What this Trial Is About

ICECAP is a multi-centre, prospective, single-arm, interventional, traditional feasibility clinical investigation to evaluate the efficacy and safety of intra-coronary cryotherapy on vulnerable or high-risk plaque (HRP), using the CryoTherapy System (CTS). The study aims to enroll 25 patients with symptomatic coronary artery disease, successfully treated for their culprit lesion and with presence of at least one HRP lesion in another vessel. Eligible patients will undergo cryotherapy during a planned procedure. Near-infrared spectrometry (NIRS and Optical Coherence Tomography imaging will be used during baseline procedure, and during a 9 months follow visit. The primary endpoint is reduction of plaque burden measured as 30% reduction in maxLCBI4mm as measured by NIRS at 9 months post procedure.

Eligibility Criteria

Eligible

You may qualify if you...

  • Non-ST-segment elevation myocardial infarction with elevated cardiac enzymes requiring PCI within 72 hours
  • Unstable angina
  • ST-segment elevation myocardial infarction
  • Successful PCI of the culprit lesion with less than 30% diameter stenosis and TIMI 3 flow without complications
  • Presence of at least one high-risk plaque in a non-culprit vessel confirmed by imaging with specific features
