Workhorse guidewires typically have soft tips, but the amount of shaft support varies (Table 5.5 ). Although some wires have preshaped tips, the tip stiffness can be increased by heating it during the preshaping process and the standard (30 degrees, 2‐3 mm from the tip) angle may not match the anatomy. As a result, preshaping rarely offers
