“…Although other methods of RV function, such as global or free-wall strain, have been used by other groups, TAPSE is frequently used secondary to time and software constraints. 15, 16 We recognize other efforts to use strain to describe RV function, but in the perioperative setting, methods to quickly quantify RV function are important during serial evaluation of the heart, particularly when using intraoperative TEE imaging to monitor and guide treatment. Although strain may provide additional information and may be more accurate regarding RV function, in the perioperative period without direction on how to adjust perioperative management on the basis of strain findings, strain was not included in this evaluation.…”

“…Although strain may provide additional information and may be more accurate regarding RV function, in the perioperative period without direction on how to adjust perioperative management on the basis of strain findings, strain was not included in this evaluation. 15,16 Quantifying RV function during TEE imaging, which correlates well with TTE M-mode imaging, could be useful when comparing RV function in various perioperative situations, including separation from cardiopulmonary bypass, performing serial evaluations during left ventricular assist device placement, and following patients with some component of RV dysfunction in the intensive care unit. 17 Therefore, the focus of this investigation on M-mode and STE TAPSE is intended to elucidate the poor reliability of M-mode TAPSE during TEE imaging and provide a simple, quick replacement in the form of STE TAPSE.…”

“…Our reference values are close to the data reported by Meris et al 22 from 100 subjects (free wall RVLS, −28.7%). In 142 multiethnic normal subjects, Chia et al 21 found a free wall RVLS value of −27.3%. In both studies, a different scanner (Vivid 7) and a presumably earlier EchoPac software version (not specified) were used, which may have accounted for minor interstudy differences in reference values, as observed from the studies reporting the reference values of LV 2DSTE strain.…”

Accordingly, in this prospective study, we aimed to (1) assess the presence and extent of measurement variability in relation to the various methods and definitions of RVLS, Background-Despite the fact that assessment of right ventricular longitudinal strain (RVLS) carries important implications for patient diagnosis, prognosis, and treatment, its implementation in clinical settings has been hampered by the limited reference values and the lack of uniformity in software, method, and definition used for measuring RVLS. Accordingly, this study was designed to establish (1) the reference values for RVLS by 2-dimensional speckle-tracking echocardiography; and (2) their relationship with demographic, hemodynamic, and cardiac factors. Methods and Results-In 276 healthy volunteers (55% women; age, 18-76 years), free wall and septum RVLS (6 segments) and free wall RVLS (3 segments) using both 6-and 3-segment regions of interest were obtained. Feasibility of 6-segment RVLS was 92%. Free wall RVLS from 3-versus 6-segment regions of interest had similar values, yet 6-segment region of interest was more feasible (86% versus 73%; P<0.001) and reproducible. Reference values (lower limits of normality) were as follows: 6-segment RVLS, −24.7±2.6% (−20.0%) for men and −26.7±3.1% (−20.3%) for women; 3-segment RVLS, −29.3±3.4% (−22.5%) for men and −31.6±4.0% (−23.3%) for women (P<0.001). Free wall RVLS was 5±2 strain units (%) larger in magnitude than 6-segment RVLS, 10±4% larger than septal RVLS, and 2±4% larger in women than in men (P<0.001). At multivariable analysis, age, sex, pulmonary systolic pressure, right atrial minimal volume, as well as right atrial and left ventricular longitudinal strain resulted as correlates of RVLS values. Conclusions-This is the largest study providing sex-and method-specific reference values for RVLS. Our data may foster the implementation of 2-dimensional speckle-tracking echocardiography-derived RV analysis in clinical practice.(Circ Cardiovasc Imaging. 2016;9:e003866.

“…These factors may be considered as the earliest predictors of decreasing functional capacity. According to the close correlation of wedge pressure and right ventricular pressure to the preload and afterload of the pulmonary circulation system [22], we focused on the impact of RV strain in patients with upper limit of estimated left atrial pressure (E/e’). Interestingly, in these groups, the discriminative power of RVLS_FW increased significantly.…”

BackgroundRight ventricular (RV) function has been found to be a major factor of exercise capacity in patients with heart failure. However, the role of RV function in exercise capacity in healthy subjects has not been well studied. This study aims to validate the role of RV strain derived from speckle tracking echocardiography for exercise capacity for health check-up subjects.MethodsThis study prospectively recruited subjects from a routine health examination. All of them were symptom free. RV function represented by RV strain was derived from speckle tracking echocardiography in addition to traditional echocardiography parameters. Functional capacity was determined by a symptom limited treadmill exercise test with the Bruce protocol.ResultsAmong 164 recruited subjects (age 52.2 ±9.2 years, 66.4% male), 32 subjects represented impaired functional capacity (MET<8), which was significantly correlated with age, left ventricular mass index, left ventricular filling pressure (E/e’), global longitudinal strain of the left ventricle (LVGLS) (-16.0±2.5% vs. -18.9±3.8%, p < 0.001) and RV free wall strain (RVLS_FW) (-17.0±4.9% vs. -21.9±3.2%, p <0.001). After multivariate logistic regression, RVS_FW was an independent predictor for impaired functional capacity (OR 1.62, CI 1.32–1.98; p <0.001).ConclusionsIn conclusion, RV strain is independently associated with exercise capacity for health check-up subjects. RV function is an important factor for functional capacity.
