The diagnostic ability of pediatric transthoracic echocardiography in the current era : a segmental appraisal
Transthoracic echocardiography (TTE) plays a crucial role in the care of pediatric patients with heart disease. However, despite numerus recent technological advances, there has been little re-assessment of its accuracy. We sought to systematically assess the diagnostic accuracy of pediatric TTE in …

The NEST study: NICOM vs ECHO in the screening of transient hypertrophic obstructive cardiomyopathy (HOCUM)
… of techniques from electrical bioimpedance to transthoracic bioreactance. The appeal is that these investigations can be carried out at the patient’s bedside without a trained ECHO (Echocardiogram) technician. Aim: Our primary aim was to assess the ability of transthoracic bioreactance (a novel …
