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.

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
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.
Eligibility Criteria
You may qualify if:
- Age 18-80 years, male or non-pregnant female.
- Evidence of symptomatic ischemia, stable or unstable angina, or MI for more than 7 days.
- 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.
- The target lesion was the only calcified lesion to be treated with the shock wave, and the non-target lesion needed to be treated successfully before the target lesion.
- Suitable for patients undergoing metallic stent implantation
You may not qualify if:
- Severe myocardial infarction occurred within 7 days before operation.
- At the same time, the lesions were treated with rotational grinding or special balloon (chocolate balloon, nicked balloon, cutting balloon, double guide wire balloon, spinous process balloon, etc.).
- NYHA Class III or IV.
- Left ventricular ejection fraction \<35% .
- The target lesion was expected to be treated by fully biodegradable stent implantation, drug balloon dilatation and PTCA.
- Uncontrollable severe hypertension (systolic blood pressure \>180 mmHg or diastolic blood pressure \> 110 mmHg).
- Severe hepatic and renal impairment, transaminase more than 3 times the upper limit of normal, serum creatinine \> 2.5 mg/dL (221 μmol/L), or chronic kidney failure requiring long-term dialysis.
- Preoperative hemoglobin \<100 g/l.
- Platelet count \<60×109/L.
- Cerebral Stroke occurred within 6 months of enrollment, excluding transient ischemic attack (TIA) and lacunar infarction.
- A history of active peptic ulcer or upper gastrointestinal bleeding within 6 months before enrollment.
- Patients known to be allergic to heparin, contrast media, aspirin, clopidogrel and anesthetics.
- Definite diagnosis of malignancy or life expectancy would be less than 12 months.
