Impact of a one-day three-dimensional transesophageal echocardiography workshop on clinical practice at a single...

Transesophageal echocardiography (TEE) is a powerful diagnostic tool which has become an integral part in the management of cardiac surgery patients. We developed a one-day 3D TEE workshop specifically designed to meet the needs of perioperative cardiac anaesthesiologists. We hypothesized that participation in the workshop would increase the uptake of 3D TEE in routine perioperative practice.

To examine the impact of one-day 3D TEE workshop on 3D TEE image acquisition and incorporation into routine perioperative practice.

Tertiary care hospital.

Prospective observational monocentric study.

A convenience sample of 20 cardiac anesthesiologists (with an option to attend the one- day workshop midway through the study) from a single center consented to have their intraoperative TEE images collected during the course of the study reviewed for research purposes. Images acquired 6 months before, immediately after, and 6 months following the workshop and images were examined by a blinded, expert echocardiographer.

Data collected for 16 participants (8 workshop attendees, 8 non-attendees) indicate that the TEE workshop increased the number of 3D TEE images, but not x images acquired immediately following the workshop (P=0.006). No difference was observed in number of 3D images at six months' post workshop. Workshop participants obtained more 3D and multi-plane images after the workshop and more 3D images at 6 months compared to those who did not attend the workshop.

Our study suggests that a single day hands-on 3D TEE workshop may have had an impact on the implementation of intraoperative 3D TEE in experienced echocardiographers.
