A Prospective, Multicenter, Real-World Registry of Coronary Lithotripsy in Calcified Coronary Arteries: The REPLICA-EPIC18 Study
Authors' conclusion
Coronary IVL proved to be a feasible and safe procedure in a "real-life" setting, effectively facilitating stent implantation in severely calcified lesions. Patients with ACS on admission showed similar angiographic success rates but showed a trend toward higher 30-day MACE compared with patients with CCS.
Study context
- Population
- Consecutive all-comer patients with calcified coronary lesions treated with intravascular lithotripsy (IVL), 26 centres in Spain
- Participants
- 426 patients · 456 lesions
- Exposure
- Acute coronary syndrome (ACS) vs chronic coronary syndrome (CCS) in patients treated with coronary IVL
- Outcome
- Procedural success (successful IVL delivery, final diameter stenosis <20%, no in-hospital MACE)
Methodological detailsmulticentre, consecutive patients, independent core laboratory, 26 centres in Spain, predefined substudy ACS vs CCS
- Multicentre

- Lesions considered undilatable before IVL
- 49%
Angiographic success after IVL
- No significant differences between CCS and ACS
Safety
MACE (primary safety endpoint) · 30 days
P = 0.073
- MACE (primary safety endpoint) — MACE at 30 days, all patients
- 3%
