Improved Outcomes With Pre-Procedure Shockwave IVL of Common Femoral Artery Access Site Prior to Large Bore Access and Pre-Closure
University of Tennessee Graduate School of Medicine
Summary
The primary purpose of this study is to observe reduced access site complications in patients with heavily calcified common femoral arteries requiring Transcatheter Aortic Valve Replacement (TAVR)
Description
This is a prospective randomized/control trial pilot study to compare clinical outcomes of common femoral artery access in patients undergoing TAVR at the University of Tennessee Medical. Specifically, This study compares patients utilizing the Shockwave model (M5) Intravascular Lithotripsy (IVL) prior to standard arterial access using the modified Seldinger technique to those utilizing the standard femoral artery access via the modified Seldinger approach without the utilization of intravascular lithotripsy in heavily calcified femoral arteries. The secondary purposes of this study are to:…

Interventions
- DeviceShockwave M5 IVL Catheter
The Shockwave M5 IVL Catheter is a balloon catheter designed to modify calcified arterial plaque using intravascular lithotripsy prior to vascular access
- ProcedureModified Seldinger Technique
Standard of care for femoral access in patients with calcified femoral arteries
- ProcedureModified Seldinger Technique
Standard femoral artery access using the modified Seldinger technique without any prior vessel preparation or plaque modification.
