Coronary Restenosis
Conditions
Brief summary
Treatment of coronary in-stent restenosis (ISR) by a sirolimus coated SEQUENT® SCB RAPID EXCHANGE PTCA balloon catheter or a paclitaxel coated SEQUENT® PLEASE PTCA balloon catheter
Detailed description
Experimental intervention: Predilatation of coronary ISR with POBA followed by a sirolimus coated SeQuent®SCB balloon balloon (sirolimus 4.0 μg/mm²) Control intervention: Predilatation of coronary ISR with POBA followed by a paclitaxel coated SeQuent®Please balloon or SeQuent®Please NEO balloon (paclitaxel 3.0 μg/mm²) Duration of intervention per patient: minutes Follow-up per patient: 30 days telephone call; 6 months angiographic + 12 months clinical follow up
Interventions
Predilatation of coronary ISR with POBA (balloon-to-stent ratio 1:1) followed by a sirolimus coated balloon (SeQuent®SCB balloon with sirolimus 4.0 μg/mm²)
Predilatation of coronary ISR with POBA (balloon-to-stent ratio 1:1) followed by a paclitaxel coated balloon (SeQuent®Please balloon or SeQuent®Please NEO balloon with paclitaxel 3.0 μg/mm²) (paclitaxel 3.0 μg/mm²)

Eligibility
Inclusion criteria
* 18 years of age * Clinical evidence of stable or unstable angina (acute coronary syndrome) or a positive functional study * Patients with ≤ 2 primary in-stent restenosis (ISR) lesions (≥ 70% diameter stenosis by visual estimation or ≥50% and positive functional study) including margin-stenosis with max 5 mm distance to the stent
Exclusion criteria
* Chronic renal insufficiency with serum creatinine levels \> 2.0 mg per deciliter * Known hypersensitivity or contraindications to aspirin, heparin, clopidogrel, ticlopidine or sirolimus, and sensitivity to contrast media not amenable to premedication * Concomitant medical illness associated with a life-expectancy of less than two year * Lesion length (ISR) \> 35 mm, reference vessel diameter \< 2.5 mm
