Acrobat Coronary Stent System Effectiveness European Study

Study Overview
=================
Brief Summary
-----------------
The purpose of this randomized controlled trial (RCT) is to demonstrate the clinical benefit and impact on resource utilization of percutaneous coronary interventions (PCI) with the Svelte Acrobat Stent System compared to any other CE marked bare metal stent (BMS) implantable via direct stenting or after lesion pre-dilation, in patients with coronary lesions that are eligible for direct stenting and who are recruited and treated so as to reflect real-life routine practice.

Detailed Description
-----------------
The main objectives of this study are to test the following hypotheses: The evaluated stent is clinically non-inferior to control BMS in terms of freedom of MACE The evaluated stent is clinically beneficial compared to control BMS by reducing exposure to radiations, amount of contrast medium administered, procedure time, as well as amount of administered heparin, The evaluated stent does not result in more frequent adverse events than control BMS, The evaluated stent improves direct stenting success while not decreasing procedural success compared to control BMS. Resource utilization (R.U.): Hospital-perspective resource utilization during the index admission and index procedure is not greater with evaluated the stent and potentially lower than with control BMS Resource utilization over a 6-month time-horizon, in relation to routine follow-up and MACE, is not greater with the evaluated stent than with control BMS.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of patients free of Major Adverse Cardiac Event (MACE-free patients) | Major Adverse Cardiac Event (MACE) is defined here as device-oriented composite endpoint that includes, in hierarchical order: Cardiac death (All deaths are considered cardiac unless an unequivocal non-cardiac cause can be established), Myocardial Infarction (MI), Target Lesion Revascularization (TLR). | From the date and time of randomization until 6 months after the index procedure | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| administered dye | Volume (ml) of administered dye i.e. injected radiological contrast medium. | intra-procedural | 
| procedure duration | Procedure duration (minutes) from arterial access to closure. | intra-procedural | 
| radiation exposure | Radiation exposure (gY/cm²) & total fluoroscopy time (min) | intra-procedural | 
| acute success | Acute success is measured at procedure end according to 4 criteria: Lesion success: Residual stenosis of the target lesion < 30% of the RVD using any percutaneous method. Direct stenting success: Lesion success without unplanned pre-dilation performed (planned pre-dilation is an exclusion criterion) from the trial. Device Success: Direct stenting success without post-dilatation or with post-dilatation using the Stent Delivery System (SDS). Procedure success: Lesion success & no in-hospital MACE | procedure to discharge | 
| heparin administration | Amount of heparin administered during the procedure | intra-procedural | 
| adverse events | Adverse events occurrence: Death MI Repeat coronary revascularization Bleeding or vascular complications at discharge Stent thrombosis up to 6 months Other serious adverse events | 6 months |
