This is new form of surgery, where we do it in Cherney surgery, Cardiac Surgery almost all type of surgeries can be performed. Not all of course around 80% of the operation can be done without doing a conventional surgery that is making a big cut on the chest from here to here. What we do is make 1 or 2 inch small cuts on right or left side of the chest and do the same complex operation which otherwise would be done through a midline enormity. The advantage of this is that patients are discharged much earlier from the hospital, may be in 5-4 days. Then the pain is much less. So, these are various advantages of Minimally Invasive Cardiac Surgery.
