Case Summary

Here we present our initial experience with the shock wave IVL system. We assume it an innovative technology where the calcified lesions, which were not amenable with other methods, were treated, and there appear to be lesser complications like perforations and no-reflow. In literature, S-IVL is found to be useful when the calcium is circumferential and superficial as well as deep. It¡¯s efficacy in large vessel diameter and eccentric calcium is questionable. In our case, we found it to be useful for large diameters, deep calcium, and eccentric lesions as characterized by IVUS imaging.
