Studies have shown that, as compared to conventional sternotomy, patients underwent robot-assisted bypass grafting or valvuloplasty had less post-operation pain, blood transfusion volume during operation, re-operation rate, post-operation stroke rate and length of hospitalization. However, most studies focused on the comparison of complications of different procedures, and the investigation of cardiopulmonary function recovery is still lacking.

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.",[56,57,23],"Coronary Artery Disease","Coronary Stenosis",[59,60,61,62],"coronary artery bypass","Transit Time Flowmetry","Intraoperative epicardial high-frequency ultrasound (HFUS)","Coronary anastomosis patency","2024-11-26",{"date":65,"type":33},"2024-11-27",{"date":67,"type":19},"2024-11-20",{"date":69,"type":19},"2025-10-20",{"name":71,"class":40},"Fondazione Policlinico Universitario Agostino Gemelli IRCCS"]
