title: Guidewire-induced coronary pseudostenosis as a source of error during physiological guidance of stent deployment.
abstract: Coronary pseudostenoses are a known result of the interaction between tortuous vessels and guidewires and are generally handled by the interventionalist as inocuous side effects of intracoronary instrumentation. The present report demonstrates that pseudostenosis may have hemodynamic relevance and may constitute an important source of error when physiological guidance of percutaneous procedures is performed using sensor-tipped guidewires.
