Freehand Three‐Dimensional Echocardiography with Rotational Scanning for Measurements of Left Ventricular Volume and Ejection Fraction in Patients with Coronary Artery Disease

Abstract

Three-dimensional echocardiography using magnetic tracking system and average rotational geometry offered a feasible and accurate method for quantification of LV volumes and EF in patients with CAD.

Importance of transesophageal echocardiography in the critically ill and injured patient

“…As one would expect, numerous patients with "acceptable" filling pressures (from the PAC) did in fact have inadequate filling. This reaffirms what is previously stated in acidotic conditions with impairment of ventricular performance and the lack of tissue oxygenation (47,(65)(66)(67)(68).…”

Overestimation of Left Ventricular Mass and Misclassification of Ventricular Geometry in Heart Failure Patients by Two‐Dimensional Echocardiography in Comparison with Three‐Dimensional Echocardiography

“…LV mass was calculated by the ASE 17 method according to recommendations of the American Society of Echocardiography 18 . Freehand 3D echocardiography was performed in each subject using equipment and methods that have been described previously, 19 and validated with explanted hearts, 14 magnetic resonance imaging, 19 and myocardial perfusion gated SPECT 20,21 …”

Analysis of Left Ventricular Changes After Acute Myocardial Infarction Using Transthoracic Real-Time Three-Dimensional Echocardiography

“…With advances in real-time 3-D echocardiography, calculation of LV volume has become more accurate than with 2-D echocardiography. 2,11,12 Volumetry by 2-D echocardiography depends on geometric assumptions and is subject to image-plane positioning errors. In conditions where the LV is distorted in shape such as after an AMI and ischemic cardiomyopathy, LV assessment is not accurate using 2-D methods.…”

“…In conditions where the LV is distorted in shape such as after an AMI and ischemic cardiomyopathy, LV assessment is not accurate using 2-D methods. 11,12 Recently, Mannaerts et al 6 reported that 3-D DSI is >25% in the acute stage of an AMI identified patients who developed remodeling 6 or 12 months after AMI. In addition, they also found that 3-D EDV and ESV were also predictors of impending LV remodeling after AMI.…”
