'detailedDescription': 'Bioresorbable stents are promising in treatment of coronary artery disease. The concept of bifurcation treatment using BRS is particular appealing as struts covering the side branch ostium may resorb over time.\n\nThe aim of this study is to investigate the feasibility and safety of the Magmaris BRS for treatment of coronary bifurcation lesions.\n\nHypothesis: treatment of coronary bifurcation lesions using the Magmaris BRS is safe and feasible.\n\nMethods:\n\nThe study is a proof-of-concept, prospective, single arm study with inclusion of 20 patients. Planned 1-and 12-month follow-up by optical coherence tomography (OCT) and follow-up for clinical endpoints until 5 years.\n\nWritten informed consent is required before the procedure is performed. Eligible patients with a bifurcation lesion are treated by the provisional technique with mandatory jailing of the side branch and provisional opening of side branch ostium by the mini-kiss technique in case of severe pinching or TIMI-flow less than III. Proximal post-dilatation is mandatory. No dilatation beyond the expansion limits of the stent.\n\nAt baseline, the target lesion is assessed by OCT before, during and after implantation of the Magmaris BRS. OCT assessment is performed again at 1- and 12-month follow-up, or before if the patient is readmitted with a possible target lesion failure.\n\nThe operator is not blinded to the OCT images as pre-PCI images should be used for sizing and positioning of the stent, and procedural OCT images are used to optimize stent implantation before performing final OCT.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Stable angina pectoris\n* Stabilized non-ST elevation myocardial infarction\n* Silent angina pectoris\n* Age \\> 18 years\n* De novo coronary bifurcation lesion at LAD/diagonal, CX/obtuse marginal or RCA-PDA/posterolateral branch\n* All Medina classes except Medina x.x.1.\n* Diameter of side branch ≥ 2.5 mm\n* Side branch diameter stenosis less than 50%\n* Signed informed consent\n\nExclusion Criteria:\n\n* ST-elevation infarction within 48 hours\n* Expected survival \\< 1 year\n* Severe heart failure (NYHA≥III)\n* S-creatinine \\> 120 µmol/L or GFR \\< 0.45 mL/min per 1.73 m2\n* Allergy to contrast media, aspirin, clopidogrel, ticagrelor, ticlopidine or sirolimus\n* Unable to cover main vessel lesion with one stent\n* Severe tortuosity\n* Severe calcification'}, 'identificationModule': {'nctId': 'NCT03027856', 'acronym': 'BIFSORB P-II', 'briefTitle': 'The BIFSORB Pilot Study II', 'organization': {'class': 'OTHER', 'fullName': 'Aarhus University Hospital Skejby'}, 'officialTitle': 'A Sirolimus Eluting Bioresorbable Magnesium Stent for Treatment of Coronary Bifurcation Lesions - The BIFSORB Pilot Study II', 'orgStudyIdInfo': {'id': '1-10-72-194-16'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Magmaris', 'description': 'Implantation of sirolimus eluting bioresorbable magnesium stent', 'interventionNames': ['Device: Magmaris']}], 'interventions': [{'name': 'Magmaris', 'type': 'DEVICE', 'description': 'Implantation of a sirolimus eluting bioresorbable magnesium stent', 'armGroupLabels': ['Magmaris']}]}, 'contactsLocationsModule': {'locations': [{'zip': '8000', 'city': 'Aarhus N', 'country': 'Denmark', 'facility': 'Aarhus University Hospital', 'geoPoint': {'lat': 56.20367, 'lon': 10.17317}}], 'overallOfficials': [{'name': 'Evald H Christiansen, MD, PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Aarhus University Hospital'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'UNDECIDED'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Aarhus University Hospital Skejby', 'class': 'OTHER'}, 'responsibleParty': {'type': 'PRINCIPAL_INVESTIGATOR', 'investigatorTitle': 'Principal investigator (MD, PhD)', 'investigatorFullName': 'Evald Hoej Christiansen', 'investigatorAffiliation': 'Aarhus University Hospital Skejby'}}}}
