Abstract
Introduction
Coronary angiography is regarded as the gold standard in evaluating graft patency, Multi-slice CT (MSCT) which enable rapid imaging of cardiac structures, including coronary arteries may be a less invasive technique. Therefore in our institution a prospective pilot study was performed combining these procedures.
Patients and methods
Starting from July 2004 a study was done with 13 patients. They received TAR using composite left internal thoracic artery (LITA) and left radial artery (RA) as T-graft. Intra-operative angiography was performed in these patients to confirm graft patency. Follow-up control (9–21 months) was performed with exercise Ergometry and 64 slides MSCT.
Result
Mean procedure time for intra-operative angiography was 13.7 ± 7.3 min and mean fluoroscopy time was 6.2 ± 4.6 min. In one patient, RA-marginal artery side to side anastomoses was stenosed and had to be revised. And in another, there was a kinking of the LITA and was corrected. At follow-up, exercise ergometry showed no signs of angina or ECG-changes in all patients. MSCT showed occluded radial artery grafts in two patients. In two other patients interpretation was difficult due to resolution reasons. In all patients the LITA graft was patent.
Conclusion
The intra-operative graft angiography can be performed in patients undergoing TAR easily. MSCT can be used for post-operative less-invasive angiography with limitations in patients with small graft/coronary diameters and arrhythmias. However, this study shows that an interdisciplinary cooperation is a new possibility toward quality control during and after TAR.
