The objective of this study was to analyze the feasibility and safety of transradial catheterization in patients with remote surgical cardiac revascularization. Selective catheterization of coronary bypass grafts might be more difficult and time-consuming from the radial artery as compared to the femoral route. This special patient subset has been either excluded or underrepresented in previous studies. Retrospective review was made of 304 cardiac diagnostic procedures performed from January 2001 through December 2004 in patients with coronary artery bypass grafts in a single center. Patients had to be considered eligible for both transradial and transfemoral approach to be included. Cases with double internal mammary or gastroepiploic grafts were excluded. Selection of the arterial access was individualized according to operator preferences. Among diagnostic cases, transradial access was attempted as first choice in 151 cases (left radial in 133) and transfemoral in 154. Total procedural time (41 +/- 22 vs. 40 +/- 23 min), fluoroscopy time (15 +/- 10 vs. 18 +/- 13 min), and dye volume (180 +/- 64 vs. 192 +/- 73 ml) were similar. Crossover rates were 4.0% in the transradial group and 1.3% in transfemoral (P = 0.28). Only two patients in transradial group needed transfemoral access because of failure to catheterize a bypass graft. Transradial angiography of coronary bypass grafts can be performed with similar success rates as compared with transfemoral procedures and without a significant time delay.
