"Initial Experience and Bench Validation of the CLEVE Prosthetic Leaflet Modification Procedure..." (2024/2025).

In cardiology, refers to a specific electrosurgical technique used during heart valve replacements.

Standing for CLE veland V alve E lectrosurgery, this method uses a catheter-based electric current to cut or "lacerate" biological valve leaflets.
