Diagnostische Genauigkeit neuer tragbarer Echokardiographiegeräte mit Doppler und Harmonic Imaging—

摘要

The first generation of hand-held echocardiography devices was evaluated with divergent results due to inherent technical limitations. New hand-held devices with cw/pw Doppler as well as tissue harmonic imaging were introduced recently. In this study, comparisons were drawn between standard echocardiography and invasively measured systolic pulmonary artery pressure and these new devices.Two consecutive echocardiographic examinations were performed by experienced and independent examiners using handheld echocardiography and standard echocardiography. The hand-held device was a SonoSite 180plus (SonoSite Inc. Washington, USA). Standard devices employed included Vingmed Vivid 5&7 (GE, Horten, Norway). Systolic pulmonary artery pressure was measured by Swan-Ganz catheter.
