Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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 Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intrvascular Lithotripsy

Calcified coronary lesions will be treated with intrvascular lithotripsy

Group Type EXPERIMENTAL

Intravascular lithotripsy

Intervention Type DEVICE

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

Standard therapy

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

Group Type ACTIVE_COMPARATOR

Standart therapy

Intervention Type DEVICE

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