: OBJECTIVES: Between 10% and 40% of patients who receive a left ventricular assistance device (LVAD) suffer from right ventricular failure (RVF) shortly after the device is implanted. Patients with post-LVAD RVF tend to have poor outcomes. Only a few predictive factors concerning the right ventricle (RV) have been investigated. Our goal was to search for non-invasive variables that correlate with RV function, focusing on echocardiographic parameters of the RV.METHODS: We selected 3 parameters: tricuspid annular plane systolic excursion, right ventricular fractional area change and right ventricular global longitudinal strain. We searched the literature and pooled relevant studies in a meta-analysis. Finally, we performed a statistical analysis to confirm whether each parameter was a reliable predictor of RVF after LVAD implantation.RESULTS: We retained 19 articles involving a total of 1561 patients. We found a pooled standardized mean deviation of −0.13 cm for the tricuspid annular plane systolic excursion, with the lower and upper tails of −0.21 and −0.04 cm, respectively. Concerning the right ventricular fractional area change, the averaged standardized mean deviation was equal to −2.61%, with the lower and upper extremities of −4.12% and −1.09%, respectively. Finally, regarding the global longitudinal strain, the standardized mean deviation was equal to −2.06% with an uncertainty value between −3.23% and −0.88%.CONCLUSIONS: The tricuspid annular plane systolic excursion could be a reliable parameter in RVF prediction. The right ventricular fractional area change and global longitudinal strain are likely to be stronger predictors of RVF after LVAD implantation. Prospective studies should be carried out to confirm this observation.
