About this trial
Coronary artery disease is caused by narrowing of the artery lumen. Treatment with Percutaneous Coronary Intervention (PCI) may be needed. This is a minimally invasive procedure used to treat narrowed or blocked coronary arteries. Sometimes a stent is placed to keep the artery open. If the lesions in the coronary artery are calcified, this may cause difficulties for successful stent placement. The calcified plaques can be fractured via intravascular lithotripsy (IVL) with devices like ShockWave IVL and ShockFast IVL. The aim of this study is to compare the this relatively new ShockFast IVl with the more widely used ShockWave IVL.
