Q. Advantages of choosing left radial artery over right radial artery during trans-radial PCI are all except? A. Prevalence of subclavian artery tortuosity and radial artery loops are three times more common in right radial artery B. Hooking of LIMA is easier from left radial artery C. Learning curve is short in left radial route than right D. Incidence of radial artery spasms is more in right radial artery Answer: D. Incidence of radial artery spasms is more in right radial artery Explanation: PCI from left radial route has many advantages as compared to right artery. Prevalence of radial artery loops and subclavian artery tortuosity are more three times more common on right side. Learning curve is longer in right radial artery and hooking of left internal mammary artery (after CABG) is difficult from the right radial route because it involves crossing to the opposite side from the aortic arch. However, the incidence of radial artery spasms during the procedure is
