    Abstract:
    To assess the usefulness and safety of transesophageal echocardiography in critically ill patients, we analysed the transesophageal echocardiography studies in 60 of such cases (age: 58 +/- 11 and 38 males). Every patient underwent a previous transthoracic echocardiogram, that was considered inadequate for diagnostic purposes. Thirty patients (50%), were on mechanical ventilation and 17 patients (28%) showed hypotension and/or shock. Forty patients (66%) were at special care units and in 31 (52%) of them, pulmonary and systemic pressures, and continuous analysis of venous pressure of oxygen were available. Indications for study were: 17 patients with clinical suspicion of aortic dissection (confirmed in 5 cases): 9 patients infective endocarditis (4 cases showed valvular vegetations); 6 patients with mitral prosthesis dysfunction (confirmed in 4 cases); complicated acute myocardial infarction (MI) in 8 patients (2 cases with mitral insufficiency, 3 with left ventricular dysfunction, 1 with right ventricular MI, 1 with left ventricular pseudoaneurysm and other with isolated inferior MI); in 11 patients the study was performed to evaluate the result of cardiac transplantation immediately (< 4 h) and it showed 2 cases of left ventricular dysfunction; 3 patients were studied for severe cardiac dysfunction of unknown etiology (a dilated cardiomyopathy was confirmed in one and ruled out in the other, and one patient showed signs of restrictive situation); there were other causes in the rest. The procedure could be completely performed in all cases. In conclusion in critically ill patients the transesophageal echocardiography has a great usefulness and minimal complications.
