Combined Paclitaxel‐Eluting Balloon and Genous Cobalt–Chromium Alloy Stent Utilization in De Novo Coronary Stenoses (PEGASUS)
2013
Objectives
The aim of this study was to examine the angiographic result and its outcome predictors using the combination of paclitaxel-eluting balloon (PEB) and Genous stent.
Background
This approach to treat coronary stenoses is a logical strategy to strike a balance between minimizing restenosis and stent thrombosis.
Methods
From November 2010 to June 2012, 40 symptomatic patients with 44 de novo coronary lesions of diameter stenosis ≥50% were treated with the combination of PEB and Genous stents. Angiographic and clinical follow-up were intended at 6 and 9 months, respectively.
Results
The mean age of patients was 61 ± 11 years, with male predominance (83%). Diabetes mellitus and end-stage renal failure on peritoneal dialysis were found in 15 (38%) and 10 (25%) patients, respectively. Patients received dual antiplatelet therapy for 5.1 ± 1.5 months post procedure. The size and length of PEB used was larger than the stents (3.13 ± 0.46 mm and 28 ± 9 mm vs. 2.98 ± 0.36 mm and 23 ± 7 mm). Restudy angiography was performed on 41 (95%) lesions in 37 (93%) patients at 5.9 ± 1.7 months. Angiographic restenosis was seen in 5 (12%) lesions, and significantly associated with diabetes mellitus and dialysis dependency; the late lumen loss was 0.38 ± 0.37 mm. At 9-month follow-up, no stent thrombosis was observed.
Conclusions
The use of PEB combined with Genous stent is associated with a reasonably low restenosis and late lumen loss, whereas diabetes mellitus and renal failure with dialysis are poor predictors of angiographic restenosis.
