Probe "balloon on a wire" ultra-low-profile coronary catheter: results of PTCA in 107 patients.

摘要: A new low-profile “balloon-on-a-wire” angioplasty catheter, the Probe™ (USCI), was used in 107 patients over a 4-month period. Twenty-nine had stable angina, 59 unstable and 19 myocardial infarction (Ml) 3 to 15 days prior procedure; 71 single-vessel 36 multi-vessel disease. In this series, 57 lesions were defined as complex. Successful dilatation residual stenosis of <30%. Of 132 non-total obstructions, 127 (97%) successfully dilated. Two distal could not be reached, two crossed by balloon, lesion resulted acute closure one case. Of total 16 (84%) dilated (mean 23%). The wire tip unable cross three unsuccessful procedures. Seven complications occurred all involving obstructions: vessel side branch caused no clinical symptoms or EKG changes; local dissections tacked back with repeat dilatation; longitudinal apparent reduction luminal diameter. The Probe's exceptional trackability enabled it very tight minimal trauma wall. high degree conformability PET balloon minimizes straightening sheer forces appears reduce potential for dissection. device may therefore extend indications ease PTCA while reducing procedure.
