title: Relief of pseudostenosis using the transit exchange catheter.
abstract: Pseudostenosis is a generally benign complication of percutaneous coronary intervention that is caused by the mechanical deformation of a tortuous artery by the guidewire. We describe two cases of a tortuous right coronary artery in which pseudostenosis was relieved by placing a Transit exchange catheter (Cordis) distally and subsequently removing the guidewire. This technique safely confirmed the diagnosis of pseudostenosis without losing guidewire position or requiring additional wires and balloons.
