Details and patient eligibility

About

This is a multi centre, prospective trial. 250 patients will be enrolled in the study.(10 patients per centre involving approximately 25 centres). Patients will be followed up clinically for twelve months post-procedure at 1 month, 6 months & 12 months. All patients will have a repeat angiography at 8 months. Clinical follow-up will be maintained for years 3 & 5 post-implant.

Full description

This is a multi centre, prospective observational study. 250 patients will be enrolled in the study. 10 patients per centre involving approximately 25 centres. All the patients will be followed for twelve months post-procedure. All patients will have a repeat angiography assessment at 8 months. An additional clinical follow-up will be maintained for years 3 & 5 post-implant.

Approximately 250 patients with obstructive coronary artery disease with a vessel size between ≥2.5 to ≤3.5 mm in diameter by visual estimate and who meet all eligibility criteria will be treated with the Sirolimus Eluting Stent.

It is anticipated that the total length of the study will be 16 months: 4 months to complete patient enrollment and 12 months for angiographic follow-up.

Enrollment: 250 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers
