Comparison of fluoroscopy time in different catheter-engagement approaches to graft vessels in post-coronary artery-bypass graft angiography

摘要

Background: Although there is ongoing progress in coronary artery-bypass graft (CABG) surgery and percutaneous coronary intervention techniques and supplies, the risk of cardiac complications remains high compared with the normal population. Aim: In this study, our aim was to compare fluoroscopy times in engagement of three different catheters in saphenous vein grafts (SVGs) in post-CABG patients undergoing angiography. Methods: This was a single-center, cross-sectional, comparative study. We evaluated patients with previous CABG referred for invasive coronary diagnostic angiography. Patients having had SVG–obtuse marginal artery, SVG–diagonal, and SVG–posterior descending artery CABG were included. All patients underwent diagnostic angiography by each of a right diagnostic Judkins catheter, right modified Amplatz catheter, and right guiding Judkins catheter. Demographics and clinical history of patients and fluoroscopy time in different groups were evaluated. Results: A total of 61 patients were evaluated. The distribution of baseline characteristics in the three groups of our study was normal. Mean fluoroscopy time in SVG–obtuse marginal artery was 25.70±6.70 seconds in group A, 22.23±6.51 seconds in group B, and 17.35±7.82 seconds in group C. Mean total fluoroscopy time was 86.35±16.28 seconds in group A, 73.80±10.00 seconds in group B, and 51.90±10.22 seconds in group C, which was significant ( P 0.001). Conclusion: Our data suggest that when we use the guiding Judkins catheter, fluoroscopy time decreases. However, more evaluations are needed with larger-scale studies and identification of other variables.
