Simulation provides a learning environment suitable for procedures that require repetition without adding to patient risk.1–3 The Heartworks TEE (transoesophageal) Simulator by InventiveMedical is readily available to anaesthesia trainees at our centre. It allows navigation between 20 standard echocardiographic views. It consists of a high-end software loaded computer and screen, a mannequin and a dummy probe. The display consists of a 3D model of the heart, the probe position and an ultrasound image. The echo image and heart model will vary corresponding to alterations in probe orientation. This is called the haptic interface.4

This prospective, observational study was designed to evaluate the educational benefit of the Heartworks TEE Simulator as an adjunct to teaching anaesthesia trainees basic TEE. The hypothesis stated that a 1:1 trainee to instructor TEE simulation session would produce a significant improvement in post-test multiple choice questionnaire scores compared with pretest scores.

Twenty-two anaesthesia trainees undertaking their cardiothoracic anaesthesia module completed a presession multiple choice questionnaire; this lasted for 30 min. Thirty computer-based multiple choice questions with single best answer, including video clips of the …
