- W4236891027 abstract "The Bard Atherectomy Catheter is a new rotational atherectomy device that consists of a flexible, hollow, thin-walled cutting catheter that, while rotated at 1,500 revolutions per minute, is advanced across the lesion over a special spiral guidewire system. We report the initial clinical experience with this device in 20 peripheral lesions in ten patients. The majority of patients were treated for limb salvage. All lesions were successfully intervened on by atherectomy followed by adjunctive balloon angioplasty. A reduction to less than 50% stenosis was achieved in 13 of the 20 lesions (65%) after atherectomy but in all 20 lesions (100%) after adjunctive angioplasty for all lesions and stenting for dissections in two. Baseline minimal lesion lumen diameter was 0.8 ± 0.7 mm with a reference vessel diameter of 4.2 ± 1.7 mm (75 ± 21% stenosis). The lumen improved to 2.0 ± 0.8 mm (45 ± 19% stenosis) (P < 0.001) following atherectomy and to 3.9 ± 1.9 mm (13 ± 16% stenosis) (P < 0.001) after adjunctive angioplasty. The average weight of removed atheroma was 45 ± 58 mg. All ten patients had initial improvement in symptoms. At 6 months follow-up there was persistent improvement in eight patients and two subjects had undergone amputations. Our early clinical experience with this low profile, flexible atherectomy device, that enables extraction of a large amount of atheroma, suggests that it will become a valuable addition to current atherectomy technologies in small- and medium-sized vessels. The value of this device in coronary vessels is under investigation. © 1996 Wiley-Liss, Inc." @default.
