Precision incision: robotic coronary revascularization via 3.9-cm minithoracotomy.

Coronary artery bypass grafting remains the treatment choice for coronary artery disease; but sternotomy, the most commonly used approach, compromises its benefits with postoperative morbidity, higher complication rates, and prolonged length of hospital stay. Despite this, minimally invasive and robotic-assisted technology has not been adopted or widely embraced because supporting literature on robotic-assisted coronary artery bypass grafting is extremely limited. Since 2005, the cardiothoracic surgical team at our institution has been developing and maturing an effective method using robotic harvesting of the left internal mammary artery (LIMA) and beating heart surgery through a minithoracotomy for coronary revascularization.
