This prospective, multi-center registry will enroll a total of 533 patients. The BioMatrix FlexTM has been studied in randomized controlled trials and has been granted the CE mark. The data have been reviewed by Health Canada and no further randomized trials were requested. Prior to marketing approval, Health Canada requested that a registry be implemented to provide data in Canada on 'on label patients' to supplement the data already available from the Leaders trial, conducted on 'all comers' patients. The registry follows the normal medical practice for drug eluting stents in Canada. 100% informed consents will be checked, and at least all Major Adverse Cardiac Events up to 2 years will be source data verified. All MACEs developing in the patient population will be adjudicated by an independent Clinical Events Committee. The patients will be followed clinically for up to 2 years after stent implantation.
