One of the least investigated aspects, however, is the mutual influence that two newly realized grafts can have. This possibility would be related to the presence of a more or less developed collateral circulation between the bypassed territories.\n\nThe purpose of this study is to assess whether a graft for a territory different than that provided by the left anterior descending artery (LAD) may affect the functionality (measured through flowmetry) of the left internal mammary artery - LAD graft.",[58,59,60],"Coronary Artery Disease","Coronary Stenosis","Coronary Bypass Graft Stenosis",[62,63,64,65],"coronary artery bypass","Transit Time Flowmetry","Intraoperative epicardial high-frequency ultrasound (HFUS)","Coronary anastomosis patency","NOT_YET_RECRUITING","2024-11-26",{"date":69,"type":70},"2024-11-27","ACTUAL",{"date":72,"type":54},"2024-11-20",{"date":74,"type":54},"2025-10-20",{"name":5,"class":6},1]
