CASE 1-2003. The use of intraoperative echocardiography during insertion of ventricular assist devices

Transesophageal echocardiography (TEE) assists in the intraoperative decision-making process during cardiac anesthesia and cardiac surgery. Mechanical ventricular support may be necessary to support the circulatory system temporarily or serve as a bridge to heart transplantation. A left ventricular assist device (LVAD) is most commonly used.1 Biventricular failure necessitates the use of an LVAD along with a right ventricular assist device (RVAD) to form a biventricular assist device (BIVAD) (Fig 1). TEE plays a vital role in evaluating effective mechanical assistance of the circulation.1-3 This case describes a BIVAD placement in a patient and shows the roles and limitations of TEE in this scenario.
