Brief Summary:
The purpose of this study is to determine whether patients undergoing coronary intervention that also require oral anticoagulation, treatment with the COBRA PzF stent plus 14-day dual anti-platelet therapy (DAPT) has higher safety and non-inferior outcomes for thrombo-embolic events than compared with standard FDA-approved drug eluting stent (DES) plus 3 or 6-month DAPT.
