Study Arms (2)

Intravascular Lithotripsy

EXPERIMENTAL

Study Device Treatment: IVL balloon catheter size is chosen in a 1:1 ratio to the distal reference vessel diameter. If the IVL balloon cannot be delivered into the target lesion a Guide catheter extension is recommended. The balloon catheter is then inflated to 4 ATM and 10 impulses are delivered. The balloon is then inflated to 6 ATM and deflated to reestablish blood flow. Up to 80 impulses can subsequently be delivered and the balloon can be repositioned within the lesion. In multiple lesions with different reference vessel diameters different sizes of IVL balloon can be used.

Device: Intravascular Lithotripsy

Rotational Atherectomy

ACTIVE COMPARATOR

Control group treatment: Rotablation should be performed as described in the ESC-Consensus document. Burr/vessel-ratio is 0.5 - 0.75. The use of different burr sizes as well as the use of a temporary pacemaker is left to the operator's discretion.

Device: Intravascular Lithotripsy

Interventions

Coronary Angiography. When the anatomic inclusion criteria are met, traverse the lesion with a guidewire. If traversal fails, assign the subject to the registry. After wire traversal has been documented by cine angiography, angiographic, OCT-defined or balloon expansion criteria are met, subject is enrolled. Blood sample for Troponin (hs TnT) baseline measurement has to be taken. The subjects will be randomized in a 1:1 fashion to treatment with either IVL or RA.
