NCT05649488

Brief 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.

Study Arms (2)

Experimental group

EXPERIMENTAL

184 patients were enrolled in the experimental group

Device: Intracoronary lithotripsy balloon catheter and Intracoronary lithotripsy apparatus

Optical Coherence Tomography Subgroup

OTHER

70 patients in the test group were enrolled in the OCT subgroup.

Device: Intracoronary lithotripsy balloon catheter and Intracoronary lithotripsy apparatusDevice: Dragonfly Opstar Imaging Catheter

Interventions

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

Experimental groupOptical Coherence Tomography Subgroup

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.

  • Patients who can understand the purpose of the trial, voluntarily participate and sign the informed consent form, and are willing to undergo angiography, OCT and clinical follow-up.
  • The target lesion was primary and in situ coronary artery disease.
  • Target lesion length ≤40 mm, target lesion reference vessel diameter 2.25-4.0 mm (visual inspection).
  • The target lesion diameter stenosis ≥70% or ≥50% (visual inspection) with evidence of ischemia.
  • Clear, high-density shadows can be seen both when the heart is beating and when it is not.
  • TIMI flow grade 3(allowing predilation) in the target vessel before use of the test equipment.
