For patients who have undergone CABG, repeat procedures are sometimes necessary. Six to ten percent of CABG procedures are now re-operations. However, re-operative mortality rates are two or three times those of the initial procedure and range from two to ten percent for second operations and up to fifteen percent for third and subsequent operations. Patients undergoing repeat procedures generally have more advanced coronary artery disease rendering the revascularisation process less effective. (Cath-Lab Digest, Jan/Feb, 1997).
