Summary

Introduction: Aorta no-touch off-pump coronary artery bypass surgery (OPCAB) has been the recommended technique for treatment of patients with high-risk of neurological damage or stroke. However, the displacement of the heart to achieve suitable exposure for graft construction elicits hemodynamic changes, potentially requiring conversion to on-pump. Objective: The aim of this study is to evaluate the sequential changes of hemodynamic parameters in patients that undergo aorta no-touch OPCAB. Method: Patients that undergo aorta no-touch OPCAB will be evaluated. The FloTrac / PreSep / Vigileo ™ (Edwards Lifesciences) system will be used to continuously record heart rate (HR), mean arterial pressure (DBP), central venous pressure (CVP), continuous cardiac index, systolic volume , systolic volume variation (VVS) and central venous oxygen saturation (ScvO2). The parameters will be evaluated 5 min before, during and 5 min after each anastomosis (left anterior descending-LAD, posterior descending PD, marginal-OM and diagonal-Dg). Postoperative lactate will also be evaluated.
