Long balloon angioplasty with focal stenting for the treatment of diffuse coronary artery disease.
The objective of this study was to evaluate the efficacy of treating long coronary lesions (> 30 mm) with either a 40 or a 60 mm long Scimed Cobra balloon followed by focal (contingency) stenting of areas with suboptimal results. Diffuse lesion length is a morphological characteristic associated with a poorer clinical outcome after balloon angioplasty with or without stenting. Patients were enrolled in a prospective randomized fashion to have initial PTCA with either a 40 or a 60 mm long balloon followed by focal stenting in areas with suboptimal results. The MACE rate at 6-month follow-up was collected from all patients and was the primary endpoint of the study. A total of 41 patients were enrolled into the study. The acute procedural success rate was 97.5% with a 6-month MACE rate of 9.8%. The use of long balloons with contingency stenting is a highly effective strategy for the treatment of diffuse coronary lesions.
