Glidewire treatment of resistant coronary occlusions.

Inability to cross the site of occlusion with a guidewire is the most common cause of failed angioplasty. The Glidewire, a kink-resistant, flexible wire with a hydrophilic coating, was applied to 71 (59 total, 12 subtotal) refractory occlusions, resulting in an overall angioplasty success rate of 45%. The Glidewire may improve the success rate for PTCA of total and subtotal occlusions that cannot be crossed with conventional guidewires.
