title: Technique for guiding catheter exchange during coronary angioplasty while maintaining guidewire access across a coronary stenosis.
abstract: This case report describes a technique for guiding catheter exchange while angioplasty extended guidewire access is maintained across a coronary artery stenosis with a 245-cm-0.035-in.-long wire in the aorta to exchange for a more favorable guiding catheter. The indications, technique, and outcome of a case are described; it illustrates the usefulness of maintaining angioplasty guidewire access in a difficult-to-cross coronary stenosis.
