Minimally invasive cardiac surgery

Minimally invasive cardiac surgery, encompasses various aspects of cardiac surgical procedures (aortic valve replacement, mitral valve repair, coronary artery bypass surgery, ascending aorta or aortic root surgery) that can be performed with minimally invasive approach either via mini-thoracotomy or mini-sternotomy.^[1][2] MICS CABG (Minimally Invasive Cardiac Surgery/Coronary Artery Bypass Grafting) or the McGinn technique is heart surgery performed through several small incisions instead of the traditional open-heart surgery that requires a median sternotomy approach. MICS CABG is a beating-heart multi-vessel procedure performed under direct vision through an anterolateral mini-thoracotomy.^[3]

Advantages of minimally invasive heart surgery are less blood loss, reduced post-operative discomfort, faster healing times and lower risk of infections, reduced duration of mechanical ventilation as well as eliminating the possibility for sternal non-union. This procedure makes heart surgery possible for patients who were previously considered too high risk for traditional surgery due to age or medical history.^[4][5] Patients referred for this procedure may have coronary artery disease (CAD); aortic, mitral or tricuspid valve diseases; or previous unsuccessful stenting.
