Minimally Invasive Cardiac Surgery (MICS): Patient Guide

Understand what “minimally invasive” means—and why the safest approach is individual.

What is MICS?

Minimally invasive cardiac surgery uses smaller access points or specialised instruments instead of a traditional full breastbone opening for selected operations. The exact incision and technique depend on the procedure and the patient’s anatomy.

Who may be suitable?

Suitability depends on the valve or structure being treated, CT and echo findings, previous surgery, body shape, lung function, kidney health and the surgeon’s assessment. Smaller incisions do not mean a smaller operation in terms of planning or follow-up.

Potential benefits and trade-offs

Some patients may experience a smaller scar or different recovery experience. There can also be technical limitations, conversion to another approach, and procedure-specific risks. The team should explain both benefits and alternatives.

Preparing for MICS

• Bring all imaging, especially CT or angiography discs when available.
• Ask whether physiotherapy, breathing exercises or prehabilitation would help.
• Plan transport, home support, medicines and wound-care supplies.

Recovery

Recovery includes monitoring, pain control, breathing exercises, walking and a gradual return to activity. Follow-up is important even when the external wound looks small.

FAQs

Is MICS suitable for everyone?

No. The safest approach may be conventional surgery for some patients.

Will I have no scar?

No. MICS uses smaller access incisions, but every operation leaves a scar that changes during healing.
