The UNICORN technique simplifies leaflet modification during transcatheter aortic valve replacement (TAVR) to prevent coronary obstruction. This radiofrequency-based approach offers advantages over existing methods for TAVR procedures.

Area of Science:

  • Cardiology
  • Interventional Cardiology
  • Medical Devices

Background:

  • Transcatheter aortic valve replacement (TAVR) is a common procedure for aortic stenosis.
  • Coronary obstruction is a potential complication during TAVR, especially in valve-in-valve cases.
  • Existing methods for preventing coronary obstruction, like BASILICA, have limitations.
