Minimally invasive cardiac surgery make multivessel MICS CABG safe, effective and more widely available." The Minimally Invasive Cardiac Surgery was invented by Dr Joseph T McGinn, Jr. The first minimally invasive heart cardiac surgery was performed in the United States on January 21, 2005 at The Heart Institute at Staten Island University Hospital in Staten Island, New York by a team led by Dr. Joseph T. McGinn. This technique is an off-pump coronary artery bypass surgery. The procedure is much less invasive than traditional bypass surgery because it is performed through three small incisions rather than the traditional sternotomy. Since its first procedure, over
