Crossing Chronic Total Occlusions
Wires to be used in escalating order of aggressiveness:
First Choice
Non-hydrophilic or hydrophobic wires with an intermediate stiffness are a good first choice as they have a better tactile response, are less likely to lead to a subintimal position than a hydrophilic wire, and may have an additional advantage in their ability to cross the proximal cap of the occlusion. Choices in this class include the Miracle Bros 3 and the Asahi intermediate wires.
Second Choice
Hydrophilic wires may track better after the proximal cap of the occlusion has been crossed. Hydrophilic/coated wires have better maneuverability in tortuous or calcified vessels. Intermediate stiffness hydrophilic wire choices include the Choice PT XS (Extra Support), the Pilot 50, the Pilot 100 or the PT Graphix intermediate wire.
Third Choice
Stiff non-hydrophilic wires: The Miracle Bros 6, 9 and 12, Cross-IT, Confienza, Persuader
Fourth CHoice
Stiff and hydrophilic (most aggressive): Pilot 200 and Shinobi
