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 < 0.001) (Table 1). Patients with MS showed higher torsional values, correlated with MS severity (ANOVA,p < 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 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.
