An observational study of Iliac Disease and Aortic Valve Stenosis, run by Baylor Research Institute at 1 site in United States.
Trial summary
To assess the efficacy and safety of Intravascular Lithotripsy (IVL) in subjects undergoing transfemoral TAVR in patients with severe iliac disease, prohibitive for transfemoral TAVR in patients with severe symptomatic aortic stenosis, otherwise considered for alternative access TAVR. (e.g. trans-carotid) Read more about this study

About this study
To assess the efficacy and safety of Intravascular Lithotripsy (IVL) in subjects undergoing transfemoral TAVR in patients with severe iliac disease, prohibitive for transfemoral TAVR in patients with severe symptomatic aortic stenosis, otherwise considered for alternative access TAVR. (e.g. trans-carotid)
Read the detailed description
The goal of this post-market, prospective, observational single-arm cohort study is to assess the efficacy and safety of Intravascular Lithotripsy (IVL) in subjects undergoing transfemoral TAVR in patients with severe iliac disease, prohibitive for transfemoral TAVR in patients with severe symptomatic aortic stenosis, otherwise considered for alternative access TAVR. (e.g. trans-carotid). This is a study of patients referred to BSW The Heart Hospital, Plano for evaluation of critical aortic stenosis. Those planned to undergo TAVR, have prohibitive iliofemoral disease, and otherwise considered for alternative access, will be considered for the study. The medical devices being used are in the post-market stage as it is being used in accordance with its approved labeling, treating iliofemoral disease.
Study data will be recorded prospectively on dedicated Data Collection Forms and stored locally in a secure format. De-identified data will be uploaded for statistical analysis. IRB approval for the study will be obtained.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Shockwave BalloonDevice
Intravascular lithotripsy (IVL) performed with the Shockwave balloon (Shockwave Medical Inc) enables treatment of calcified stenosis of the peripheral arteries by using sonic pressure waves to selectively disrupt superficial and deep calcium without impacting healthy tissue
What is being measured
The primary outcome is the main question the study is designed to answer.
Acute technical success per the DISRUPT PAD definition at the time of intervention
Defined as final residual stenosis ≤30% without flow-limiting dissection (≥ Grade D) of the lesion
Measured: At time of IVL procedure
Success rate of transfemoral delivery of a TAVR system post IVL within 30 days of treatment
To know the efficacy of the treatment
Measured: At the time of TAVR procedure
Secondary outcomes (2)
Applicable VARC-3 criteria at the time of peripheral intervention for bleeding, access site and access related complications.
To understand the efficacy of the treatment
Measured: At IVL procedure
Major adverse events within 1 year
need for emergency surgical revascularization of target limb, unplanned target limb major amputation (above the ankle), symptomatic thrombus or distal emboli that requires surgical, mechanical, or pharmacologic means to improve flow and extend hospitalization, perforations that require an intervention, including bail-out stenting.
Measured: 1 year after IVL procedure
