To the Editor:
A recent study by Rosenberger et al. (1) reported a relatively low sensitivity (26%) for direct visualization of pulmonary thromboemboli using intraoperative transesophageal echocardiograpy (TEE). The authors conclude that "TEE is not reliable for directly visualizing pulmonary emboli in the intraoperative setting of pulmonary embolectomy." In such cases, we suggest an additional, complimentary technique: examination of the proximal pulmonary vasculature with an epicardial echocardiographic probe placed directly on the proximal pulmonary arterial system. Such use of an epicardial echocardiographic probe may permit visualization of pulmonary thromboemboli that are not visualized by TEE and may be used to guide surgery (2). It is important that anesthesiologists providing intraoperative care for cardiac surgical patients be cognizant that intraoperative epicardial and epiaortic echocardiographic examination yield information in addition to that obtained by TEE and can be accomplished in a reasonably timely fashion (3).
