Title: A Prospective Randomized Comparison of the BioFreedom Biolimus A9 Drug Coated Stent Versus the Gazelle Bare Metal Stent in Patients With High Risk of Bleeding.
Brief Summary: The purpose of this study is to demonstrate that a BioFreedom™ Drug Coated Stent is non-inferior to a bare metal stent at one year as measured by the composite safety endpoint of cardiovascular death, myocardial infarction and definite/probable stent thrombosis, and that its efficacy is superior to a bare metal stent as measured by clinically driven TLR at one year.


Options:
A: Inclusion Criteria:

* Patients must have documented atrial fibrillation on 2 separate occasions within 6 months before screening
* History of a prior stroke, transient ischemic attack or non-neurologic systemic embolism believed to be cardiac in origin, or at least two of the following risk factors: heart failure, hypertension, age 75 years or greater, diabetes mellitus

Exclusion Criteria:

* Significant mitral stenosis
* Transient atrial fibrillation caused by a reversible disorder
* Active internal bleeding
* Severe disabling stroke
* History of intracranial bleeding
* Hemorrhagic disorders
B: Inclusion Criteria:

* 21 years of age or older; male or female.

* A moderate to high risk of stroke, as defined by CHADS2 index score of at least 2

Exclusion Criteria:

* Transient atrial fibrillation secondary to other reversible disorders
* Subjects with moderate or severe mitral stenosis, unresected atrial myxoma, or a mechanical heart valve
* Subjects with any contraindication for anticoagulant agents;
* Subjects with conditions associated with high risk of bleeding or have known or suspected hereditary or acquired bleeding disorders
* Females of childbearing potential including the following:

  * Females with a history of tubal-ligation
  * Females less than 2 years post-menopausal
C: Inclusion Criteria:

* Patients is on oral anticoagulation therapy and this will be continued throughout the period of 1 year-and deployment of at least 1 coronary stent (bare metal stent (BMS) or drug eluting stent (DES)). -age of more than 18 years

Exclusion Criteria:

* age \> 80 years
D: Inclusion Criteria:

* Any indication for PCI-S in patients deemed at high risk for bleeding and candidates for 1 month DAPT. This includes candidates with stable angina, silent ischemia, ACS (STEMI and non-STEMI), non-native lesions and in-stent restenosis. Patients must provide written informed consent.

Exclusion Criteria:

1. Pregnancy

9. A known hypersensitivity or contraindication to aspirin, clopidogrel (or prasugrel, or ticagrelor if applicable), stainless steel, Biolimus A9 or a sensitivity to contrast media, which cannot be adequately pre-medicated.
10. Participation in another clinical trial (12 months after index procedure).
