“…A systolic annular velocity \11.5 cm s -1 predicted right ventricular dysfunction (ejection fraction \45%) with a sensitivity of 90% and a specificity of 85% [79]. RV peak systolic velocity impairment has been observed in patients with scleroderma, obstructive sleep apnea syndrome, and LV failure [80][81][82][83][84]. Moreover, noninvasive estimation of right atrial pressure is possible [67,69] using trans-tricuspid pulsed-wave Doppler and TDI (E/E a ).…”

RV performance is difficult to evaluate, given its geometry, interrelationship with the left ventricle, and sensitivity to alterations in pulmonary pressure. This article focuses on some of the challenges related to the assessment of RV function in the setting of the RV's unique anatomic, physiologic, conventional and newer echocardiographic aspects, and therapeutic implications. The majority of proposed methods of echocardiographic assessment of RV function are based on volumetric approximations of the RV. Such approaches have inherent limitations, first as volume-related measures such as EF are load dependent, second because of the complex geometry of the RV. The issue of RV geometry is usually overcome using geometry-independent parameters such as tricuspid annular excursion and the Tei index. The recent introduction of real-time three-dimensional echocardiography and myocardial imaging echocardiography (tissue Doppler imaging, 1D-strain and 2D-strain echocardiography) implied a great progress in echocardiography. Tissue Doppler imaging allows the quantitative assessment of RV systolic and diastolic function by means of measurement of myocardial velocities. Strain measurements have been shown to correlate well with sonomicrometry segment length measurements both in the inflow and outflow tract of the RV and under different loading conditions. Other findings have been reported in chronic and acute clinical settings. Standard and novel echocardiographic methods of assessment of RV size and performance can help clinicians in the treatment of acute and chronic RV failure and contribute to a better understanding of the peculiar chamber-related functional mechanisms in the context of ventricular interdependent independency.

“…1c). MPI is one of the most accurate indices of ventricular performance since it includes parameters relative to both cardiac contraction and relaxation [19,20]. Moreover, MPI estimation based on tissue Doppler analysis is relatively independent from intravascular volume reduction after HD [23].…”

“…Regional TDI myocardial performance index (MPI) was calculated as previously reported [20]. Average regional TDI MPI for the right ventricle was calculated as follows: (MPI lateral + MPI septal )/2 [19]. RVD was defined by an average regional MPI value >2 SD from the mean of the values derived from a group of 100 healthy subjects (MPI >0.53).…”

“…Early (E) and late (A) right ventricular inflow velocities were measured with pulse-wave Doppler by placing the sample volume in between the tips of the tricuspid valve in the apical 4-chamber window. The TDI spectral signal was acquired from the apical 4-chamber view, with the sample volume placed along the lateral and septal tricuspid annulus [19]. Sm (systolic myocardial velocity), Em (protodiastolic myocardial velocity) and late peak diastolic myocardial velocity (Am) were measured.…”

Background: While chronic dialysis treatment has been suggested to increase pulmonary pressure values, right ventricular dysfunction (RVD) is a major cause of death in patients with end-stage renal disease. We investigated the impact of different dialysis treatments on right ventricular function. Methods: We examined 220 subjects grouped as follows: healthy controls (n = 100), peritoneal dialysis (PD; n = 26), hemodialysis (HD) with radial arteriovenous fistula (AVF; n = 62), and HD with brachial AVF (n = 32). Echocardiography including tissue Doppler imaging (TDI) of the right ventricle was performed in all patients. Results: Pulmonary pressure values progressively rose from controls across the 3 dialysis groups (21.7 ± 6.8, 29.7 ± 6.7, 37.9 ± 6.7 and 40.8 ± 6.6 mm Hg, respectively; p < 0.001). TDI indices of right ventricular function were more impaired in HD patients, particularly in those with brachial AVF. RVD, assessed by TDI myocardial performance index, was higher in HD patients compared with PD patients (71.3 vs. 34.6%, p < 0.001). Moreover, the prevalence of RVD further increased in patients with brachial AVF compared with the radial access (90.6 vs. 61.3%, p < 0.001). Conclusions: Compared to DP, HD increases the risk of RVD, particularly in the presence of brachial AVF. TDI may detect early functional failure of the right ventricle in HD patients.

“…The observation of the trend towards smaller hypertrophy in the Conventional group may reflect the difficulty in preparing mature myocardium in clinical practice, as well as the need for longer periods of stimulation to achieve that end. Although magnetic resonance imaging is currently the standard for morphological and functional assessment of RV 36,37 , in this study, we could not rely on such examination, which would certainly enrich the findings. Despite this, RV function was estimated by the same observer (MCDA), using the same method for all animals, which minimizes the variability between the two diagnostic approaches.…”
