The ASE TTE iPad App 2.0.1 provides all of the animated content from the American Society of Echocardiography’s DVD entitled "How to Perform a Transthoracic Echocardiographic Study Volume 1: Transducer Position and Anatomy”. Like the DVD, the App includes an instructional video to be used for professional lectures including nonlinear access to views for flexible presentations. The video includes an overview of relevant cardiac anatomy, a step by step presentation of all Transducer Positions, and the sequential transducer movements to acquire standard echo images needed to complete a Transthoracic Echocardiographic Study. The cardiac anatomy section visualizes relationships of the heart, ribs, axis of the heart, planes of the heart and aorta, chambers, valves and annuli, and blood flow through the heart. The transducer position menu allows the user to view the anatomical landmarks and the transducer positions for left parasternal, apical, subcostal, suprasternal and right parasternal image acquisition. The views and imaging menu allows the user to navigate from a particular transducer position menu, such as left parasternal long to specific images acquired within that window, such as PLAX high depth, PLAX low depth, and PLAX Zoom of the Aortic and Mitral Valves. Each animated loop shows a finder image in the upper left that depicts the transducer position, an illustration of the sectional anatomy of the heart on the left, and the echo image with labels on the right.
