Area of Science:

  • Cardiovascular Interventions
  • Medical Device Technology

Background:

  • Transcatheter aortic valve replacement (TAVR) is a crucial procedure for severe aortic stenosis.
  • Current TAVR support wires lack integrated hemodynamic monitoring capabilities.

Purpose of the Study:

  • To evaluate the safety, efficacy, and functionality of the SavvyWire support wire during TAVR.
  • To assess the SavvyWire's ability to provide live transvalvular hemodynamic data and left ventricular (LV) pacing.

Main Methods:

  • A prospective, observational, single-arm registry involving 60 patients undergoing TAVR across 3 Canadian centers.
  • Data collection included procedural outcomes and post-procedure questionnaires from implanters.

Main Results:

  • The SavvyWire demonstrated a 100% success rate for TAVR system delivery and 98% for effective LV pacing.
  • No instances of LV perforation, guidewire deformation, or significant pacing issues were reported.
  • 97% of procedures found SavvyWire functionality to be superior or comparable to existing TAVR wires.

Conclusions:

  • SavvyWire is a safe, effective, and functional tool for TAVR, enabling real-time hemodynamic assessment and pacing.
  • Further research with larger cohorts and comparative analyses is recommended to solidify its role in TAVR procedures.
