“…RV speckle tracking echocardiography (STE) is a novel method that allows quantitative assessment of RV function. Utility of RV STE both as a diagnostic and prognostic tool has been shown in various disease entities, including pulmonary hypertension (PH) [11], congenital heart disease [12], [13], heart failure [14] and cardiomyopathies [15].…”

AimsThis study sought to characterize global and regional right ventricular (RV) myocardial function in patients with Takotsubo cardiomyopathy (TC) using 2D strain imaging.MethodsWe compared various parameters of RV and left ventricular (LV) systolic function between 2 groups of consecutive patients with TC at initial presentation and upon follow-up. Group 1 had RV involvement and group 2 did not have RV involvement.ResultsAt initial presentation, RV peak systolic longitudinal strain (RVPSS) and RV fractional area change (RVFAC) were significantly lower in group 1 (−13.2±8.6% vs. −21.8±5.4%, p = 0.001; 30.7±9.3% vs. 43.5±6.3%, p = 0.001) and improved significantly upon follow-up. Tricuspid annular plane systolic excursion (TAPSE) did not differ significantly at initial presentation between both groups (14.8±4.1 mm vs. 17.9±3.5 mm, p = 0.050). Differences in regional systolic RV strain were only observed in the mid and apical segments. LV ejection fraction (LVEF) and LV global strain were significantly lower in group 1 (36±8% vs. 46±10%, p = 0.006 and −5.5±4.8% vs. −10.2±6.2%, p = 0.040) at initial presentation. None of the parameters were significantly different between the 2 groups upon follow-up. A RVPSS cut-off value of >−19.1% had a sensitivity of 85% and a specificity of 71% to discriminate between the 2 groups.ConclusionIn TC, RVFAC, RVPSS, LVEF and LV global strain differed significantly between patients with and without RV dysfunction, whereas TAPSE did not. 2 D strain imaging was feasible for the assessment of RV dysfunction in TC and could discriminate between patients with and without RV involvement in a clinically meaningful way.

“…In fact, despite preserved TAPSE, in the present study, impaired RVFWS was associated with a 3-fold increase in the risk of events, which remained significant after adjusting for clinical and echocardiographic confounders. Because it has been demonstrated a close negative correlation between RV longitudinal strain and RV stroke work index, 31 which represents the hemodynamic parameter usually used to evaluate RV function in patients waiting for heart transplant, RV longitudinal strain seems a reliable method for the assessment of RV function.…”

“…Therefore, the cutoff value of −15.3% for RVFWS needs to be further tested in larger HF studies. There is no consensus about which RV strain parameter should be used in clinical practice: we used freewall longitudinal strain instead of global RV strain because it demonstrated the highest diagnostic accuracy to predict a depressed RV stroke work index in a simultaneous echocardiographic-catheterization study, 31 suggesting that the free wall might better reflect function of RV than global RV strain.…”

Background-In heart failure (HF) with reduced ejection fraction, right ventricular (RV) impairment, as defined by reduced tricuspid annular plane systolic excursion, is a predictor of poor outcome. However, peak longitudinal strain of RV free wall (RVFWS) has been recently proposed as a more accurate and sensitive tool to evaluate RV function. Accordingly, we investigated whether RVFWS could help refine prognosis of patients with HF with reduced ejection fraction in whom tricuspid annular plane systolic excursion is still preserved. Methods and Results-A total of 200 patients with HF with reduced ejection fraction (age, 66±11 years; ejection fraction, 30±7%) with preserved tricuspid annular plane systolic excursion (>16 mm) underwent RV function assessment using speckle-tracking echocardiography to measure peak RVFWS.

“…R ight ventricular (RV) systolic function is an important prognostic factor in heart failure (HF) with longitudinal systolic amplitude of motion and myocardial strain predicting exercise capacity and survival (1)(2)(3)(4). Such measurements of RV free wall have proved essential in contributing to 80% of its stroke volume and are able to explain the cavity adaptive mechanisms to volume and pressure overload (5).…”
