title = "Guidelines for the Use of Transesophageal Echocardiography to Assist with Surgical Decision-Making in the Operating Room: A Surgery-Based Approach: From the American Society of Echocardiography in Collaboration with the Society of Cardiovascular Anesthesiologists and the Society of Thoracic Surgeons",
abstract = "Intraoperative transesophageal echocardiography is a standard diagnostic and monitoring tool employed in the management of patients undergoing an entire spectrum of cardiac surgical procedures, ranging from “routine” surgical coronary revascularization to complex valve repair, combined procedures, and organ transplantation. Utilizing a protocol as a starting point for imaging in all procedures and all patients enables standardization of image acquisition, reduction in variability in quality of imaging and reporting, and ultimately better patient care. Clear communication of the echocardiographic findings to the surgical team, as well as understanding the impact of new findings on the surgical plan, are paramount. Equally important is the need for complete understanding of the technical steps of the surgical procedures being performed and the complications that may occur, in order to direct the postprocedure evaluation toward aspects directly related to the surgical procedure and to provide pertinent echocardiographic information. The rationale for this document is to outline a systematic approach describing how to apply the existing guidelines to questions on cardiac structure and function specific to the intraoperative environment in open, minimally invasive, or hybrid cardiac surgery procedures.",

note = "Funding Information: TEE is instrumental in refining preload, afterload, and inotropic support at separation from CPB by providing anatomic and functional information regarding LV and RV filling and function.AR in patients undergoing LVAD implantation is likely to progress due to lack of aortic valve opening, leaflet fibrosis, and fusion and retraction of the leaflet tips. The International Society of Heart Lung Transplantation recommends correction of moderate or higher degrees of pre-existing AR at the time of LVAD placement, since this may impact the long-term function and durability of the device.70 In patients with advanced heart failure, elevated LV diastolic pressure and reduced systemic vascular resistance combine to reduce the diastolic pressure gradient across the AV, which leads to underestimation of AR severity before LVAD implantation. Re-evaluation of AR should be repeated after institution of CPB when the LV is decompressed and there is direct flow into the ascending aorta through the aortic cannula, which may mimic to some degree the hemodynamic conditions during LVAD support.
