What this trial studies

The GISE-SHOCKCALCIUM Registry is a prospective, observational registry aimed at evaluating the efficacy and safety of intravascular lithotripsy (IVL) for treating severe calcified coronary lesions. Conducted across approximately 50 interventional cardiology centers in Italy, the study plans to enroll 2000 patients over 24 months. The primary endpoint is target lesion failure at one year, with secondary endpoints focusing on safety and effectiveness measures. Data will be collected through a structured approach involving screening logs and clinical follow-ups.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with calcified coronary artery disease requiring percutaneous revascularization.

Not a fit: Patients who refuse to participate or do not meet the specific inclusion criteria will not benefit from this study.

Why it matters

Potential benefit: If successful, this registry could improve treatment outcomes for patients with severe calcified coronary lesions.

How similar studies have performed: Other studies have shown promise with similar approaches, but this registry focuses specifically on the use of IVL for calcified lesions, making it a novel initiative.

Inclusion Criteria:

* Patients is ≥ 18 years of age.
* Patients with calcified coronary artery disease requiring percutaneous revascularization with stent implantation who require an IVL with the Shockwave catheter.
