Shockwave IVL for Pre-TAVI

Shockwave Intravascular Lithotripsy (IVL) provides a low-risk, effective way to preserve transfemoral access as a primary option in heavily calcified iliacs in TAVI patients and increases vessel compliance for safer delivery of large devices.

Change Compliance to Change the Game: Shockwave IVL for Transfemoral TAVI & Impella

Prepping for TAVI can prevent the risk of serious complications due to calcium, thanks to the unique mechanism of action (MOA) of Shockwave IVL. In fact, clinical evidence shows: 1–4

  • Shockwave IVL-assisted transfemoral-TAVI is safe and effective 
  • Shockwave IVL is a primary option to preserve transfemoral access  
  • Shockwave IVL increases vessel compliance for safe delivery of large devices

Featured Case: Shockwave IVL Opens Calcified Iliacs to Enable Passage of Transcatheter Aortic Valve Implantation (TAVI) Device

  • Patient background: 78-year-old female with claudication, severely calcified bilateral iliacs   
  • Case goal: Safely modify the calcium in order for vessel compliance to occur and facilitate a TAVI system to be advanced  
  • Why Shockwave IVL: Shockwave’s mechanism of action (MOA) can safely and effectively treat eccentric calcified lesions. Shockwave L6 treats short, focal lesions with a consistent energy profile across the treatment area  
  • Outcome: Shockwave IVL provided effective calcium modification and allowed for desired transfemoral access for TAVI procedure

European Registry: IVL to facilitate transfemoral TAVI

Accordion Section

To report on the safety and efficacy of Shockwave IVL-assisted TF TAVI in an all-comers population. 

  • Prospective, real-world, multi-center registry 
  • All patients treated by Shockwave IVL-assisted TF TAVI ’18 – ’20 
  • 6 high-volume European centers 
  • 108 patients 
  • Target lesion-minimum lumen diameter 4.6 ± 0.9 mm with 318° of calcium 

Procedure Success n (%)
Valve delivery success  108 (100%) 
Valve implantation success  106 (98.2%) 

 

IVL-Related Vascular Complications n (%)
Perforations  1 (0.9%) 
Rupture  0 (0.0%) 
Minor dissection types (types A-C)  4 (3.7%) 
Major dissection types (types D-F)  3 (2.8%) 
Covered stent  2 (1.8%) 
Bare metal stent  3 (2.8%) 

Shockwave IVL has helped expand the indications for TF TAVI in patients with severe calcific peripheral artery disease (PAD).
