Summary

This is a prospective, multi-center, single-group target value clinical trial, which will be carried out in many clinical trial institutions in China. A total of 184 subjects (70 of them are OCT subgroups) are planned to be enrolled, all subjects were treated surgically with intracoronary lithotripsy using a balloon dilatation catheter and intracoronary lithotripsy apparatus after a single-group registration, clinical follow-up was carried out within 7 days after operation or before discharge, 1 month and 6 months after operation. The success rate of operation was taken as the main end point to verify the effectiveness of balloon dilatation catheter and intracoronary lithotripsy apparatus.

Detailed description

This is a prospective, multi-center, single-group target value clinical trial to recruit patients with coronary artery calcification, coronary artery calcification was pretreated with balloon dilatation catheter and intracoronary lithotripsy apparatus made by Shanghai Blusail Boyuan Medical Technology Co. , Ltd. , to verify the safety and efficacy of balloon dilatation catheter and intracoronary lithotripsy instrument for intravascular preconditioning of coronary artery calcification lesions. This trial will be carried out in many clinical trial institutions in China, and a total of 184 subjects (70 of them are OCT subgroups) are planned to be enrolled, all subjects were treated surgically with intracoronary lithotripsy using a balloon dilatation catheter and intracoronary lithotripsy apparatus after a single-group registration, clinical follow-up was carried out within 7 days after operation or before discharge, 1 month and 6 months after operation. In this study, the success rate of operation was taken as the main end point to verify the effectiveness of balloon dilatation catheter and intracoronary lithotripsy apparatus. A clinical summary report was issued for registration of the product 1 month after completion of postoperative follow-up, based on which a 6-month postoperative follow-up was performed to assess its safety. The secondary end points were angiographic success, device success, target lesion failure at 1 and 6 months, severe angiographic complications, MACE events at 1 and 6 months, serious adverse events and adverse events, and device defects. In the OCT Subgroup, the secondary end points were the minimum stent area (MSA), the minimum stent lumen diameter (MLD), the lumen acquired diameter, the lumen acquired area, and the lumen acquired rate of the immediate postoperative, the expansion rate of the stent, and the incomplete adherence rate of the stent beam.

Conditions

• Coronary Artery Disease
• Intravascular Lithotripsy

Interventions

Type	Name	Description
DEVICE	Intracoronary lithotripsy balloon catheter and Intracoronary lithotripsy apparatus	Introduction: After the preparation, release the intracoronary lithotripsy balloon catheter to the area to be treated and release the shock wave pulse for treatment. After the balloon reaches the predetermined position, use angiography to lock the position and fill the balloon to 6 atm. After the shock wave pulse therapy, the balloon was expanded to 8 atm according to the balloon compliance table and lasted for 10s. After the treatment, unload the balloon pressure, wait for the blood flow to recover, and repeat the second treatment after an interval of one minute, two cycles, releasing a total of 20 shock wave pulses as a treatment cycle. Therapeutic apparatus specification: IVL-HVG-C01； Specifications of balloon catheter: C20012, C20015, C22512, C22515, C25012, C25015, C27512, C27515, C30012, C30015, C32512, C32515, C35012, C35015, C37512, C37515, C40012, C40015
DEVICE	Dragonfly Opstar Imaging Catheter	OCT (optical coherence tomography) measurement using Dragonfly Opstar Imaging Catheter was performed in the OCT subgroup before or after the treatment of intracoronary lithotripsy balloon catheter and intracoronary lithotripsy therapeutic instrument, or after stent placement.
