Baseline characteristics comparing patients with and without perioperative screening with modified TEE. BMI = body mass index, DM = diabetes mellitus, COPD = chronic obstructive pulmonary disease, TIA = transient ischemic attack, PTCA = percutaneous transluminal coronary angioplasty, and LVEF = left ventricular ejection fraction.
