Introduction: Strain determination by speckle-tracking analysis has been used worldwide in determining strain in the left ventricle. However, strain determination using speckle-tracking analysis can also be done for the right ventricle. This study aimed to establish the normative data on the right ventricular lateral free wall (RVLFW) strain in healthy Filipino adults. Methodology: This was a pilot cross-sectional descriptive study on healthy adult Filipinos seen at the St. Luke’s Medical Center−Global City from April 2015 to February 2016. Subjects underwent 2D echocardiography with speckle-tracking analysis. Strain values from the RVLFW segments were calculated using speckle-tracking analysis software. Tricuspid annular plane systolic excursion (TAPSE) was calculated according to American Society of Echocardiography guidelines. Peak systolic velocity at the lateral tricuspid annulus (Sm’) was obtained from pulsed Doppler. Mean RVLFW values were computed and correlated with Sm’ and TAPSE using Pearson’s correlation. Results: Of the 432 patients initially screened, 66 were included in this study. The mean age was 39±9 years, with male patients comprising 53% of the study population. The mean left ventricular ejection fraction was 65±4.2% The mean TAPSE was 2.1±0.32 cm and the mean Sm’ was 11.6±1.9 cm/s. The speckle-tracking analysis of the RVLFW showed a mean strain of −19.1±6.0% for the basal segment. The mid segment had a mean strain of −26.8± 6.9%, while the apical segment had a mean strain of −26.2±6.4%. The entire lateral free wall had a mean strain of −24.0±4.5%. Females had a significantly higher RVLFW strain value than males. The RVLFW strain was not significantly correlated with TAPSE and Sm’. However, TAPSE was significantly correlated with apical lateral strain (r=0.286; r2=0.082). However, the strength of correlation with the apical lateral strain was weak , explaining only about 8.2% of the variability of apical lateral strain. Conclusion: This study showed that the mean RVLFW strain in healthy adult Filipinos was −24.0±4.5% (95% CI −22.9% to −25.1%). Furthermore, RVLFW strain in healthy adult Filipinos was not significantly correlated with TAPSE and Sm’.
