Key result
Use of a polymer-jacketed guidewire successfully restored antegrade flow and resolved ST-segment elevation following inadvertent subintimal stenting during PCI of a right coronary artery CTO.
Case Report (n=1)
A polymer-jacketed guidewire can be used to restore antegrade flow and resolve ischemia after inadvertent subintimal stenting during CTO PCI.
May offer bailout option after subintimal stenting in CTO PCI; hypothesis-generating and requires prospective validation.
We present a case of percutaneous coronary intervention of a chronic total occlusion of the right coronary artery. The lesion could not be crossed with a balloon after guidewire crossing, necessitating repeat crossing using a different pathway. Stent implantation resulted in ST-segment elevation due to inadvertent stent deployment into the subintimal space without distal outflow. A polymer-jacketed guidewire was used to enter the distal branches of the right coronary artery, restoring antegrade flow and resulting in resolution of ST-segment changes.

Patel et al. (2013) conducted a case report in Chronic total occlusion of the right coronary artery (n=1). Polymer-jacketed guidewire to enter distal branches was evaluated on Restoration of antegrade flow and resolution of ST-segment changes. Use of a polymer-jacketed guidewire successfully restored antegrade flow and resolved ST-segment elevation following inadvertent subintimal stenting during PCI of a right coronary artery CTO.
