A prospective study on percutaneous coronary angioscopy with different guiding techniques in patients with coronary
Abstract:
The technical success of percutaneous coronary angioscopy using different guiding techniques was evaluated in 17 patients before (n = 17) and after (n = 8) coronary angioplasty. Steering the angioscope along or over a guidewire was successful in both groups; failures were predominantly due to insufficient alignment of the angioscope using along-the-wire guiding. Although over-the-wire angioscopy promises superior guiding and alignment capabilities, several technical problems remain unsolved.
