COMBO-Stent in Patients on Chronic Anticoagulant Therapy (COSTA) COSTA-Bleed and COSTA-Outcome Trials

Inclusion Criteria: * Age 18 and older; * Willingness to comply with the study protocol; subject or a legally authorized representative must provide written informed consent prior to any study related procedure, in accordance with International Conference on harmonization of Good Clinical Practice (ICH-GCP) guidelines and per site requirements. * Patients on anticoagulant therapy or treatment-naive pa-tients with an indication to chronic anticoagulant therapy. Indications to oral anticoagulation may include atrial fibrillation, prosthetic valve disease, peripheral by-pass surgery, lung embolism or deep vein thrombosis or any other indication according to the Investigator´s opinion. * Single or multiple de novo lesion in a native coronary artery, all amenable to treatment with the COMBO stent; Exclusion Criteria: * Patients who, in the Investigator's opinion, should not be treated with (N)OAC. These may include, for instance: history of BARC 3-5 bleeding \<12 months; patients with a haemorrhagic disorder or bleeding diathesis (e.g. von Willebrand disease, haemophilia A or B or other hereditary bleeding disorder, history of spontaneous intra-articular bleeding, history of prolonged bleeding after surgery/intervention); patients with recent major surgery; history of intraocular, spinal, retroperitoneal, intra-articular or recent gastrointestinal bleeding unless the causative factor has been permanently eliminated or repaired; (reduction in the haemoglobin level of at least 2g/dL, transfusion of at least two units of blood, or symptomatic bleeding in a critical area or organ) including life-threatening bleeding episode (symptomatic intracranial bleeding, bleeding with a decrease in the haemoglobin level of at least 5g/dL or bleeding requiring transfusion of at least 4 units of blood or inotropic agents or necessitating surgery); Anaemia (haemoglobin \<10g/dL) or thrombocytopenia including heparin-induced thrombocytopenia (platelet count \<100E9/L) at screening; * Pregnant or nursing patients. Female patients of childbearing potential must have a negative pregnancy test done within 7 days prior to the index procedure per site standard test; * Other medical illness with a life expectancy \<2 years (e.g. known malignancy) or known history of substance abuse (alcohol, cocaine, heroin etc.) that may cause non-compliance with the protocol or confound the data in-terpretation or is associated with a limited life expectancy; * Patient has received an organ transplant or is on a wait-ing list for an organ transplant; * Known hypersensitivity or contraindication to antiplate-let or anticoagulant agents that does not allow guide-lines-compliant therapy and that cannot be adequately pre-medicated; * Previously received murine therapeutic antibodies and exhibited sensitization through the production of Human Anti-Murine Antibodies (HAMA); * Any significant medical condition which in the Investigator's opinion may interfere with the patient's optimal participation in the study; * Current participation in another investigational drug or device study except for non-interventional registries; * Patients not willing or able to comply with the protocol requirements or considered unreliable by the Investigator concerning the requirements for follow up during the study and/or compliance with study drug administration; Angiographic exclusion criteria: * Vessel diameter \<2 und \> 5mm; * Target lesion with characteristics that make it unsuitable for stent delivery and deployment; * Planned use of a stent or another coronary device in the same or another session (target vessel or non-target vessel), precluding a COMBO-only strategy.
