TRAns-Femoral Access Intravascular Lithotripsy Comparison With PTA in TAVI
To compare the effectiveness and the safety of femoral-iliac IVL versus balloon only PTA for successful deployment of transfemoral transcatheter aortic valve prosthesis.
• Age \> 18 years
• Written informed consent
• Diagnosis of symptomatic severe aortic stenosis
• Patient undergoing TAVI according to local institutional protocol and following Heart Team discussion.
• High-quality Contrast-enhanced ECG gated computed tomography (CT) scan of the heart, aorta and low-limb arteries
• Calcific severe PAD raising concerns within the Heart Team and judged as arguable for TF approach following angiography or CT-scan evaluation (hostile femoral access), with a RefD\>/=5 mm and a MLD\>/=3 mm.
• Hostility score \>/= 23 in at least one segment of the axis under evaluation.
