Summary
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.
