Trial summary

Coronary artery disease is caused by narrowing of the artery lumen. Treatment with Percutaneous Coronary Intervention (PCI) may be needed. This is a minimally invasive procedure used to treat narrowed or blocked coronary arteries. Sometimes a stent is placed to keep the artery open. Read more about this study

About this study

Official title: ShockFast Intravascular Lithotripsy Device for Treatment of Calcified Coronary Lesions, a Prospective, Randomised, International Trial: ShockFast IVL Trial

Coronary artery disease is caused by narrowing of the artery lumen. Treatment with Percutaneous Coronary Intervention (PCI) may be needed. This is a minimally invasive procedure used to treat narrowed or blocked coronary arteries. Sometimes a stent is placed to keep the artery open. If the lesions in the coronary artery are calcified, this may cause difficulties for successful stent placement. The calcified plaques can be fractured via intravascular lithotripsy (IVL) with devices like ShockWave IVL and ShockFast IVL. The aim of this study is to compare the this relatively new ShockFast IVl with the more widely used ShockWave IVL.

Read the detailed description

Coronary calcified lesions have evolved as one of the most challenging indications for coronary percutaneous interventions (PCI). Different dedicated devices have been recently introduced into the market to improve procedural success in this challenging PCI population. Shockwave Intravascular Lithotripsy, (Shockwave IVL), Shockwave Medical, SC, CA, USA, was the first intracoronary device that used sonic pressure to fracture intracoronary calcium. The device safety and efficacy has been proved in a series of clinical trials. ShockFast intravascular lithotripsy (ShockFast IVL), Shunmei medical, Shenzhen, China, is a new dedicated device to treat intracoronary calcium that makes use of sonic pressure waves to fracture calcified plaques. ShockFast IVL has recently obtained CE mark approval for this indication.

The aim of this study is to compare this new lithotripsy device (ShockFast IVL) with the existing and widely used lithotripsy device that uses the same principle of action, the Shockwave IVL, Shockwave Medical, SC, CA, USA.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Shockwave IVLDevice

    Treatment of subjects with coronary calcified lesions with an interventional procedure that utilizes a fluid-filled catheter connected to an energy source that generates mechanistically tuned ultrasonic acoustic pressure waves - or Shockwaves - for modification, fracture, and fragmentation of vascular calcification.

  • Shockfast IVLDevice

    Treatment of subjects with coronary calcified lesions with an interventional procedure using a dedicated device to treat coronary calcified lesions by offering precise control of sonic pressure waves for safe fracture calcium deposits within the artery walls, thus maintaining vessel flexibility and promoting smoother stent placement. The ShockFast device has an improved crossing profile and 2 lengths of the catheter: 12 and also 15mm compared to ShockWave which has only 1 length.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Stent area post PCI measured at the minimal lumen area during initial procedure, evaluated by OCT

    Measured: Hospitalisation (during procedure)

Secondary outcomes (3)
  1. Target lesion failure defined as cardiac death, target-vessel myocardial infarction and target-lesion revascularisation at discharge and 30 days

    Measured: 30 day follow-up

  2. Angiographic success

    • Defined as a successful stent delivery with diameter of stenosis post PCI of <50% without severe dissection (type D-F), perforation, abrupt vessel closure or persistent less than Thrombolysis in Myocardial Infarction (TIMI)-3 flow.
    • By collecting data through angiography and imaging:
    • Minimal lumen area post stenting
    • Residual area of stenosis
    • Residual diameter of stenosis <30%
    • Residual diameter of stenosis <50%
    • Optical Coherence Tomography (OCT) measured under expansion (<80% of the reference lumen area)
    • Post-IVL acute area gain (measured at the minimum lumen area post IVL)
    • Number of visible calcium cracks post IVL
    • Severe coronary dissection post IVL (type C-F)

    Measured: Hospitalisation (during procedure)

  3. Device success

    Defined as success of the device to cross and fully expand

    Measured: Hospitalisation (during procedure)

Questions about this trial

What is this clinical trial studying?

A study testing Shockwave IVL and Shockfast IVL in people with Coronary Arterial Disease and Calcified Coronary Artery Disease, run by Shunmei Medical at 13 sites in 4 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 13 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 29 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 13 sites in Poland, Spain, France, Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Jasper Yang (008615363476127, cm@shunmed.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Stent area post PCI measured at the minimal lumen area during initial procedure, evaluated by OCT (time frame: Hospitalisation (during procedure)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Sep 2026.
