Left ventricular volume and ejection fraction assessment with transoesophageal echocardiography: 2D vs 3D imaging

Left ventricular volume and ejection fraction assessment with transoesophageal echocardiography: 2D vs 3D imaging.

BACKGROUND Developments in transducer technology have enabled the use of three-dimensional transoesophageal echocardiography (3D TOE) in the operating theatre. Transthoracic echocardiography (TTE) 3D left ventricular (LV) volumes and ejection fraction (EF) agree better with magnetic resonance imaging (MRI) measurements, with less intra- and inter-observer variability compared with 2D. This has ...

Quantitative assessment of left ventricular volume and ejection fraction using two-dimensional speckle tracking echocardiography.

AIMS Two-dimensional speckle tracking echocardiography (2DSTE) allows measurements of left ventricular (LV) volumes and LV ejection fraction (LVEF) without manual tracings. Our goal was to determine the accuracy of 2DSTE against real-time 3D echocardiography (RT3DE) and against cardiac magnetic resonance (CMR) imaging. METHODS AND RESULTS In Protocol 1, 2DSTE data in the apical four-chamber v...

Assessment of left ventricular volumes and ejection fraction with 16-slice multi-slice computed tomography; comparison with 2D-echocardiography.

BACKGROUND In recent years, multi-slice computed tomography (MSCT) has emerged as a rapidly expanding modality for non-invasive assessment of coronary artery disease. Simultaneously, left ventricular (LV) function can be evaluated although this is not yet a routine component of an MSCT examination. Accordingly, the purpose of the present study was to validate assessment of LV function with MSCT...

Continuous assessment of right ventricular ejection fraction: new pulmonary artery catheter versus transoesophageal echocardiography.

In 25 cardiac surgical patients, right ventricular ejection fraction was continuously measured with a new pulmonary artery catheter and transoesophageal echocardiography, scanning the 'fractional area change' in a standardised transatrial cross section area. Measurements were recorded at three predefined time points (pre-, intra-, and postoperatively). Both methods were compared using the Bland...
