or discomfort: If you experience severe chest pain, shortness of breath, or discomfort.
- Bleeding or swelling: If you notice unusual bleeding, swelling, or redness around the wound site.
- Fever or chills: If you develop a fever, chills, or other signs of infection.
- Difficulty breathing: If you experience shortness of breath, wheezing, or coughing.
Remember, it's always better to err on the side of caution. If you have any doubts about your recovery, contact your doctor immediately.
Minimally invasive heart surgery is a groundbreaking approach that offers numerous benefits, including reduced trauma, faster recovery, minimised risks, and improved outcomes. Patients can make informed decisions about their heart health by understanding the procedure, advantages, and post-operative care.
If you or a loved one is considering minimally invasive heart surgery, remember to:
- Consult with a qualified healthcare professional
- Discuss potential risks and benefits
- Follow post-operative care instructions carefully
- Attend scheduled follow-up appointments
By taking these steps, you can ensure a successful and smooth recovery from minimally invasive heart surgery.
