Key Findings

CAD III confirms Shockwave IVL safety with low rates of major peri-procedural clinical and angiographic complications, setting a new bar for safety in complex calcified coronary lesions. 

  • 92.2% of patients were free from major adverse cardiovascular events (MACE) at 30 days, a composite of cardiac death (CD) (0.5%), myocardial infarction (MI) (7.3%), or target vessel revascularization (TVR) (1.6%)  
  • Primary MACE driver was in-hospital non-Q-wave MI (5.7%) 
  • Low risk of perforation (0.3%), major dissection (0.3%), abrupt closure (0.3%) and slow flow/no reflow (0.0%) at the end of procedure 

CAD III showcases Shockwave IVL effectiveness with large lumen gains that facilitate stent delivery and optimize stent expansion. 

  • 92.4% procedural success rate, defined as successful stent delivery (99%) residual stenosis <50% (100%) and without in-hospital MACE (93%) 
  • Successful Shockwave IVL crossing and therapy delivery in 98% of lesions, correlating to 99% stent delivery 
  • 1.7 mm acute gain and 11.9% final in-stent residual stenosis 

CAD III demonstrated Shockwave coronary IVL’s ease of use and quick learning curve to achieve consistently predictable outcomes. 

  • MACE, procedural success and device crossing success were similar between roll-in procedures (first case for each site) and procedures included in the pivotal analysis (taken from the DISRUPT CAD III publication)

Study Design and Patient Characteristics
