“…STE provides deformation information of the LV, which has been reported to be valuable in identifying preclinical or subtle myocardial dysfunction. 14 – 16 , 26 , 30 STE has been used in TAV to evaluate cardiac mechanics in AS and AR patients, which revealed lower deformation in asymptomatic/symptomatic patients with normal LVEF when compared with healthy controls. 17 – 20 Few reports are available on BAV cardiac mechanics, 31 – 33 and none of them reported the subtle mechanical changes based on valvular lesion types.…”

“…Speckle tracking echocardiography (STE) based on tracing acoustic markers within the myocardium on standard two-dimensional (2D) images provides strain and rotation parameters, which overcomes the limitation of TDI and has proven to be valuable in evaluating cardiac function. 14 – 16 Investigations of AS and AR in tricuspid aortic valve (TAV) patients revealed abnormal strain and rotation values when compared with normal healthy controls. 8 , 13 Analysis of strain provides a powerful means of unmasking subtle myocardial dysfunction that is not detected by LVEF in early stages.…”

Aortic stenosis (AS) and aortic regurgitation (AR) are associated with congenital isolated bicuspid aortic valve (BAV) disease. The chronic pressure overload of AS and the volume overload of AR are known to impair the left ventricular function. This study assessed whether two-dimensional speckle tracking echocardiography (2D-STE) is capable of detecting the myocardial dysfunction associated with BAV caused by various aortic valve lesions in patients retaining normal ejection fraction (EF).Thirty-two isolated BAV patients and 20 healthy tricuspid aortic valve (TAV) volunteers were recruited. BAV patients were divided into 4 subgroups based on aortic valvular lesion types: normal function (NF) group, isolated AS group, isolated AR group, and a group who had both AS&AR. Myocardial strain and degree of twist were analyzed and compared between the BAV and TAV groups, as well as between valvular lesion groups and the NF group.Compared with healthy TAV controls, global radial strain (GRS), global circumferential strain (GCS), global longitudinal strain (GLS), and twist angle absolute values were lower in the BAV group (P < 0.05). The AS, AR, and AS&AR groups all demonstrated a significant decrease in GRS and GCS when compared with the TAV group. The AS and AS&AR groups demonstrated lower GLS than the TAV group, and the smallest degree of twist was detected in the AR group. There were no significant differences between the NF and TAV groups. The AR and AS&AR groups demonstrated significant differences in multiple parameters of cardiac mechanics compared with the NF group.2D-STE is able to detect altered cardiac mechanics associated with aortic lesion types in BAV patients with normal EF compared with normal TAV controls, and so can provide valuable information for clinical decision-making.

“…Zhu et al . [ 29 ] used 3D strain echocardiography for comparison of strain values with sonomicrometry (excellent echo-window quality by the use of an in vitro study). In this study the interobserver reproducibility of strain values was excellent (R 2 values using high frame rate were 0.86 for longitudinal strain and 0.86 for circumferential strain) based on the good image quality.…”

Objectives: Strain echocardiography (StE) promises to be a new tool for quantitative assessment of cardiac function. Analysis of intra- and interobserver reliability is an important aspect in the process of developing these novel techniques from theory to the implementation into daily routine diagnostics.The purpose of the study was to estimate reliability of the segmental StE.Methods: Left ventricular strain analysis for radial strain (RS), circumferential strain (CS) and longitudinal strain (LS) was performed in 21 healthy volunteers. RS and CS values were obtained in the parasternal short axis at the level of the papillary muscles. LS values were determined in the apical 2-, 3- and 4-chamber views. Cine-loops were recorded and quantitative analyses were conducted on an off-line workstation.Results: Intraobserver reproducibility was highest using LS in the 4-chamber view (9 ± 13.6 % mean deviation, rho = 0.624, p = 0.003), followed by CS (13.3 ± 8.3 %, rho = 0.406, p = 0.068) and lowest in RS (26.3 ± 30.1 %, rho = 0.391, p = 0.080). Interobserver analyses of LS derived from 3-chamber view showed lowest deviation (11.9 ± 9.5 %, rho = 0.513, p = 0.017), followed by CS (15.2 ± 12.0 %, 0.263, p = 0.249) and the least consistent measurements in RS (35.9 ± 46.3 %, rho 0.382, p = 0.088).Conclusion: This study shows that the clinical utility of StE depends on the regional differences of LV wall motion and image quality. LS-values showed promising intra- and interobserver reproducibility values. For quantitative follow-up studies LS should be preferred.

“…3DE images can be rotated and cropped, overcoming 2DE limitations by allowing for ideal VSD(s) view. 3DE is limited by low temporal resolution . Considering the potential of 3DE to be more accurate in assessing VSD size, implicating that it would lead to more effective and confidently made treatment decisions, a 2D/3DE comparison study simultaneously taking VSD number, size, and shape into account is needed and to our knowledge has yet to be performed.…”

Background Quantification of defect size and shunt flow is an important aspect of ventricular septal defect (VSD) evaluation. This study compared three‐dimensional echocardiography (3DE) with the current clinical standard two‐dimensional echocardiography (2DE) for quantifying defect area and tested the feasibility of real time 3D color Doppler echocardiography (RT3D‐CDE) for quantifying shunt volume of irregular shaped and multiple VSDs. Methods Latex balloons were sutured into the ventricles of 32 freshly harvested porcine hearts and were connected with tubing placed in septal perforations. Tubing was varied in area (0.13–5.22 cm²), number (1–3), and shape (circle, oval, crescent, triangle). A pulsatile pump was used to pump “blood” through the VSD (LV to RV) at stroke volumes of 30–70 mL with a stroke rate of 60 bpm. Two‐dimensional echocardiography (2DE), 3DE, and RT3D‐CDE images were acquired from the right side of the phantom. Results For circular VSDs, both 2DE and 3DE area measurements were consistent with the actual areas (R² = 0.98 vs 0.99). For noncircular/multiple VSDs, 3DE correlated with the actual area more closely than 2DE (R² = 0.99 vs 0.44). Shunt volumes obtained using RT3D‐CDE positively correlated with pumped stroke volumes (R² = 0.96). Conclusions Three‐dimensional echocardiography (3DE) is a feasible method for determining VSD area and is more accurate than 2DE for evaluating the area of multiple or noncircular VSDs. Real‐time 3D color Doppler echocardiography (RT3D‐CDE) is a feasible method for quantifying the shunt volume of multiple or noncircular VSDs.
