The Particulars: Several organizations support the use of three-
dimensional (3D) transesophageal echocardiography (TEE) as an
advanced diagnostic application for cardiac surgical patients.
Acquiring and interpreting TEE images remains conceptually
challenging for trainees. Data Breakdown: Researchers at Duke
University developed a 3D iPad app that allowed trainees in TEE
to obtain real-time instruction in obtaining and interpreting
high-quality images of the heart and major vessels. Software
programs were created to annotate instructional movies based on
video acquired using esophageal ultrasound probes. Trainees had
the capability to view these movies on their iPads. Take Home
Pearl: An iPad app appears to provide trainees in TEE with an
effective portable teaching tool that can be used while
performing an examination in real-time in the operating room.
