The Role of Automated 3D Echocardiography for Left Ventricular Ejection Fraction Assessment

Left ventricular ejection fraction (LVEF) is the most widely used parameter of left ventricular (LV) systolic function, and its deterioration is associated with reduced survival rates.1 LVEF is expressed as a percent value, and calculated by dividing the stroke volume (enddiastolic volume minus end-systolic volume) by the end-diastolic volume and multiplying by 100; however, volume measurements entail a much higher complexity.2 Despite these limitations, noninvasive imaging has become the mainstay for the assessment of LV volumes and ejection fraction

Novel Imaging Techniques for Heart Failure

Heart failure (HF) is an epidemic with an increasing prevalence and an absolute mortality rate of approximately 50 % within 5 years of diagnosis. Imaging plays a main role in HF diagnosis, assessment of aetiology and treatment guidance. This article reviews current HF applications for all the available non-invasive imaging modalities: echocardiography, cardiovascular magnetic resonance (CMR), nuclear imaging-positron emission tomography (PET) and single-photon emission computed tomography (SPECT) and computed tomography (CT).
