What is Minimally Invasive Heart Surgery / MICS ?

Minimally Invasive Cardiac Surgery or Heart Surgery is an emerging technique in which heart surgeries are performed through a small incision through the chest wall instead of the traditional way of doing heart surgery where breast bone is cut to expose the heart. Commonly performed heart surgeries through this latest technique are:

1. Coronary Artery Bypass surgery (Mid CABG, MICAS)

2. Valve replacement surgery (Aortic valve, Mitral valve)

3. Correction of congenital defects (ASD, VSD)

Minimally Invasive Direct Coronary Artery bypass surgery (MIDCABG) or Minimally invasive coronary artery surgery (MICAS) for patients with blocked Coronary arteries in two or more vessels bypass grafting is done to restore the blood supply to the myocardium (heart). The bypass is constructed using arteries and veins harvested from the patient's chest and legs. A combination of artery plus vein or all arterial grafts is used for restoring blood supply. The bypass is constructed while the heart is beating (off-pump bypass surgery). Hence the complications of stopping the heart or subjecting the patient to a cardiopulmonary bypass machine are not there.

A small 5 cm incision is made just below the left breast region and the heart is approached through rib spaces. “No bone is cut”. Hence pain related to bone healing or infection is not there. Elderly and diabetic patients who have poor wound healing benefit because the healing is much faster.

Bypass is done with specialised instruments. Once the bypass grafters are constructed the flow across vessels is checked using TTFM (Transit Time Flow Measurement). The patient's recovery with minimally invasive surgery is smooth and quick.
