Techniques of Minimally Invasive Internal Mammary Artery Harvest
Despite the wide application of video-assisted techniques in thoracic surgery, only a few procedures, such as pericardial window and ligation of a patent ductus arteriosus, have been performed by cardiac surgeons (1–3). Owing to the growing clinical interest in minimally invasive coronary surgery, several technical approaches have recently been proposed to perform a left internal mammary artery to left anterior descending (LIMA-LAD) anastomosis on the beating heart through a small anterior thoracotomy. One of the concerns of these less invasive techniques involves the dissection of the IMA. This chapter discusses the various techniques currently used to harvest the IMA with a particular emphasis on the video-assisted (or thoracoscopic) approach.
