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.

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.

Abstract Background Chronic heavy cigarette smoking can affect the right ventriclular function. The standard echocardiography may not show early right ventricular functional changes, and a more sensitive measure is needed. The aim of this work was to evaluate the subtle subclinical effects of chronic heavy cigarette smoking on the right ventricular function. The study included 55 healthy asymptomatic chronic heavy cigarette smokers (smoking history of at least 5 pack-years and a daily cigarette consumption of at least 1 pack) and 35 healthy non-smoking control subjects. Patients underwent a full clinical assessment and a conventional as well as a 2D-speckle tracking transthoracic echocardiography of the right ventricle and data was compared between the 2 groups. Results The mean age was 32.9 ± 7.2 years in smokers and 30.9 ± 7.9 years in non-smokers (p = 0.227). The 2 groups showed comparable conventional right ventricular systolic and diastolic functions. Smokers showed a significantly lower (less negative) right ventricular global longitudinal strain (− 19.0 ± 3.2% vs. − 24.5 ± 3.5%, p < 0.001). Patients with a higher daily cigarette consumption showed a poorer right ventricular global longitudinal strain (p = 0.014). Conclusion Chronic heavy cigarette smoking can adversely affect the right ventricular function, a finding that can be easily missed by conventional echocardiography and can be better detected by the right ventricular speckle tracking.
