Summary

Calcified coronary lesions are increasingly common in percutaneous coronary intervention. Intravascular lithotripsy offers a safe and effective method for preparing these challenging lesions before stent implantation.

Area of Science:

  • Interventional Cardiology
  • Cardiovascular Devices
  • Biomedical Engineering

Context:

  • Increasing prevalence of calcified coronary lesions in daily percutaneous coronary intervention (PCI) practice.
  • Calcified lesions are a key factor in High-Risk Percutaneous Coronary Intervention (CHIP).
  • Optimal stent expansion and apposition are crucial for successful short- and long-term PCI outcomes.

Purpose:

  • To review the mechanism of action of intravascular lithotripsy for coronary plaque preparation.
  • To outline optimal usage conditions for the Shockwave Medical C2 device.
  • To synthesize recent literature data on intravascular lithotripsy in calcified coronary lesions.

Summary:

  • The C2 Shockwave Medical catheter, CE-marked since 2017, utilizes intravascular lithotripsy to prepare calcified coronary lesions before stenting.
  • This system is noted for its ease of use and high procedural safety.
  • It presents a viable alternative to conventional plaque preparation techniques.

Impact:

  • Facilitates improved stent expansion and apposition in calcified lesions.
  • Enhances procedural success rates for complex PCI cases.
  • Offers a potentially safer and more effective approach for managing challenging coronary artery disease.
