Figure 1: Diagnostic and therapeutic approach to persistent perioperative hypotension. Myocardial ischemia should be ruled out in patients with multiple cardiac risk factors. Rescue TEE is extremely helpful if equipment and expertise are available. CO = cardiac output; CAD = coronary artery disease; TEE = transesophageal echocardiography; TTE = transthoracic echocardiography; SVV = stroke volume variation; IV = intravenous; ECG = electrocardiograph; Hct = hematocrit
