Background: Cardiac strain is a dimensionless measure of myocardial deformation. There are two parameters that can be assessed with the right ventricle (RV) strain software the RV free wall longitudinal strain (RVFWS) and the RV global longitudinal strain (RVGLS). The recent studies are recommending RV strain as a reliable marker of RV systolic and diastolic function. Methods: In this review article, we searched for new publications in the last 10 years from peer reviewed journals related to RV strain. The findings of these studies are summarised. Result: Seven studies proved the reliability of RV longitudinal strain as a reliable predictor of RV function compared to the TAPSE, RV fraction area change and RV EF, E/A ratio and tissue Doppler. Patients with reduction in RV longitudinal strain have high VIS score and worse postoperative outcome. Conclusion: Right ventricular strain is a reliable and better marker of RV function. The reduction in RV GLS and free wall strain are predictors of high inotropes and vasopressors requirement; and increase in postoperative morbidity and mortality after cardiac surgery.
