NORMAL VALUES FOR RIGHT VENTRICULAR SIZE AND FUNCTION USING THE RIGHT VENTRICLE-FOCUSED VIEW ON ECHOCARDIOGRAPHY

Abstract Purpose To investigate the relationship between right atrial deformation and the right ventricular size and function. Methods 94 patients with various cardiovascular pathologies have been included in the study group. All patients underwent transthoracic echocardiography with subsequent off-line analysis using speckle tracking technique and measurement of numerous right atrial deformation parameters, including peak atrial longitudinal strain (PALS) and peak atrial contraction strain (PACS), as well as established indices of right ventricular size and function, including right ventricular basal diameter in apical four-chamber view (RVITd), tricuspid annular peak systolic excursion (TAPSE) and global longitudinal strain (GLS). Results There was a statistically significant weak correlation between RA strain (PACS and PALS) and RV parameters. RV-GLS showed significant correlation with PALS (r = -0,38; p = 0,0015) and PACS (r = - 0,30; p = 0,013). Similarly, TAPSE correlated with PALS and PACS (r = 0,34; p = 0,02) and (r = 0,23; p = 0,04) respectively. However, there was no correlation between right atrial function and RVIT. Conclusions Right atrial deformation parameters weakly correlate with right ventricular function indices and show no correlation with the size of the right ventricle.

And Function

The right ventricle has lost its designation as the ‘forgotten ventricle’ over the past decade. Clinicians recognize its prognostic significance in a wide array of disease processes and imagers are now providing an assessment of right ventricular size and function in most studies. Despite this recognition, imaging the right heart presents numerous challenges to the imager. The shape of the chamber, the unique structure, and its coupling to the pulmonary circulation mandate a different approach to its evaluation as compared to the left ventricle. Imaging may be done by several modalities, each with their own strengths and limitations. Even more so than with the left ventricle, the findings must be interpreted in the context of loading conditions and clinical setting. This chapter will focus on the two main right heart imaging modalities—echocardiography and cardiac MRI.
