Outcomes of excimer laser-contrast angioplasty for stent underexpansion

Introduction Stent underexpansion is associated with increased risk of in-stent thrombosis and restenosis. Several management options exist beyond high-pressure non-compliant balloon post-dilation; however, there is no consensus on the best approach. Excimer laser (EL) causes a thermo-mechanical process of expanding and imploding vapour bubbles and has been used for lesion modification1,2. Injection of iodinated contrast during higher power...
