The utility of a jailed pressure wire technique for the treatment of coronary bifurcation lesion in a patient with chronic kidney disease.

A 56-year-old male was admitted to our hospital complaining of chest pain. The patient had chronic kidney disease requiring a minimum contrast procedure when performing percutaneous coronary intervention. A jailed wire technique is known to reduce the risk of side branch occlusion. We report a case measuring the presence of ischemia in the side branch (SB) by a jailed Opto Wire (Opsens, Quebec) after implantation of a stent in the main vessel for the treatment of a bifurcation lesion. This method provides for a decrease in usage of contrast without leaving the side branch at risk of ischemia.
