Pulse IVL to open calcified coronary vessels in CAD

Official title: AVS Pulse Intravascular Lithotripsy™ (Pulse IVL™) to Open Vessels With Calcific Walls and Enhance Vascular Compliance and Remodeling for Coronary Artery Disease - A First-in-Human (FIH) Study

Run by Amplitude Vascular Systems, Inc. · NCT07510438 · Data updated 2026-11-12

A small, early feasibility study tests the Pulse Intravascular Lithotripsy system in adults with coronary artery disease to see if it can safely open calcified arteries and improve vessel compliance.

Is this trial a fit for you?

Likely a good fit

Adults 18+, with a single de novo coronary lesion 50-99% stenosis (or 70-<100% with ischemia) in a native vessel and adequate LV function (LVEF ≥35%).

Probably not a fit

Patients with recent MI (within 30 days), NYHA class III/IV heart failure, severe renal impairment, or recent stent placement in the target vessel may not benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, open-label, multi-site feasibility study enrolling up to 15 adults with native CAD. The study uses the Pulse IVL system to treat a single de novo coronary lesion with significant narrowing. Participants must have adequate heart function and no recent major heart attack, with lesion length limited to 44 mm. Safety and preliminary effectiveness are the primary focus. No control group is described, and the trial is conducted at several Australian centers.

Why it matters

Potential benefit: If successful, the approach could offer a new option to safely plaque-burst calcified vessels and potentially improve blood flow in CAD.

How similar studies have gone: Prior IVL approaches have shown safety and feasibility in calcified lesions; this may be the first intravascular lithotripsy feasibility study in this specific setting.
