Overview

A pseudolesion is a stenosis that appears in an artery after the coronary gidewire is placed in the artery.

Risk Factors

Pseudolesions appear in tortuous sections of vessels that have been straightened out by the guidewire.

Differential Diagnosis

A pseudolesion must be distinguished from a dissection or coronary spasm.

Diagnosis

A pseudolesion will usually disappear if the wire is withdrawn to the distal edge of the lesion. A pseudolesion should completely disappear after the wire is withdrawn from the coronary artery.

Treatment

Pseudolesions should not be stented or dilated!

Complications

Inadvertent stenting of pseudolesions by overzealous interventional cardiologists.
