[An anastomosis assist mirror; a new device for off-pump coronary artery bypass].

An anastomosis assist mirror for off-pump coronary artery bypass (OPCAB) is described. This new device is designed to make a view of the circumflex coronary artery which is often troublesome to access during OPCAB. It is composed of 3 parts: a small circular mirror, a paper clip and a flexible arm between the mirror and the clip. The paper clip is situated at an edge of a sternal retractor. The mirror is positioned beside the sheer surface of the lateral wall of the heart by regulating the flexible arm. It shows a flat, reflective view of the anastomotic site and makes an anastomosis easy. The device enables us to avoid excessive manipulation on the heart and hemodynamic instability, thereby reducing unnecessary volume overload, inotropic drugs or mechanical cardiac assistance.
