If you or a loved one has been advised to undergo heart surgery, it’s natural to have questions. Most people immediately think of open-heart surgery, which typically involves a long and demanding recovery. However, in many cases, a minimally invasive heart surgery (MIHS) may be a suitable and effective alternative.
What Is Minimally Invasive Heart Surgery?
Minimally invasive heart surgery is a modern, advanced technique used to treat various heart conditions without the need to open the chest by cutting through the breastbone. Instead, the procedure is performed through a small 4–6 cm incision made on the side of the chest, usually just below the nipple. Surgeons access the heart by carefully going between the ribs, without cutting any bones.
This approach makes the procedure especially suitable for older patients and those with diabetes, who may have a higher risk of infection and slower recovery times with traditional surgery.
Conditions It Can Treat
Minimally invasive heart surgery is used for a range of cardiac procedures, including:
Coronary artery bypass graft (CABG) – Restores blood flow to the heart by bypassing blocked arteries
Valve surgeries – Repair or replacement of mitral, tricuspid, or aortic valves
Aneurysm repair – Treats bulges or weaknesses in blood vessel walls
Closure of congenital defects – Including atrial septal defect (ASD), patent foramen ovale (PFO), and atrioventricular septal defects
Who Is a Candidate?
Not everyone is eligible for minimally invasive surgery. Whether you’re a suitable candidate depends on several factors, such as:
Your overall health and medical history
The type and severity of your heart condition
Diagnostic test results
Your doctor will perform a physical examination, review your medical records, and possibly order additional tests. Based on this evaluation, your healthcare provider will determine if MIHS is the right option for you. In any case, it is recommended to have the surgery at a specialized centre with experienced surgeons trained in these procedures.
Preparing for the Surgery
Your doctor will provide detailed instructions before your surgery, including:
What to expect before, during, and after the procedure
Potential risks and complications
Preoperative steps like shaving hair at the surgical site
Guidelines for planning your post-hospital care at home
You may be encouraged to have discussions with family members about the recovery period and any assistance you might need once you're discharged.
Benefits of Minimally Invasive Heart Surgery
No splitting of the breastbone (sternum)
Reduced pain and faster recovery
Minimal blood loss, often eliminating the need for transfusions
Lower risk of infections and bleeding
Shorter ICU and hospital stay
Improved lung function after surgery
Smaller, less visible scars
Improved overall quality of life
Most importantly, all heart blockages—regardless of location—can typically be bypassed safely and predictably using this technique.
Minimally invasive heart surgery is transforming the way cardiac care is delivered. If you or your loved one is facing heart surgery, be sure to discuss all available options with your cardiologist or cardiac surgeon. The right choice could lead to a smoother recovery and better long-term outcomes.
