A minimum dataset for a standard transoesophageal echocardiogram: a guideline protocol from the British Society of Echocardiography

Abstract

A systematic approach to transoesophageal echocardiography (TOE) is essential to ensure that no pathology is missed during a study. In addition, a standardised approach facilitates the education and training of operators and is helpful when reviewing studies performed in other departments or by different operators. This document produced by the British Society of Echocardiography aims to provide a framework for a standard TOE study. In addition to a minimum dataset, the layout proposes a recommended sequence in which to perform a comprehensive study. It is recommended that this standardised approach is followed when performing TOE in all clinical settings, including intraoperative TOE to ensure important pathology is not missed. Consequently, this document has been prepared with the direct involvement of the Association of Cardiothoracic Anaesthetists (ACTA).
