Reduced hospital stay, faster recovery, and improved cosmetic outcome


Patients suffering from Coronary Artery Disease can now enjoy long term freedom through the benefits of Minimally Invasive Coronary Artery Bypass Surgery. Today’s evolving surgical technique allows the surgeon to safely and effectively suture coronary artery bypass grafts in place without leaving a big scar and offer the benefits of beating heart surgery. Young women in particular will appreciate the better cosmetic results of Minimally Invasive Coronary Artery Bypass Procedure with minimal scar.


Scientific evidence suggests that patients with a critical block in a single blood vessel may opt for a stent however in case a patient is suffering from more than one blocked blood vessel in the heart it is prudent to prefer a by-pass surgery for long term superior quality of life as stents get blocked themselves in over 7% patients.


In Coronary Artery Bypass Surgery an incision is made in the chest as the heart continues to beat. Positioning and stabilization instruments lift and hold the heart and then stabilize a portion of the heart’s surface where the bypass graft will be sutured in place, all as the heart continues to beat. A stabilization system makes it possible to avoid use of the heart-lung machine by enabling the surgeon to carefully work on the patient’s heart while it continues to beat.


Minimally invasive coronary artery surgery is also called limited access coronary artery surgery and requires a cut of hardly 6 inches on the left or right side of the skin on the chest. Like CABG, the surgery is done to reroute, or “bypass,” blood around coronary arteries that are clogged by fatty buildups of plaque to improve the supply of blood and oxygen to the heart. In this procedure, a surgeon performs coronary bypass through a smaller incision in the chest, often with the use of robotics and video imaging that help the surgeon operate in a small area. This technique uses a combination of small holes or “ports” in the chest and a small incision made directly over the coronary artery to be bypassed. The heart surgeon usually detaches an artery from inside the chest wall and re-attaches it to the clogged coronary artery farthest from the occlusion. The surgeon views and performs the attachment directly, so the artery to be bypassed must be right under the incision.


These developing techniques have not replaced conventional coronary artery bypass grafting (CABG) procedures but they are increasingly used as technologies developed to support them.


Potential Benefits of Minimal Invasive Coronary Artery Bypass Surgery


  • Shorter length of hospital stay: Shortened post-operative intensive care unit (ICU) stay and shortened total hospital stay lead to shorter recovery back to normal life.

  • Fewer blood transfusion requirements/less use of banked blood or blood products

  • Improved Cosmetic outcomes: Less invasive and thus less traumatic for the patient because it is off-pump procedure no sternotomy and better cosmetic results

  • Available to more patients: Expanded indication patients who might be candidates for a minimal access procedure

  • Left internal mammary artery–left anterior descending (LIMA-LAD) anastomoses under direct vision with proven, excellent long-term results

  • More competitive with percutaneous procedures

  • Potential avoidance of neurocognitive decline

  • Lower cost
