Exision of the autograft, view from the assitant.
The right (1) and left (2) coronary ostia are presented. The small (*) right superior septal artery is a clear hemorragic threat and should be ligated, clipped or treated with the diatermy. The (2) conus branch is not a problem in this case.
The anterior descending artery (4) courses normally. Carefull observation of the extraction zone of the autograft evidentiates four small branches of the lad and the septal artery.
