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.",[74,75],"Coronary Arterial Disease (CAD)","Bypass Graft Occlusion","NOT_YET_RECRUITING","2025-07-02",{"date":79,"type":80},"2025-07-08","ACTUAL",{"date":82,"type":68},"2025-09-01",{"date":84,"type":68},"2028-01-01",{"name":53,"class":6},1]
