The aim of the present study is investigation of the relationship between left ventricular failure after mitral regurgitation surgery and following factors; intraoperative cerebral tissue oxygen saturation, intraoperative plasma reactive oxygen species levels, central venous oxygen saturation, and mixed venous oxygen saturation.
Efficacy
The primary outcome is postoperative left ventricular failure. It is defined that left ventricular ejection fraction is less than 50 %, which measurement is performed in transthoracic echocardiography during postoperative 5 - 21 days.
