Robot-Assisted Coronary Artery Bypass Grafting

Dr. Geirsson 
Dr. Arnar Geirsson, Director of our Minimally-Invasive Cardiac Surgical Program, has established excellent results using a combined robotic and catheter-based, minimally-invasive approach towards treating coronary artery disease. Dr. Geirsson uses the state-of-the art da Vinci surgical robot to harvest the left internal mammary artery from within the chest wall and then grafts it to the left anterior descending coronary artery, the most important blood vessel on the heart, without splitting the breastbone or using the heart-lung machine. This single graft has been shown to be the most important aspect of coronary revascularization in terms of long-term outcomes and remains the most important advantage with surgery. Any other diseased coronary arteries are then treated with angioplasty and stenting, performed with a catheter threaded up your leg or arm vessels. This exciting, innovative approach combines the advantages of surgery and catheter-based intervention, providing complete coronary revascularization, including the left internal mammary artery-to-left anterior descending coronary artery graft, without splitting the breastbone or using the heart-lung machine.


Dr. Geirsson is also conducting basic science research on the biology of how mitral valve prolapse and mitral valve regurgitation forms, specifically on the impact of growth factors on the mitral valve. This research could lead to new therapies in the treatment of heart valve disease.
