Brief Summary:

Significant lesions in small coronary arteries are frequently found (35%-50%) in patients with coronary artery disease. Independently of the type of coronary angioplasty the restenosis and the need for repeat revascularization remains the main limitation, representing a challenging problem even in the DES (drug eluting stent) era. Recently has been developed drug eluting balloons (DEBs), which have been successfully tested in small series on in-stent restenosis, but few evidence is available in the context of small vessels disease.

The current study has been designed to know, in one hand, the clinical efficacy of the Drug elluting balloon IN.PACT FALCON and, in other hand, the effectiveness, and the cost-effectiveness incremental analysis of DEBs (IN.PACT FALCON vs. DES ( RESOLUTE INTEGRITY) in patients with de novo lesions in small vessels.

Detailed Description:
Recent studies have reported the efficacy of the local application of paclitaxel ® inhibiting neointimal proliferation, and thus the limitation of restenosis, which has led to the conception and development of drug-coated balloon or "Drug Eluting Balloons" (DEB), releasing the antiproliferative drug at the time of expansion. Initially they were applied in the treatment of in-stent restenosis. However, DEB may represent a therapeutic alternative in other contexts where anatomo-clinical uses are not always therapeutic percutaneous coronary revascularization with stent implantation, as is the case of coronary lesions located in small vessels.

Drug Information available for: Paclitaxel

Arm Intervention/treatment
Experimental: Drug elluting Balloon (DEB)
Is a coronary dilating device with Paclitaxel ® drug delivery, for dilatation and provisional spot bare metal stenting (BMS).
Device: Drug elluting Balloon (DEB)
Percutaneous transluminal coronary angioplasty with drug elluting ballon and Bare metal stent for rescue.
Other Name: IN.PACT™ Falcon paclitaxel eluting balloon.

Active Comparator: Drug elluting coronary stent (DES)
The Resolute Integrity Zotarolimus-Eluting Coronary Stent System is indicated for improving coronary luminal diameters in patients, including those with diabetes mellitus, with symptomatic ischemic heart disease due to de novo lesions of length ≤ 27 mm in native coronary arteries with reference vessel diameters of 2.25 mm to 4.20 mm.
Device: Drug elluting coronary stent (DES)
Percutaneous transluminal coronary angioplasty (PTCA) with stent
Other Name: Resolute integrity™ zotarolimus drug coronary stent

Primary Outcome Measures :
  1. Compare the clinical efficacy measured by target vessel failure of DEB IN.PACT FALCON DEB versus the resolute integrity stent (DES). [ Time Frame: The efficacy will be evaluated at 1 year. ]
    Target vessel failure (TVF) is define as any revascularization motivated due to myocardial infarction (with or without Q wave) or cardiac death related to the target vessel.

  2. Compare the clinical security measured by the incidence MACE of DEB IN.PACT FALCON DEB versus the resolute integrity stent (DES). [ Time Frame: The security will be evaluated at one month, sixth month and one year ]
    Rate of major adverse cardiac events (MACE) at 30 days, 6 months and one year. MACE was defined as cardiac death, myocardial infarction (MI) (with or without Q-wave), need for repeat revascularization of the treated vessel (surgical or repeat PCI) or occlusion of the treated lesion.

Secondary Outcome Measures :
  1. Compare the efficiency of DEBs versus DES. in terms of cost effectiveness (cost per adverse event-death avoided) and cost-utility ( cost per quality adjusted life year) in patients with de novo lesions in small vessels. [ Time Frame: The efficiency will be evaluated at first month, 6 month and 1 year. ]
    In order to perform a cost-utility analysis, years of quality-adjusted life (QALY) gained will be measured using the quality of life questionnaire EuroQoL five dimensions (EQ-5D) and a visual scale at baseline, one month and 12 months.

  2. Compare the direct cost, indirect costs and total costs of DEBs versus DES in patients with de novo lesions in small vessels. [ Time Frame: This outcome will be evaluated at first month, 6 month and 1 year. ]
