Coronary Artery Disease
Conditions
Brief summary
This is a single center, non-randomized study. Patients will be treated with the sirolimus coated Bx VELOCITY Balloon-Expandable Stent mounted on the Raptor OTW SDS. Patients will have a repeat angiography at four months and will be followed for twelve months post-procedure.
Detailed description
This is a single center, non-randomized study of the Bx VELOCITY Balloon-Expandable Stent coated with sirolimus (140µg/cm2) and formulated for fast or slow release. The sirolimus coated stent is mounted on the Raptor OTW SDS. Approximately 30 patients with de novo or restenotic native coronary artery lesions \<=18mm in length and \>=3.0 to \>=3.5 mm in diameter by visual estimate who meet all eligibility criteria will be treated with the sirolimus coated Bx VELOCITY stent(s). Patients will be followed for five years post-procedure and will have a repeat angiography at 4 months, 12 months, 24 months, and 48 months.

Eligibility
Inclusion criteria
1. Diagnosis of angina pectoris as defined by Canadian Cardiovascular Society Classification (CCS) or a positive ischemia study; 2. Single de novo or restenotic lesion requiring treatment in a major native coronary artery; 3. Target lesion is \<=18mm in length (visual estimate); 4. Target lesion is \>=3.0mm and \<=3.5mm in diameter (visual estimate); 5. Target lesion stenosis is \>50% and \<100% (visual estimate);
Exclusion criteria
1. A Q-wave or non-Q-wave myocardial infarction within the preceding 72 hours unless the CK and CK-MB enzymes are back to normal; 2. Unprotected left main coronary disease with \>=50% stenosis; 3. Have an ostial target lesion; 4. Angiographic evidence of thrombus within target lesion; 5. Calcified lesions which cannot be successfully predilated; 6. Ejection fraction \<=30%; 7. Target lesion involves bifurcation (either stenosis of both main vessel and major branch or stenosis of just major branch); 8. Totally occluded vessel;
