Notes:
The invasiveness of the standard open CABG inspired research on minimally invasive techniques such as the PortCAB, MIDCAB and TECAB. The TECAB (totally endoscopic coronary artery bypass) is performed with the help of a robot. The procedure is performed through small 5mm incisions in the thoracic wall of the patient on a beating heart, while the traditional CABG surgery procedure is performed using a heart lung machine. The benefits with TECAB is the less invasiveness both due to smaller incisions and that the heart is beating, this also leads to shorter recovery time for the patient, shorter hospital stay and much less scarring and tissue damage than the sternotomy gives. The considerations with the TECAB is the rediced force feedback, loss of overview and the resulting loss of precision. The force feedback was an important part in locating the lima in open procedures as the surgeon could feel the arterys location with his fingers. And as the only view comes from an endoscope he does not have the same overview as the open procedure gives.
