Minimal access aortic arch replacement

Minimally Invasive Coronary Artery Surgery or MICAS CABG is a procedure that is done by making several small incisions. Also known as the McGinn technique, this is a beating heart multi-vessel procedure performed through an anterolateral mini thoracotomy. Some of the advantages of MICAS are minimal blood loss, fast recovery and healing, and fewer infections, besides the reduced risk of the deep sternal wound. MICAS serves as a shot in the arm for high-risk patients for whom traditional open-heart surgery would increase the complications.

Minimal access aortic arch replacement


A great alternative to traditional surgery, MICAS is recommended for patients suffering from the following conditions:

  • Coronary Artery Disease
  • Mitral Valve Repair
  • Mitral Valve Replacement
  • Aortic Valve Replacement
  • Atrial Septal Defects
  • Maze procedure for atrial fibrillation
  • Hybrid Coronary Revascularization
  • Tricuspid valve repair or replacement

How Is MICAS CABG Performed?

One of the first steps during MICAS is to lower the blood pressure to 90-100 systolic to reduce the stress on the aorta. MICS-CABG is then performed through an incision of 5 to 7 cm in the 4th Intercostal Space, but a few patients may need a thoracotomy in the 5th ICS. With the help of a soft tissue retractor, the surgeon will be able to access the affected region and fix the condition.
