Abstract:
Guide catheter exchange over coronary guidewire can be challenging, yet is necessary in certain clinical scenarios. At the same time, maintaining coronary guidewire position across a predilated lesion is important to prevent vessel lumen closure. We present a technique of guide catheter exchange over a coronary guidewire with GuideLiner support.
