A variety of Guidewires in diameters ranging from 0.014 to 0.035 inch and lengths ranging from 50 to 260 cm is also required. They should be of the super floppy, ordinary, super stiff, and glide wire (e.g., Terumo) types. Amplatz extremely firm and ultra-stiff guide wires (0.025 to 0.038 inch) (Cook Medical, Bloomington, IN, USA) are a mainstay for practically every case and are important for stabilising balloons over high flow lesions and during stent insertion or valvuloplasty. The Meier Backup wire (Boston Scientific, Natick, MA, USA) has proven to be an extremely useful instrument for transcatheter pulmonary valve implantation.

The diameter and length of Guidewires range from 0.014 to 0.038 inches and 50 to 260 cm, respectively. Their construction includes wire cores with variable degrees of tensile strength and outside coatings with varying hydrophilic and lubricious properties. The wire's distal 1 to 5 cm end is generally distinct in design and manoeuvrability from the rest of its length; this end frequently determines a wire's usability.
