The novel Undermining iatrogenic coronary obstruction with radiofrequency needle (UNICORN) technique modifies native valves to prevent coronary obstruction during transcatheter aortic valve replacement (TAVR). This electrosurgical method preserves coronary access when bulky calcification is present.

Area of Science:

  • Cardiovascular Surgery
  • Interventional Cardiology
  • Medical Devices

Background:

  • Transcatheter aortic valve replacement (TAVR) carries a risk of life-threatening coronary obstruction from displaced calcified native valve leaflets.
  • Preventing coronary obstruction is crucial for TAVR success, especially in valve-in-valve procedures.
