New Valve Technology Program for Transcatheter Aortic Valve Implantation

Among new-generation devices for transcatheter aortic valve implantation (TAVI), the Allegra device, developed by New Valve Technology, represents an interesting adjunct to the interventionalist’s armamentarium. In particular, this self-expandable device consists of a nitinol metallic frame with bovine pericardium leaflets, boasting also dedicated gold markers for optimal positioning and a 12-mm sealing area to minimize paravalvular leak. It is available in 23 mm, 27 mm, and 31 mm sizes, suitable for annuluses ranging from 19 mm to 28 mm in diameter. Its low invasiveness (18 French cartridge/15 French shaft which ensure compatibility with a 13.5 French balloon expandable introducer sheath) and controlled-release features make this a promising device for TAVI.
