No-profit, Pilot, Observational, Multicentric, Prospective Study on the Use of Shockwave M5+ IVL Catheter (Intravascular Lithotripsy) in Hostile and Calcified Iliac Access to Facilitate Aortic Endovascular Repair. SHOCK-ACCESS STUDY.
The study will evaluate, in a controlled setting, the efficacy and safety of the intravascular lithotripsy using Shockwave™ M5+ Peripheral Intravascular Lithotripsy Catheter to facilitate delivery of aortic large-bore devices in iliac calcified access.
• Age ≥18 years old;
• Patient (or their legal representative) understands the nature of the procedure and provides written informed consent, prior to enrolment in the study;
• Patient presenting with aortic disease indicated for endovascular treatment considered unfeasible based on severely calcified iliac access and outer diameter of the ideal aortic endograft at onset of the procedure (considering the main body and/or contralateral limb in case of iliac distal landing zone);
• Patients presenting a ratio \> 0.2 between outer diameter of the aortic stent graft delivery system (OD-SG) and minimum lumen diameter (MLD); decision concerning SG will be taken balancing the lower profile on the market and the better graft fit for patient's anatomy;
• Patients presenting calcium grade 3 or 4 accordingly to 360° coronary classification (grade 1 = 0-90°, grade 2 = 90°-180°; grade 3 = 180°-270°; grade 4 = 270°-360°);
• Patients presenting a lesion length \> 20 mm, intended as the sum of all calcified iliac lesions between two endpoints, from the aortic bifurcation up to the proximal common femoral artery (CFA);
• Patients eligible for treatment with Shockwave M5+ IVL device;
• Patients presenting with aortic disease indicated for endovascular treatment associated or not to aorto-iliac occlusive disease (Rutherford classification score II - VI for chronic limb ischemia);
• Patients compliant with the conduct of follow-up visits according to the timelines specified in the protocol.
