Abstract
Weaning a patient from mechanical assist circulation (MAC) at the optimal time is a determining factor for his survival. However, information available to determine the optimal timing is usually limited in an intensive care unit (ICU), because the patient is supported by a heavy circulation assist system, which prevents him or her being transfered to the cardiac examination laboratories. Transthoracic echocardiography may be effective in evaluating perioperative cardiac function in some cases, but in an ICU the echo penetration is usually poor because the patients are on ventilators and receiving some positive end-expiratory pressure assistance. Transesophageal echocardiography (TEE) can usually give a reasonably good echo window even in such a circumstance in ICU, because with this technique there is no obstruction by the lung, sternum, or ribs and so distinct and stable images can be obtained in the deeper area of the thoracic cavity [1, 7]. The purpose of this study was to evaluate the clinical feasibility and effectiveness of TEE, including color flow mapping Doppler [9], in management of patients during MAC.
