        Transradial Coronary Intervention: Comparison of the Left and Right Radial Artery Approach

        김장영,윤정한,정일형,왕희승,정현숙,유병수,이승환,최경훈 대한심장학회 2006 Korean Circulation Journal Vol.36 No.12

        Background and Objectives:We evaluated the efficacy and safety of the left transradial approach as comparedto the right radial approach when performing transradial coronary intervention. Subjects and Methods:Weperformed the transradial coronary intervention in 711 cases via the left approach (Lt. group) and in 614 casesvia the right approach (Rt. group) for patients with a normal Allen’s test of both arms. We evaluated the proceduralsuccess rate, the crossover rate, the puncture time, the total procedural duration, the fluoroscopy time, theamount of contrast agent used and the local vascular complications of both groups. Results:The baseline clinicaland angiographic profiles were comparable between both groups. The puncture time, the amount of contrast agentused, choice of the guide catheter and local vascular complications were similar for the two groups. There was nodifference in the procedural success rate (Rt. group; 96.4% vs. Lt. group; 96.2%, p=NS). However, there was tendencyfor a higher success rate via radial access for the Lt. group than for the Rt. group (Rt. group; 91.9% vs. Lt.group; 93.5%, p=0.056). The crossover rate was lower for the Lt. group than for the Rt. group (2.7 % vs. 4.6%,respectively; p=0.04). The total procedural time (32.3±15.4. vs. 30.7±17.6 min, respectively; p=0.03) and fluoroscopytime (16.9±12.6 vs. 13.9±7.9 min, respectively; p<0.01) were shorter in the Lt. group. The number ofguide catheters used was higher in the Rt. group compared to the Lt. group (1.21±0.48 vs. 1.08±0.33, respectively;p=0.04). Conclusion:The left radial approach may provide increased procedural efficacy for transradial PCIcompared to the right radial approach along with similar complications.
