Impact of Modified Transesophageal Echocardiography on Mortality and Stroke after Cardiac Surgery: A Large Cohort Study

Table 3

Operative characteristics comparing patients with and without perioperative screening with modified TEE. Percentage of patients with isolated coronary revascularization. CABG = coronary artery bypass grafting, CK = Creatinin Kinase, and CKMb = Creatinin Kinase MB isoenzyme.
