Abstract Purpose The purpose of this study was to examine right ventricular (RV) function by three-dimensional speckle-tracking echocardiography (3DSTE) in patients after correction of tetralogy of Fallot (TF), the accuracy of 3DSTE compared to cardiovascular magnetic resonance (CMR) findings and assess pulmonary arterial (PA) distensibility in order to achieve a more comprehensive understanding of the matching between RV performance and PA load. Methods Twenty-one patients (mean age 39 ± 16 years) with repaired TF and twenty-one age-matched healthy subjects selected as controls were studied. CMR findings were available in 14 patients. RV volumes, RV ejection fraction (RVEF) and RV longitudinal and circumferential strains were calculated by three-dimensional echocardiography and three-dimensional speckle tracking echocardiography. The main pulmonary artery was interrogated by color, pulsed, and continuous-wave Doppler. Pulmonary regurgitation (PR) was assessed by color-flow mapping and graded as none, mild, or greater than mild using the measurement of the regurgitant jet width in relation to the outflow tract diameter. Right pulmonary artery (PA) was visualized from suprasternal view by two-dimensional echocardiography. Tissue Doppler Imaging (TDI) mode was activated in B-mode imaging to examine arterial motion, then mode was changed to color-mode with the beam line aligned perpendicular to the superior and inferior walls of the right PA. PA distensibility and strain were determined. Data analysis was performed offline. Results Overall, 3D RVEF and RV longitudinal strain were reduced in TF patients compared to the control group. Nine patients had moderate or moderate-to-severe PR. PA strain and distensibility were decreased (p = 0.003) compared with controls, both in the presence and absence of PR. PA strain had a positive correlation with RVEF (r = 0.79, p < 0.005) and RV strain (r = 0.82, p < 0.001). RV end-diastolic and end-systolic volumes by 3DE correlated with the respective parameters by CMR (r = 0.88,p < 0.001 and r = 0.87,p < 0.005 respectively). Patients with moderate-to-severe PR had more prominent PA strain changes (p = 0.02). Conclusions Three-dimensional right ventricular ejection fraction and RV strain are impaired in patients with repaired TF, in agreement with CMR data. Reduced PA strain is associated with reduced RV 3DSTE parameters and is more pronounced in the presence of pulmonary regurgitation.

BackgroundWe sought to investigate right ventricular (RV) function and deformation assessed by three-dimensional echocardiography (3DE) and speckle tracking in patients with subclinical hypothyroidism (SHT), and to evaluate the influence of levothyroxine (l-T4) therapy on RV remodeling.MethodsWe included 50 untreated women with SHT and 45 healthy control women matched by age. Thel-T4therapy was prescribed to all SHT patients who were followed 1 year after euthyroid status was achieved. All study participants underwent laboratory analyses which included thyroid hormone levels, and complete two-dimensional echocardiography (2DE) and 3DE examinations.Results3DE RV end-diastolic volume and ejection fraction were significantly reduced in the SHT patients before therapy in comparison with the healthy controls and treated SHT subjects. RV longitudinal strain, systolic, and early diastolic strain rates (SRs) were significantly decreased, whereas RV late diastolic SR was increased in the SHT patients before therapy when comparing with the controls. 2DE speckle tracking imaging revealed thatl-T4substitution therapy significantly improved RV systolic mechanics, whereas RV diastolic deformation was not completely recovered. Right atrial (RA) function and deformation were significantly impacted by SHT. Replacementl-T4treatment improved but did not completely restore RA mechanics in the SHT patients.ConclusionRV and RA function and mechanics are significantly affected by SHT.l-T4therapy and 1-year maintenance of euthyroid status improved but did not completely recover RV and RA function and deformation in the SHT patients, which implies that right heart remodeling caused by SHT is not reversible in a 1-year period.

Background: Right ventricular (RV) function is an important determinant of outcomes in pulmonary hypertension (PH) patients. Conventional indices of fractional area change (FAC), tricuspid annular plane systolic excursion (TAPSE), and RV tissue Doppler imaging myocardial performance index (RV TDI MPI) have been used as surrogates of RV function. RV ejection fraction (EF) from real time three-dimensional echocardiography (RT-3DE) has emerged as a quantitative evaluation of global RV function and has correlated well with cardiac magnetic resonance imaging. In this study, 3D RV EF was compared with conventional indices in the serial evaluation of RV function in pediatric PH patients to predict adverse events. Methods: Forty-eight pediatric PH patients (median age = 10 years (4 months - 27 years)) were evaluated serially (138 visits with median interval visit = 116 days (4 -368 days)) with RT-3DE to follow their ejection fraction (EF) and conventional indices from April, 2014 to May, 2015. Echocardiographic variables include measures of RV function: 3D RV EF, FAC, TAPSE, and RV TDI MPI. Adverse events included: initiation or intensification of intravenous vasodilator therapy, atrial septostomy, Pott’s shunt, or death. Receiver Operating Characteristics (ROC) analyses were performed to identify the best cut-offs in predicting adverse events in serial follow up of pediatric PH patients. Results: Patients were classified based on their World Health Classification (I = 16, II=16, III=11, IV=3). Two patients were not classified as they were too young. There were 13 adverse events. 3D RV EF was a good predictor of adverse events with highest area under curve (AUC) = 0.79, p<0.001(cut-off value of 38% = sensitivity 69%; specificity of 78%) compared to FAC has an AUC = 0.77, p<0.05 (cut-off value of 33% = sensitivity 63%; specificity of 78%). TAPSE and TV TDI MPI were not statistically significant (AUC = 0.54, p = 0.65; AUC 0.63, p = 0.09 respectively). Conclusion: 3D RV EF is a good index in predicting adverse events and was better than FAC, TAPSE, and RV TDI MPI in predicting adverse events in serial follow up of pediatric PH patients. 3D RV EF can be used as a noninvasive tool in the serial evaluation of RV function in pediatric PH patients as it is easily obtained clinically.

AbsractThe structural complexity of the right ventricle has made quantitative evaluation difficult. Conventional cross-sectional echocardiographic methods are limited by geometric assumptions and the position of the planes used for imaging. Previous reports have demonstrated accurate three-dimensional echocardiographic quantitation of the right ventricle in-vitro and in experimental animals. We adapted a previously described method for three-dimensional reconstruction of the left ventricle to compute right ventricular volume and ejection fraction in a clinical setting.We examined 29 patients aged from 2 to 42 years with pulmonary hypertension, by three-dimensional echocardiography and resonance imaging. Correlation and agreement were calculated for volumes and ejection fractions. Three-dimensional echocardiographic reconstruction, when compared to resonance imaging, yielded r values of 0.95 and 0.93, and mean differences (bias) of 31% ± 19% and 33% ± 18%, for systolic and diastolic volumes respectively. Interobserver variability was low (12.9% and 8.0%). Ejection fraction as calculated by three-dimensional echocardiography showed close agreement with resonance images (bias=l% ±7%). Three dimensional echocardiography is now a method of measuring right ventricular ejection fraction in the clinical setting which produces results comparable to those of resonance imaging. Volume measurements correlated well for systole and diastole, but consistently underestimated values produced from resonance images.
