A safe technique of exposing of a "hidden" left anterior descending artery.

We describe a safe, easy, and fast technique of exposing the left anterior descending artery (LAD), when this is embedded under the myocardium or excessive epicardial fat tissue, during coronary artery bypass grafting (CABG) or off-pump coronary artery bypass (OPCAB). The vessel is opened as distal as possible, then a fine intravascular probe is introduced retrogradely. Through palpation of the tip, the course of LAD is confined together with the site of distal anastomosis formation. The suggested technique minimizes the risk of injuring the vessel or ventricles, reduces the ischemia-time, and allows the performance of anastomosis as paroximal as possible in the cases of OPCAB with embedded LAD.
