Design outcomes

Primary

Measure	Time frame
Concordance rate between cardiac output measured by new measurement method using transesophageal echocardiography and cardiac output measured by pulmonary artery catheterization	—

Secondary

Measure	Time frame
Correlation between cardiac output measured by new measurement method using transesophageal echocardiography and cardiac output measured by pulmonary artery catheterization. Association between cardiac output or cardiac power output and postoperative complications (death, myocardial infarction, cerebral infarction, non-occlusive mesenteric ischemia, acute kidney injury) and surrogate markers (lactic acid level, mixed venous oxygen saturation).	—
