Clinical Trial on the Treatment of Stent Underexpansion Caused by Calcification Using Intravascular Lithotripsy

The intravascular lithotripsy can intermittently release acoustic pressure waves at the site of vascular calcification lesions, thereby achieving the goal of rupturing calcified plaques; After the rupture of calcified plaques, the vascular calcification lesions can be fully dilated with the help of lower balloon inflation pressure.

High pressure balloon dilation, as the main method for traditional treatment of insufficient stent expansion caused by calcification, has a good therapeutic effect on insufficient stent expansion caused by calcification
