Results of a Prospective Echocardiography Trial in International Space Station Crew

In the framework of an operationally oriented investigation, we conducted a prospective trial of a standard clinical echocardiography protocol in a cohort of long-duration crewmembers. The resulting primary and processed data appear to have no precedents. Our tele-echocardiography paradigm, including just-in-time e-training methods, was also assessed. A critical review of the imaging technique, equipment and setting limitations, and quality assurance is provided, as well as the analysis of "space normal" data.
