COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Devices - Shockwave Coronary Lithoplasty System

Experimental: Shockwave Coronary Lithoplasty System - Patients receive Lithoplasty treatment prior to placement of coronary stent. IVUS or OCT documents patency pre and post Lithoplasty. Patient is followed for patency at discharge, 30 days and 6 months following treatment.


Treatment: Devices: Shockwave Coronary Lithoplasty System
Lithotripsy shockwaves are used to fracture calcified lesions in the coronary arteries

Summary
Brief summary
The objective of this clinical trial is to study the early safety and feasibility of the
Shockwave Coronary Lithoplasty System. To demonstrate that the Shockwave device can safely
and effectively deliver localized shockwave energy for balloon dilatation of calcified,
stenotic, de novo coronary lesions.
