Contrast‐enhanced excimer laser stepwise approach during PCI for resistant coronary lesions

The treatment of resistant coronary lesions (RCL) is a great challenge for interventional cardiologists. The excimer laser coronary atherectomy (ELCA) is a plaque modification tool based on a main mechanism of photomechanical effect leading to mechanical disruption of the plaque. Contrast dye injection during laser delivery has demonstrated to enhance its power.
