Determining the left ventricular (LV) end-diastolic volume index (EDVI) is essential to evaluating LV function. LV EDVI—the volume of blood in the LV at end load filling indexed for body surface area (ml/m 2)—may be quantified, .A common method for determining RV EDVI, also used when quantifying left ventricular (LV) EDVI and discussed further below, involves the manual segmentation of contiguous short-axis slices. LV EDVI is often acquired . End-diastolic volume refers to the quantity of blood in the left or right ventricle at the end of diastole, just before systole starts. The heart consists of four chambers: two atria and two.The percentage portions of papillary muscle and trabeculae to LV end-diastolic volume (EDV) and LV mass (LVM) were 11.9 ± 5.6% and 20.2 ± 4.3%, respectively, significantly affecting disease .
Six clinical indices were chosen and ranked based on their variance in the population: End-Diastolic Volume Index (EDVI), which is end-diastolic volume (EDV) divided by body surface area. Sphericity = EDV divided by the volume . The end-diastolic volume index (EDVI) is the ratio of the end-diastolic volume of the heart chamber to the body surface area. The ratio of left ventricular end-diastolic volume to .
EROA indicates effective regurgitant orifice area; LAVI, left atrial volume index; LV EDVI, left ventricular end-diastolic volume index; and PV, pulmonary vein.
LV end-diastolic volume index (EDVI) and end-diastolic flow velocity (EDFV) are the most feasible parameters for echocardiographic grading of AR severity. Using cardiovascular .The optimal view for measuring the left ventricular diastolic area is the left ventricular short axis view from the mid transgastric acoustic window. This view has been shown to be predictive of the LVEDV. The area is converted into left .EDD: end-diastolic dimension, EDVI: end-diastolic volume index, ESVI: end-systolic volume index, LV: left ventricular. from publication: Quantification of left ventricular remodeling in response . Background: Left ventricular (LV) ejection fraction (EF) and LV volumes were reported to have prognostic efficacy in cardiac diseases. In particular, the end-systolic volume index (LVESVI) has been featured as the most reliable prognostic indicator. However, such efficacy in patients with LVEF ≥ 50% has not been elucidated.
echocardiographic measures of LV size show limited agreement when classified according to currently recommended cut-offs. LV diameter should have a limited role in the assessment of LV size, particularly where a finding of LV dilation has important diagnostic or therapeutic implications. INTRODUCTION Left ventricular (LV) size is standardly The end-diastolic volume index (EDVI) is the ratio of the end-diastolic volume of the heart chamber to the body surface area. The ratio of left ventricular end-diastolic volume to body surface area is called left ventricular end-diastolic volume index (LVEDVI); similarly, the ratio of right ventricular end-diastolic volume to body surface area is called right ventricular . Left ventricular end-diastolic volume is the amount of blood in the heart’s left ventricle just before the heart contracts. While the right ventricle also has an end-diastolic volume, it’s the .1.

Accurate characterization of left ventricular (LV) hypertrophy (LVH) is important since an increased LV mass (LVM) due to various forms of hypertrophy and remodeling is both a risk factor for .
Recently, a report found that the strongest predictor of exercise capacity as defined as peak oxygen consumption (VO 2) in preterm individuals was mediated by LV EDVi, right ventricular EDVi, and LV mass index. 35 It is possible that a smaller preterm heart is capable of responding to pressure challenges because there is a lower preload . In the B, 4 patients from this cohort have the same normal value of LA end-diastolic volume indexed (EDVi; 10 mL/m 2) but different normal LV EDVi values (top), and 4 other patients with the same normal value of LV EDVi (60 mL/m 2) but different normal LA EDVi values (bottom). Although these values of LA EDVi or LV EDVi were identical, LACI . End-diastolic volume index is calculated as: EDVI = EDV/BSA [mL/m 2] Papillary muscles are often included in blood volumes or mass but not in both 1 . The ventricular outflow tract should also be included 2 .Objectives: Obtain normal reference ranges for left ventricular (LV) volume indexes (VI) and ejection fraction (EF) with fast real-time 3-dimensional echocardiography (RT3DE) with online analysis. Design: After a screening visit 166 healthy participants, 79 males and 87 females aged 29-80 years were examined with RT3DE and Doppler. .
Echocardiography remains the most widely used modality to assess left ventricular (LV) chamber size and function. Currently this assessment is most frequently performed using two-dimensional (2D) echocardiography. However, three-dimensional (3D) echocardiography has been shown to be more accurate and reproducible than 2D .Aims: To assess the agreement between left ventricular end-diastolic diameter index (LVEDDi) and volume index (LVEDVi) to define LV dilatation and to investigate the respective prognostic implications in patients with heart failure (HF). Methods and results: Patients with HF symptoms and LV ejection fraction (LVEF) < 50% undergoing cardiac magnetic resonance (CMR) were . Applying the ASE/EACVI guidelines, BSA-indexed LV end-diastolic volume (LVEDVi) and indexed LV end-diastolic diameter (LVEDDi) were assessed. Then, we identified 192 patients with at least mild LV end-diastolic dilatation by volumetric or linear measurements. Detailed information on left ventricular end-diastolic diameter (LVEDD), LVEDV, left ventricular end-systolic diameter (LVESD), BSA, left ventricular ejection fraction (LVEF), regional wall motion abnormalities, and valvular heart diseases was available for the included subjects. Past medical history, encompassing congenital heart disease .
We found LV EDVi to be a predictor of PH in severe AS, but it is not an early indicator, as it is found in the late phase of the disease, reflecting the pathological remodeling of the ventricle. In our study, patients had a normal or slightly reduced LV EF, while a significant correlation between LV EF and elevated sPAP was not found. LV EDVI, LVMI, SI, LS, s’, and E/e’ were higher in preterm group while RWT and EF were comparable between groups. LV showed normal geometry in 55.4%, physiological enlargement in 23% and .
The mean LV ejection fraction is 72 ± 6.4%. For patients with mild, moderate or severe MR the mean LV EDVI is 75 ± 10 ml/m 2 (range = 62 - 89 ml/m 2), 94 ± 8 ml/m 2 (range = 82 - 107 ml/m 2) and 119 ± 24 ml/m 2 (range = 98 - 167 ml/m 2) respectively. Figure 2 shows the relationships between regurgitant volume and LV EDVI, LV ESVI, LV ESD .

The left atrial end-systolic volume index (LAESVI), representing the largest left atrial (LA) volume, is a known predictor of cardiovascular outcomes and is the recommended measure of LA size by the American Society of Echocardiography. 1 The LA residual volume index or the LA end-diastolic volume index (LAEDVI) is the smallest LA volume, measured at .
LV EDVi correlated with RV EDVi (r=0.36, P<0.001). Patients with ToF and controls had similar heart rates (P=0.115; Table 1). In patients with ToF and healthy controls, LV volumes and mass correlated strongly with age, and the correlations remained moderate to strong if these LV parameters were indexed by BSA. Left ventricular (LV) volumes and ejection fraction (EF) are important predictors for morbidity and mortality in a wide range of patients and clinical scenarios ( 1–3). Traditionally, measurements of these parameters have been performed with 2-dimensional echocardiography (2DE) using the biplane Simpson's method. .
In a cohort of asymptomatic patients with AR, the presence of severe LV volume and diameter dilatation on the basis of the cutoff values proposed by current recommendations and normalized for BSA may be instrumental in the identification of patients at increased risk of clinical progression regardle .

We have compared echocardiography (echo) and radionuclide ventriculography (RNV) with magnetic resonance imaging (MRI) for the measurement of left ventricular (LV) volume and ejection fraction. Seventy asymptomatic patients were studied up to 12 days after first Q wave anterior myocardial infarction . The LV EDVI was calculated using Simpson biplane method from the apical 2- and 4-chamber views to quantify left ventricular end-diastolic volume and indexed to the body surface area. The vena contracta width was recorded in the modified parasternal long-axis view perpendicular to the commissural view in which the proximal jet size was the largest. This study investigated the association between the left ventricular end-diastolic volume index (LVEDVI) and the incidence of adverse clinical events in patients after MitraClip implantation. In this retrospective, observational study, 123 patients who underwent the MitraClip procedure were enrolled. Participants were divided into 2 groups .Background: A prognostic efficacy of Left ventricular ejection fraction (LVEF) in heart failure with preserved LVEF (HFpEF) is unclear. Methods: We enrolled 471 patients (LVEF>&=50%) who received a catheterization study and obtained baseline characteristics including LVEF, LV end-diastolic and end-systolic volume indices (LVEDVI, LVESVI) which were measured by left .
