“…Strain estimation is highly dependent on the echocardiography equipment and methodology used, and variations in these can result in significant changes. The same equipment was always used in the present study, following recommended reference guidelines 8,[10][11][12][13]15,27 . A decision was taken to consider the LS rather than the global strain due to the high proportion of patients undergoing left surgery, allowing a more specific assessment of RV function.…”

“…It can be readily and reproducibly measured by echocardiography but assesses only a single part of the RV and is dependent on the preload, and both shortcomings are also shared by the tissue Doppler-derived S' wave and shortening fraction (SF) [6][7][8][9][10][11] . These limitations have been overcome in part by the development of myocardial deformation techniques that assess more segments and are less preload-dependent [12][13][14][15][16][17][18] .…”

Evaluation of right ventricular (RV) function after tricuspid valve surgery is complex. The objective was to identify the most appropriate RV function parameters for this purpose. This prospective study included 70 patients undergoing cardiac and tricuspid valve (TV) surgery. RV size and function parameters were determined at 3 months and 1-year post-surgery. Categorical variables were analyzed with the McNemar test and numerical variables with the Student’s t-test for related samples or, when non-normally distributed, the Wilcoxon test. Spearman's rho was used to determine correlations between variables at 3 months and 1 year. RV diameters were reduced at 3 months post-surgery and were then unchanged at 1 year. Tricuspid annular plane systolic excursion (TAPSE) and S′ wave values were worse at 3 months and then improved at 1 year (t-score-2.35, p 0.023; t-score-2.68; p 0.010). There was no significant reduction in free wall longitudinal strain (LS) or shortening fraction (SF) at 3 months (t-score 1.421 and − 1.251; p 0.218 and 0.172), and they were only slightly below pre-surgical values at 1 year. No relationship was found between RV function parameters and mortality or major complications. During the first few months after TV surgery, LS may be a more appropriate parameter to evaluate global ventricular function in comparison to TAPSE. At 1 year, good correlations are observed between TAPSE, S′ wave, and LS values.

PurposeThe presence of right ventricular dysfunction indicates a higher risk status in patients with pulmonary embolism (PE). The RV strain evaluated by speckle‐tracking echocardiography seems to be more reliable method in the evaluation of RV dysfunction as compared to standard echocardiographic measures. In this study, we aimed to determine the value of myocardial‐work indices in evaluating serial changes of RV function in acute PE.MethodsOur study comprised 83 consecutive acute PE patients who admitted to our tertiary cardiovascular hospital. Echocardiography was performed within the first 24‐hours of hospitalization, and RV and LV myocardial‐work parameters were obtained along with standard echocardiographic parameters. The change in the RV/LVr detected on tomography was selected as the primary outcome measure, and its' predictors were analyzed with classical linear regression and a generalized additive model (GAM).ResultsAmong the LV‐RV strain and myocardial work parameters, the RV global longitudinal strain (GLS) has borderline statistical significance in predicting the RV/LVr change whereas the RV global work efficiency (RV‐GWE) strongly predicted RV/LVr change (p: 0.049 and <0.001, respectively).ConclusionIn this study, classical linear regression and GAM analyses showed that RV‐GWE seems to offer a better prediction of RV/LVr change in patients with acute PE.

Purpose of Review The right ventricle (RV) has a complex geometry and physiology which is distinct from the left. RV dysfunction and failure can be the aftermath of volume- and/or pressure-loading conditions, as well as myocardial and pericardial diseases. Recent Findings Echocardiography, magnetic resonance imaging and right heart catheterisation can assess RV function by using several qualitative and quantitative parameters. In pulmonary hypertension (PH) in particular, RV function can be impaired and is related to survival. Summary An accurate assessment of RV function is crucial for the early diagnosis and management of these patients. This review focuses on the different modalities and indices used for the evaluation of RV function with an emphasis on PH.
