Study summary

The aim of this prospective randomised study is to compare the safety and efficacy of novel intravascular lithotripsy (IVL) to the standard therapy of calcified coronary lesions.

Read the detailed description

The study will include a total of 40 patients with calcified coronary lesions who will be randomised 1:1 to the treatment with IVL (Shockwave; Shockwave Medical, Inc, Santa Clara, USA) or the standard therapy (non-compliat high-pressure or Scoreflex predilatation, rotational atherectomy, etc). Appropriate preparation of the lesions will be followed by DES implantation.

Study arms

  • Experimental
    Intrvascular Lithotripsy

    Calcified coronary lesions will be treated with intrvascular lithotripsy

    Device: Intravascular lithotripsy

  • Active comparator
    Standard therapy

    Standard treatment of calcified coronary lesions: cutting, scoring or non-compliant balloon predilatation or rotational atherectomy

    Device: Standart therapy

Interventions

  • DeviceIntravascular lithotripsy

    Intravascular lithotripsy uses sonic pressure waves to disrupt calcium with minimal impact to soft tissue of coronary vessel

  • DeviceStandart therapy

    conventional preparation of calcified lesion: non-compliant, cutting or scoring ballons predilatation or rotational atherectomy

What researchers measure

Primary outcomes

  1. Minimal lumen diamether (MLD)

    minimal diamether of treated lesion measured by quantitative coronary angiography

    Time frame: 1 year

  2. Late luemn loss (LLL)

    difference between post-procedure MLD and 12-month MLD

    Time frame: 1 year

Secondary outcomes

  1. Binary in-stent restenosis

    diamether stenosis ≥ 50% of reference vessel

    Time frame: 1 year

  2. Major adverse cardiac events (MACE)

    Cardiac death, myocardial infarction or tagret lesion revascularisation (TVR)

    Time frame: 1 year

Other outcomes

  1. Angiographic success

    success in facilitating stent delivery with \<50% residual stenosis and without serious angiographic complications

    Time frame: up to end of the procedure, an average of 2 hours

  2. Clinical success

    angiographic success with no evidence of in-hospital MACE

    Time frame: up to discharge, an average of 3 days
