title: Use of the frontrunner catheter to cross a chronic total occlusion of the left subclavian artery.
abstract: Crossing a subclavian artery chronic total occlusion may be challenging. We report the treatment of such an occlusion in a patient with a patent left internal mammary graft to the left anterior descending artery, who presented with progressive angina. Several attempts to cross the occlusion, both antegrade and retrograde, with various guidewires failed. The lesion was successfully crossed antegradely using the Frontrunner catheter and was successfully stented with resolution of the patient's angina.
