Abstract Background: A novel three-dimensional echocardiography (3DE)-derived strain analysis software specialized for right ventricular (RV) monitoring is emerging that could definitely evaluate RV free wall and interventricular septum longitudinal strain. The aim of this study was to compare the diagnostic performance in evaluating RV function between 3DE and two-dimensional echocardiography (2DE)-derived longitudinal strain.Methods: Echocardiographic examinations were performed in 82 patients with RV dysfunction associated with chronic left-sided heart failure and 40 control subjects. RV dysfunction was defined as a 3DE-derived RV ejection fraction (EF) <45%. Both 2DE and 3DE-derived strain analyses were performed in all the patients to measure the longitudinal strain of RV.Results: 3DE-derived peak systolic longitudinal strain of RV free wall (RV-fwLS) was significantly lower in patients with RV dysfunction compared to control subjects (-14.0±4.1 vs. -26.7±4.7%; p<0.001), and it correlated well with cardiac magnetic resonance-derived RVEF (r=0.74, p<0.001). On receiver operator characteristic analysis, a 3DE-derived RV-fwLS cutoff value of >-21.1% was most useful in identifying patients at higher risk of RV dysfunction (sensitivity: 90% and specificity: 85%), also higher than 2DE-derived strain parameters. Additionally, RV dysfunctional patients with pulmonary hypertension (PH) had significantly reduced 3DE-derived RV-fwLS value than the subgroup without PH (-13.1±3.8 vs. -15.0±4.2; p<0.05).Conclusion：Assessment of impaired RV systolic function by 3DE-derived longitudinal strain is better than 2DE in chronic left-sided heart failure patients with left ventricular EF <45%. 3DE-derived strain analysis specialized for RV should be considered as a complementary tool for assessing RV function.

Abstract Background The function of both ventricles have been suggested to be affected in patients with mitral stenosis. In this study, it was aimed to investigate deformation properties of right (RV) and left ventricles (LV) in mild and moderate rheumatic mitral stenosis (MS) patients with three-dimensional speckle tracking echocardiography (3D-STE). Methods A total of 60 patients were included in the study (20 patients with mild MS diagnosis, 20 patients with moderate MS diagnosis and 20 healthy volunteers). Three-dimensional echocardiography datasets were obtained for both ventricles in all patients. An example for RV assessment is shown in Figure 1. LV global longitudinal strain (GLS), LV torsion, RV free wall (FW) LS and interventricular septal (IVS) LS measurements were analyzed. Results The LV ejection fraction (EF), RV fractional area change and tricuspid annular plane systolic excursion values were statistically similar and in the normal range. The LV GLS measurements were significantly different among the groups by being highest in the control group and least in the moderate stenosis group (ANOVA,p &lt; 0.001) (Table 1). Patients with MS showed higher torsional values, correlated with MS severity (ANOVA,p &lt; 0.001) (Table 1). IVS LS, RVFW LS values obtained by RV analysis also differed significantly among groups. The FW-GLS values only showed significant difference between the control group and moderate MS group (Table 1). Conclusion Patients with mitral stenosis showed lower LV-GLS and higher LV torsion values. Although the LV GLS is affected; the LV EF was detected to be normal due to increase in LV torsion. RV deformation indices showed signıficant decrease in correlation with the severity of the mitral stenosis. In conclusion, our data suggest that subclinical LV and RV systolic dysfunction is present in mild-moderate MS patients and this dysfunction can be detected by 3D-STE.

Abstract Introduction Evaluation of right ventricular (RV) function is essential in the follow up of patients with arrhythmogenic right ventricular cardiomyopathy (ARVC). Role of advance echocardiography including 3D transthoracic echocardiography (3DTTE) for evaluation of 3D RV function and RV longitudinal strain in predicting prognosis in ARVC patients, has not been well investigated. Purpose We aimed to evaluate 3DTTE parameters in predicting major advance cardiovascular events (MACE) defined as ventricular arrhythmia, cardiac hospitalization, heart transplantation, and death in ARVC patients. Methods Forty-eight definite ARVC subjects based on the 2010 Task force criteria were evaluated with standard 2D transthoracic echocardiography (2DTTE) and 3DTTE. Patients with poor image quality were excluded. RV function was evaluated by 2D and 3D TTE including: fractional area change (FAC), RV global and free wall longitudinal strain (RV2DGLS and RV2DFWLS) and 3D RV ejection fraction (RV3DEF), RV global and free wall longitudinal strain (RV3DGLS, and RV3DFWLS). The patients were followed up for a median period of 12 months (6–18 months) to record MACE. Results Forty-eight patients with mean age =38.5±14 years; 79.2% male, and mean RV3DEF =30.33%, were included. During the mean follow up 12 months, 12 patients (25%, with mean RV3DEF = 24.8±9%) experienced MACE whereas mean RV3EF in patient without any cardiovascular events during follow up was 34.21±9%. The most common causes of hospitalization were arrhythmia, right-sided heart failure, and RV clot as the following: Ventricular arrhythmia in 7 patients (14.6%, with mean RV3DEF = 29.01±8.82%), RV clot in 2 cases (4.2%, with mean RV3DEF = 20.2%), right-sided heart failure in 3 patients (6.3%, with mean RV3DEF = 16.83±3.6%) that 2 of them (2.1%, with mean RV3DEF = 14.58±0.63) underwent heart transplantation. Logistic regression analysis revealed RV3DTTE (p-value = 0.03, OR=0.90, CI: 0.82–0.99), RV3DGLS (p-value = 0.05, OR=1.27, CI: 0.99–1.61) and RV3DFWLS (p-value = 0.01, OR=1.29, CI: 1.05–1.59), predicted cardiac adverse events, but there were no significant association between RV2DGLS, RV2DEWLS and FAC with MACE. Conclusion RV3DEF, RV3DGLS, and RV3DFWLS were powerful predictors of morbidity and mortality and can be useful as a valuable method in the prediction of major cardiovascular complications in ARVC patients.

Abstract Background—The changes in cardiac function that occur after pericardiocentesis are unclear.Purpose—This study was performed to assess right ventricular (RV) and left ventricular (LV) function with echocardiography before and after pericardiocentesis. Method and Results—In total, 19 consecutive patients who underwent pericardiocentesis for more than moderate pericardial effusion were prospectively enrolled from August 2015 to October 2017. Comprehensive transthoracic echocardiography was performed before, immediately after (within 3 hours), and 1 day after pericardiocentesis to investigate the changes in RV and LV function. RV dysfunction is defined as meeting three of the four criteria: a TAPSE of &lt;17 mm, an S’ of &lt;9.5 cm, an FAC of &lt;35%, and an RV free wall longitudinal strain &gt;−20%. The mean age of all patients was 72.6 ± 12.2 years. The changes of echocardiographic parameters related to RV function are shown in Table. After pericardiocentesis, RV inflow and outflow diameters increased and the parameters of RV function significantly decreased. These abnormal values or RV dysfunction remained at 1 day after pericardiocentesis. Conversely, no parameters of LV function parameters changed after pericardiocentesis. Of 19 patients, 13 patients showed RV dysfunction immediately after pericardiocentesis and 6 patients did not. RV free wall longitudinal strain before pericardiocentesis was higher in patients with post-procedural RV dysfunction (−18.9 ± 3.6%) than in those without (−28.4 ± 6.3%). ROC analysis revealed that a RV free wall longitudinal strain cut-off value of −23.0% had a sensitivity of 100% and a specificity of 83.3% for predicting the occurrence of RV dysfunction after pericardiocentesis (AUC = 0.910). Conclusions—The occurrence of RV dysfunction after pericardiocentesis should be given more attention. Pre-existing RV dysfunction maybe related to the occurrence of RV dysfunction after pericardiocentesis.

AbstractBackgroundIn CHD, three-dimensional strain analysis may overcome limitations of Doppler and two-dimensional strain of the left ventricle. The aims of this study were to evaluate feasibility and reproducibility of three-dimensional longitudinal, circumferential, and radial systolic strain by three-dimensional speckle-tracking echocardiography compared with two-dimensional echocardiography.MethodsPatients with CHD, biventricular circulation with a systemic left ventricle, and who had two- and three-dimensional imaging performed on the same day from 2010 to 2014 were included. Quantitative two- and three-dimensional strain analyses were performed (two-dimensional cardiac performance analysis version 1.2 and four-dimensional left ventricular analysis version 3.1). Intra- and inter-observer variabilities were calculated on 25 studies.ResultsA total of 30 patients, including 19 (61%) males, with a median age of 3.6 years (0.1–22 years) were included. The mean fractional shortening was 34.6±5.3%, and the mean ejection fraction was 62.0±6.4%. Measurement of two- and three-dimensional strain was feasible in >95% of segments. Good correlation was observed between longitudinal and circumferential strain (r=0.92, p⩽0.001 and r=0.87, p⩽0.001), but not radial strain (r=0.29, p=0.2). Intra- and inter-observer agreements were better for three-dimensional compared with two-dimensional strain, and better for both two- and three-dimensional longitudinal and circumferential strains compared with radial strain.ConclusionLeft ventricular three-dimensional strain analysis is feasible in children with CHD. The reproducibility of longitudinal and circumferential strain by three-dimensional analyses is better. Further longitudinal studies are warranted for the potential clinical application of this new technology.
