However, studies have shown that up to one third of patients will have closure of at least one bypass graft (graft failure) after one year, which has prognostic implications. Since graft failure can partly be due to inappropriate placement of the distal graft anastomosis, there is a need to develop new surgical methods to ensure optimal placement of the grafts. Three-dimensional (3D) printing is a technique developed to transform digital objects into physical models. The method is widely used in orthopedic surgery and maxillofacial surgery, but has also gained interests in cardiology, and has proved usefull in the preparation for invasive interventions or surgery in patients with complicated anatomy, including congenital heart disease.\n\nThe purpose of the study is to investigate, if a surgical strategy, based on a preoperative cardiac CT, including a patient-specific printed 3-D model of the coronary vessels, marked with optimal bypass graft insertion points, can reduce graft failure, assessed by a control cardiac CT examination performed 12 months after surgery. The hypothesis is that 3-D printing of coronary vessels determined from invasive coronary angiography and cardiac CT prior to CABG reduces graft failure 12 months after surgery.",[26,27],"Coronary Arterial Disease (CAD)","Bypass Graft Occlusion","NOT_YET_RECRUITING","2025-07-02",{"date":31,"type":32},"2025-07-08","ACTUAL",{"date":34,"type":20},"2025-09-01",{"date":36,"type":20},"2028-01-01",{"name":38,"class":39},"Jesper James Linde","OTHER",1,{"id":42,"slug":43,"hasResults":11,"nctId":44,"briefTitle":45,"officialTitle":45,"acronym":4,"eligibilityCriteria":46,"healthyVolunteers":11,"sex":16,"minAge":17,"maxAge":47,"enrollmentInfo":48,"targetDuration":4,"studyType":21,"phases":50,"briefSummary":51,"conditions":52,"keywords":4,"overallStatus":62,"whyStopped":4,"lastUpdateSubmitDate":63,"lastUpdatePostDateStruct":64,"startDateStruct":66,"completionDateStruct":68,"leadSponsor":70,"locationsCount":40},"100582017","myocardialbridge-bypass-graft-surgery-efficacy-verification-100582017","NCT06857838","Myocardialbridge Bypass Graft Surgery Efficacy Verification","Inclusion Criteria:\n\n* Patients with myocardialbridge requiring drug therapy or surgical intervention.\n\nExclusion Criteria:\n\n* patients with myocardialbridge not requiring drug therapy or surgical intervention, or unwilling to be enrolled for any reason","80 Years",{"count":49,"type":20},500,[23],"Myocardial Bridge Bypass Graft surgery is introduced to relieve the unmedical symptoms of patients with long-segment or deep myocardial bridge, clinical outcomes will be collected to verify the effectiveness of the surgery.",[53,54,55,56,57,58,59,60,27,61],"Myocardial Bridge of Coronary Artery","Myocardial Bridge","Myocardial Bridging","Myocardial Infarction","Myocardial Ischemia","Pectoris, Stable Angina","Sudden Cardiac Death","Bypass Graft Stenosis","Bypass Graft Thrombosis","RECRUITING","2025-02-26",{"date":65,"type":32},"2025-03-04",{"date":67,"type":32},"2020-01-01",{"date":69,"type":20},"2040-12-31",{"name":71,"class":39},"Xi'an International Medical Center Hospital"]
