TOMTEC IMAGING SYSTEMS GMBH modules of 4d lv-analysis 3.1
Calculation of right ventricular pump efficiency. Three-dimensional echocardiography derived <t>volumetric</t> analysis yielded left ventricular stroke volume (A) and right ventricular volume to time curve (B). Conjugation of tricuspid regurgitation pressure gradient envelope (C) and right ventricular volume-to-time curve generates the pressure gradient-volume diagram (D) and the area under the curve is used to calculate the right ventricular stroke work (E). Right ventricular pump efficiency is calculated as left ventricular stroke volume divided by right ventricular stroke work.

A three-dimensional dynamic heart within one cardiac cycle. We show some snapshots of a reconstructed three-dimensional dynamic heart within one cardiac cycle using CardiacField, compared with that acquired by the three-dimensional echocardiography probe. The electrocardiogram is used to indicate the phases within one cardiac cycle.

Figure Lengend Snippet: A three-dimensional dynamic heart within one cardiac cycle. We show some snapshots of a reconstructed three-dimensional dynamic heart within one cardiac cycle using CardiacField, compared with that acquired by the three-dimensional echocardiography probe. The electrocardiogram is used to indicate the phases within one cardiac cycle.

Article Snippet: Similarly, RV volumes and EFs were assessed using RV-focused 3D echocardiography (4D RV-Function, TomTec Imaging).

Techniques:

Calculation of right ventricular pump efficiency. Three-dimensional echocardiography derived volumetric analysis yielded left ventricular stroke volume (A) and right ventricular volume to time curve (B). Conjugation of tricuspid regurgitation pressure gradient envelope (C) and right ventricular volume-to-time curve generates the pressure gradient-volume diagram (D) and the area under the curve is used to calculate the right ventricular stroke work (E). Right ventricular pump efficiency is calculated as left ventricular stroke volume divided by right ventricular stroke work.

Figure Lengend Snippet: Calculation of right ventricular pump efficiency. Three-dimensional echocardiography derived volumetric analysis yielded left ventricular stroke volume (A) and right ventricular volume to time curve (B). Conjugation of tricuspid regurgitation pressure gradient envelope (C) and right ventricular volume-to-time curve generates the pressure gradient-volume diagram (D) and the area under the curve is used to calculate the right ventricular stroke work (E). Right ventricular pump efficiency is calculated as left ventricular stroke volume divided by right ventricular stroke work.

Article Snippet: 27 - 29 The 3D echocardiographic datasets were analyzed offline with modules for LV and RV volumetric analyses (Modules of 4D LV-Analysis 3.1 and 4D RV-Function 2.0, TTA 2.3, TomTec Imaging Systems, Unterschleissheim, Germany) to report left ventricular end-diastolic volume index (LVEDVi), left ventricular end-systolic volume index (LVESVi), left ventricular stroke volume index (LVSVi), left ventricular ejection fraction (LVEF), left ventricular global longitudinal strain (LVGLS), left ventricular global circumferential strain (LVGCS), right ventricular end-diastolic volume index (RVEDVi), right ventricular end-systolic volume index (RVESVi), RVEF, peak systolic longitudinal right ventricular free wall strain (RVLSfw) and peak systolic longitudinal right ventricular septal wall strain (RVLSsep). illustrates the non-invasive calculation of single-beat RV pump efficiency.
