Primary Percutaneous Coronary Intervention Using BaLloon-Assisted Sliding and Tracking (BLAST) of Diagnostic Catheter to Negotiate Double Hairpin Loop of Radial Artery

During transradial intervention, sharp edge of the guide catheter tip may act like a "razor-blade" and can prevent the catheter navigation especially in situation like double hair pin loop. Here, we report primary percutaneous coronary intervention (PCI) through diagnostic catheter using an innovative technique, balloon-assisted sliding and tracking (BLAST), to overcome this double hairpin loop, thus saving time and contrast volume.
