Procedural success rate was 100%. Thirteen patients (9%) underwent same‐procedure multivessel interventions for the right and left coronary artery. Among the group of 46 patients undergoing bifurcation PCI, 35 (76%) bifurcated lesions were treated with a kissing balloon technique, one patient had a saphenous vein bypass graft lesion requiring filter wire placement prior to intervention, nine (6.1%) patients required rotational atherectomy, thrombus‐aspiration catheters were used in 19 (12.8%) patients, fractional flow reserve (FFR)‐guided PCI in 10 (6.7%) patients, alcohol septal ablation in three (2%) patients. Ten (6.7%) cases of chronic total occlusion were successfully treated in nine (6.1%) patients using the hydrophilic catheter. No radial artery site complications was noted.</p> </sec> <sec id="ccd25508-sec-0005" sec-type="section"> <title>Conclusion</title> <p>The use of sheathless guiding catheters is a safe, effective method for PCI via TRA in small radial arteries without catheter‐related complications. © 2015 Wiley Periodicals, Inc.</p> </sec> </abstract>
