11. Participant has a chronic systemic condition or medication likely to interfere with coronary physiology and/or conduit artery function (e.g., chronic inflammatory condition, chronic renal failure, or chronic obstructive pulmonary disease).
12. Participant has known renal insufficiency.

16. Elective surgery is planned within the first 6 months after the index procedure that will require discontinuing aspirin, clopidogrel, prasugrel, or ticlopidine.
17. Participant has a platelet count < 100,000 cells/mm3 or > 700,000 cells/mm3, a WBC of < 3,000 cells/mm3, or documented or suspected liver disease (including laboratory evidence of hepatitis) within 7 days prior to the index procedure.

20. Participant has had a significant gastro-intestinal or significant urinary bleed within the past 6 months.
21. Participant has extensive peripheral vascular disease that precludes safe 6 French sheath insertion.
22. Participant has a history of paradoxical exercise-induced vasoconstriction that is consistent with myocardial bridging in the coronary anatomy.
23. Participant has other medical illness (e.g., cancer or congestive heart failure) or known history of substance abuse (alcohol, cocaine, heroin etc.) that in the judgment of the Investigator may cause non-compliance with the clinical investigation plan, confound the data interpretation or is associated with a limited life expectancy.
24. Participant is currently participating in another clinical investigation that has not yet reached its primary endpoint.
25. Percutaneous interventions for lesions in the third major epicardial vessel (the one that does not contain the target or the self-control vessel) were performed within 30 days preceding the index procedure or are planned to be done within 6 months following the index procedure.
26. Planned PCI procedures in the target vessel (and/or any of its side branches) or the self-control vessel (and/or any of its side branches) within 2 years following the index procedure.
27. Participant who does not suspend drugs that will influence vaso-function.
Angiographic Exclusion Criteria
1. Target lesion meets any of the following criteria:
1. Left main location;
2. RCA aorto-ostial location (within 10 mm from expected proximal stent/scaffold edge);
3. LAD or LCX ostial location (within 10 mm from expected proximal stent/scaffold edge);
4. Involves a bifurcation with a side branch = 2 mm in diameter, an ostial lesion > 40% stenosed by visual estimation, or a side branch requiring pre-dilatation;
5. Total occlusion (TIMI flow 0) prior to wire crossing;
6. Excessive tortuosity proximal to or within the lesion;
7. Extreme angulation (= 90°) proximal to or within the lesion;
8. Heavy calcification in the lesion;
9. Located in a side branch.
2. Participant has a high probability that a procedure other than pre-dilatation, scaffold/stent implantation, and post-dilatation (if applicable) will be required at the time of index procedure for treatment of the target vessel (e.g., atherectomy, cutting balloon or brachytherapy).
3. The target vessel (and/or any of its side branches) or the self-control vessel (and/or any of its side branches) contains visible thrombus.
4. The target vessel or the self-control vessel has previously been treated by any PCI procedures.
5. A side branch of the target vessel or a side branch of the self-control vessel has received any percutaneous interventions within 30 days prior to the index procedure.
6. Another clinically significant lesion is located in the target vessel (and/or any of its side branches) or the self-control vessel (and/or any of its side branches) that may require PCI treatments within 2 years following the index procedure.
7. Participant has evidence of myocardial bridging in the coronary anatomy during the angiographic evaluation.

Summary
Brief summary
The target enrollment goal for the trial was to enroll 36 subjects. However due to a challenging protocol inclusion/ exclusion criteria, only one subject was enrolled since the trial was initiated in June 2011. To evaluate the following in participants undergoing coronary artery scaffolding/stenting for significant coronary artery disease: * The acute (post-implantation) effect of an implanted bioresorbable vascular scaffold (BVS) or metallic drug eluting stent (mDES) on coronary blood flow and physiological responsiveness of the target coronary artery * The long-term (2 years) effect of an implanted BVS or mDES on coronary blood flow and physiological responsiveness of the target coronary artery
