Abstract

In a randomized multicenter study initial success rate and 6 months' follow-up were compared between coronary angioplasty performed with the Barath Cutting Balloon (group A, n = 32) and conventional balloons (group B, n = 32) in patients with type A or B lesions in native coronary arteries. The culprit lesion was not reached in one patient in group A. Initial success rates were similar with and without additional stenting (8 in group A and 10 in group B). Angiographic follow-up data (in 95%) revealed a non-significant improvement in minimal lumen diameter, diameter stenosis in group A. Restenosis developed in 16.7% of group A vs 25.8% of group B, (p = 0.57). A separate analysis of stented patients showed no restenosis in group A and restenosis in 4 out of 10 patients in group B (p = 0.10). A possible beneficial effect of the Cutting Balloon with respect to in-stent restenosis requires further studies. [ABSTRACT FROM AUTHOR]

Abstract

OBJECTIVESThe purpose of this study was to assess the clinical and angiographic benefits of elective stenting in coronary arteries with a reference diameter of 2.1 to 3.0 mm, as compared with traditional percutaneous transluminal coronary angioplasty (PTCA).BACKGROUNDThe problems related to small-vessel stenting might be overcome using modern stents designed for small vessels, combined with effective antiplatelet therapy.METHODSIn five centers, 145 patients with stable or unstable angina were randomly assigned to elective stenting treatment with the heparin (Hepamed)-coated beStent or PTCA. Control angiography was performed after six months. The primary end point was the minimal lumen diameter (MLD) at follow-up. Secondary end points were the restenosis rate, event-free survival and angina status.RESULTSAt follow-up, there was a trend toward a larger MLD in the stent group (1.69 ± 0.52 mm vs. 1.57 ± 0.44 mm, p = 0.096). Event-free survival at follow-up was significantly higher in the stent group: 90.5% vs. 76.1% (p = 0.016). The restenosis rate was low in both groups (9.7% and 18.8% in the stent and PTCA groups, respectively; p = 0.15). Analyzed as treated, both the MLD and restenosis rate were significantly improved in patients who had stents as compared with PTCA.CONCLUSIONSIn small coronary arteries, both PTCA and elective stenting are associated with good clinical and angiographic outcomes after six months. Compared with PTCA, elective treatment with the heparin-coated beStent improves the clinical outcome; however, there was only a nonsignificant trend toward angiographic improvement.
