Description:
The development of endoscopic surgical techniques with robotic assistance has enabled this technology to be used for coronary artery bypass grafting, known as totally endoscopic coronary artery bypass surgery (TECAB) . Following deflation of the lung, small-port incisions are made at three intercostal spaces through which one robotic arm carrying the endoscope and two arms with surgical implement attachments are introduced. Grafts are harvested from suitable donor sites, and anastomosis is achieved across the diseased coronary artery in one or more vessels.
TECAB treatment of the beating heart is carried out using a stabilisation device, consisting of two branches like those used in the MIDCAB procedure, that hold the site for anastomosis steady while the heart continues to beat and removes the need for cardiopulmonary bypass. The stabilisation device requires an additional chest incision to be made when it is used.
