Comparative Registry of the PROmus™, ENdeavor™ and CYpher™ Drug Eluting Stents

Boston Scientific is developing the present PROENCY registry to collect real world data with the Promus™ Stent and to compare outcomes to the Cypher™ and Endeavor™ stents.

All three stents have received CE Mark and are commonly used in Europe. All the data collected in this registry will be from patients treated according to the physician's choices, per Product Directions/Instructions for Use, per approved indications and per local standard of care.

The results from this registry will provide an understanding of the use and outcomes associated with the Promus™, the Endeavor™ and the Cypher™ stent systems in a real world setting.

All the data collected in this registry will be from patients treated according to the physician's choices, per Product Directions/Instructions for Use, per approved indications and per local standard of care.

Inclusion criteria

• Per PROMUS or CYPHER or Endeavor DFU/IFU

PROMUS Indications:

• PROMUS™ Everolimus Eluting Coronary Stent System is indicated for improving coronary luminal diameter in patients with symptomatic ischemic heart disease due to discrete de novo native coronary artery lesions (length 28 mm) with a reference vessel diameter of 2.5 mm - 4.0 mm.

CYPHER Indications:

• CYPHER SELECT Sirolimus-eluting Coronary Stent is indicated for improving coronary luminal diameter in patients with symptomatic ischemic disease due to discrete de novo and in-stent restenotic lesions (length 30 mm) in native coronary arteries with a reference vessel diameter of 2.25 mm to 5.00 mm.

Endeavor Indications:

• Endeavor Stent is indicated for improving coronary luminal diameter and reducing restenosis in patients with symptomatic ischemic heart disease in de novo coronary artery lesions in native coronary arteries with a reference vessel diameter of 2.25 mm to 4.0 mm and a lesion length of < 27 mm.

Exclusion criteria

PROMUS Contraindications:

• Patients in whom anti-platelet and / or anti-coagulant therapy is contraindicated.
• Patients judged to have a lesion that prevents complete inflation of an angioplasty balloon.
