title: The role of state-of-the-art echocardiography in the assessment of myocardial injury during and following cardiac surgery.
abstract: Use of intraoperative echocardiography during open heart surgery, transesophageal probes, high-frequency transducers, and color Doppler imaging provide important diagnostic information to surgeons and anesthesiologists. Early detection of myocardial ischemia, assessment of valvular disorders, and the ability to monitor for intracardiac air are among the most important roles of intraoperative transesophageal echocardiography. Large prospective studies are necessary to evaluate whether these changes affect the outcome of patients undergoing coronary artery bypass grafting in terms of morbidity, mortality, hospital length of stay, and functional recovery. The application of new techniques such as contrast-enhanced transesophageal echocardiography helps to assess the adequacy of cardioplegia distribution and, thus, myocardial protection during cardiopulmonary bypass, which has a significant influence on outcomes as well.
