On-line estimation of left ventricular stroke volume using transoesophageal echocardiography and acoustic quantification.
We have examined the usefulness of transoesophageal echocardiography (TOE) and automated endocardium detection for on-line calculation of left ventricular stroke volume. In 12 of 15 patients undergoing abdominal surgery, stroke volume was derived continuously from the multiple discs (MD) and area-length (AL) methods and compared with stroke volume calculated by thermodilution. In 10 patients (8...
متن کاملRealization of fully automated quantification of left ventricular volumes and systolic function using transthoracic 3D echocardiography
BACKGROUND Study on automated three-dimensional (3D) quantification of left heart parameters by using Heartmodel software is still in the early stage and fully automatic analysis was not clearly achieved. The aim of our study was to evaluate the performance of this new technology in measuring left ventricular (LV) volume and ejection fraction (EF) in patients with a variety of heart diseases on...
متن کاملRegurgitation Quantification Using 3D PISA in Volume Echocardiography
We present the first system for measurement of proximal isovelocity surface area (PISA) on a 3D ultrasound acquisition using modified ultrasound hardware, volumetric image segmentation and a simple efficient workflow. Accurate measurement of the PISA in 3D flow through a valve is an emerging method for quantitatively assessing cardiac valve regurgitation and function. Current state of the art p...
متن کاملquantification of aortic regurgitation severity by left ventricular to right ventricular stroke volume ratio
background: echocardiography is the most common test used for the evaluation of aortic regurgitation (ar). however, the role of echocardiography as an available and inexpensive method in the quantification of ar by the left ventricle to right ventricle stroke volume ratio (lv/rv sv ratio) has not been completely investigated. methods: between june 2005 and december 2007, 132 consecutive patient...
متن کاملModel driven quantification of left ventricular function from sparse single-beat 3D echocardiography
This paper presents a novel model based segmentation technique for quantification of left ventricular (LV) function from sparse single-beat 3D echocardiographic data acquired with a fast rotating ultrasound (FRU) transducer. This transducer captures cardiac anatomy in a sparse set of radially sampled, curved cross-sections within a single cardiac cycle. The method employs a 3D Active Shape Mode...
