Background Coronary revascularization surgery does not traditionally employ angiography to assess procedural success. Early graft failure is reported up to 30% in one year (JAMA Nov 2005) may relate to technical errors or conduit problems. We hypothesize that intra-operative assessment of graft by angiography identifies graft defects and may improve the long term graft survival. Methods We have developed one of the first hybrid operation room in the USA. In one year period 203 consecutive patients (age:63+/-16, M/F:126/39) underwent coronary revascularization with angiography before decannulation. Results Of 436 grafts, 72 angiographic defects were detected in 69 grafts (17% of total grafts). There were 11% conduit defects, 3% anastomotic defects, and 3% target vessel error. Of 72 defects, 25/72 defects required minor revision, 47/72 required either surgical or percutaneous intervention. Intra-operative angiography added an average 20+/-12 minutes to the surgery and 112+/-56 ml contrast. Renal function at 24hours and 48 hours after procedure did not vary significantly between patients who did vs. those did not have revisions. There were no significant differences in cardiopulmonary bypass time, aortic cross clamp time, and length of hospital stay for patients who underwent revision compared to those who did not. Renal function, bleeding complication, transfusion were similar in patients with percutaneous vs. surgical revision. Conclusions Intraoperative graft angiography performed at the time of CABG identifies graft defects, allowing for immediate surgical or percutaneous revision. Long-term study is in progress to assess whether intra-operative completion angiography decreases the rate of early graft failure.
