The clinical utility of transesophageal echocardiography (TEE) is well established for patients undergoing cardiac surgery and with the increase in percutaneous structural heart disease procedures that rely on TEE for procedural guidance the use of TEE probes is expanding. Although there are well established protocols for the routine cleaning and decontamination of the TEE probes between patient use, there is a lack of awareness and misconceptions about the maintenance of the structural and electrical integrity of TEE probes. The electrical leakage test (ELT) is one such test routinely performed between patient use. The ELT is necessary from a patient safety standpoint, to ensure the longevity of this expensive equipment as well as to prevent disruptions to the workflow in a busy department caused by TEE probes being decommissioned due to probe damage. This technical communication aims to highlight the importance of maintaining the structural and electrical integrity of TEE probes. The article also highlights and discusses probe handling techniques between patient use with a particular emphasis on the ELT to ensure patient safety and compliance with national and international standards.
