BACKGROUND: In high-expertise transradial (TR) centers, the radiation exposure to patients during coronary angiography (CAG) is equivalent to transfemoral use. However, there is no definitive information during TR-CAG regarding the use of a single, dedicated catheter to impart less radiation exposure to patients.
OBJECTIVE: We compare the radiation exposure to patients during right TR-CAG with Tiger II catheter (Terumo Interventional Systems) vs Judkins right (JR) 4.0/Judkins left (JL) 3.5 catheters (Cordis Corporation).
METHODS: This multicenter, randomized, and prospective trial included 180 patients submitted to right TR-CAG, with the primary objective of observing radiation exposure to patients through the measurement of fluoroscopy time, air kerma (AK), and dose-area product (DAP) using Tiger II (group 1) vs JR 4.0 and JL 3.5 Judkins catheters (group 2). Secondary outcomes included contrast volume usage and the need to use additional catheters to complete the procedure (the crossover technique).
RESULTS: Group 1 demonstrated reduced fluoroscopy time (2.47 ± 1.05 minutes in group 1 vs 2.68 ± 1.26 minutes in group 2; P=.01) and non-significant reduction of AK (540.9 ± 225.3 mGy in group 1 vs 577.9 ± 240.1 mGy in group 2; P=.34) and DAP (3786.7 ± 1731.7 μGy•m² in group 1 vs 4058.0 ± 1735.4 μGy•m² in group 2; P=.12). Contrast volume usage (53.46 ± 10.09 mL in group 1 vs 55.98 ± 10.43 mL in group 2; P=.13) and the need for additional catheters (5.56% in group 1 vs 4.44% in group 2; P>.99) were similar between groups.
CONCLUSION: The Tiger II catheter was able to reduce radiation exposure to patients submitted to TR-CAG through a significant reduction in fluoroscopy time.
