Bypass Graft Stenosis

Cardiac surgery, pericardial closure, grafts, bypass, aortocoronary bypass
Brief summary
Once the pericardium is closed, there is no information on the hemodynamics of the grafts after coronary artery bypass grafting. This would be the reason for different opinions on pericardial closure: some teams do not close the pericardium and others close it. In the department Cardiovascular Surgery of the University Hospital of Saint-Etienne, the Medistim machine is used in routine and the hemodynamic properties of the grafts are recorded immediately after the bypass surgery, before the closure of the pericardium.
Detailed description
The aim of the study is to have hemodynamic information immediately after the closure of the pericardium using the Medistim machine. The prospective study will be conducted on 50 patients, who will be selected consecutively without randomization. The inclusion and exclusion criteria are determined.
Interventions
Datas will be collected by Medistim machine before and after pericardial closure: Flow through the grafts, Resistance on grafts, Pulsatility of the grafts, Systolic and diastolic curves before and after pericardial closure
