Coronary calcified lesions will have an increasing impact in the daily practice of coronary angioplasty, considering the epidemiological explosion of factors favoring coronary calcifications, first of all diabetes. Moreover, calcified lesions are underestimated in angiography and associated with an increase in angiographic complications, as well as with a worse clinical prognosis. The usual techniques for the preparation of calcified plaque, in particular rotary atherectomy, have a low penetration rate in France (3% of procedures) and are associated with an increase in per-procedural complications without clinical evidence of effectiveness4. A new device has been developed by Schockwave Medical Inc. for the treatment of calcified lesions to facilitate stent delivery: the C2 Shockwave Medical Coronary Lithotripsy System (IVL), Inc. This system uses the principle of lithotripsy to induce microfractures in the calcified plaque prior to low-pressure balloon dilatation. The objective of the study is to evaluate the safety and performance of the C2 Shockwave Medical (IVL), Inc. coronary lithotripsy system in coronary angioplasty in the general population in France.
