Following randomization to FD or BST, patients will undergo the assigned intervention and be followed for 12 months. Clinical status will be recorded at discharge, at 1-3 months, and at 3-12 months. Angiographic evaluation will be recorded at 3-12 months. Adverse Events will be recorded immediately after the procedure and during the 12-month follow-up period. Patients in the FD registry will similarly be followed for 12 months. A total of 344 patients will be recruited in 20 centers worldwide. The trial is expected to last for 5 years.
