Background
The main focus of most of the studies in heart failure (HF) is the assessment of the left ventricular functions, while the right ventricle was much less studied. Much of this neglect is due to the complexity of anatomy and physiology of the right ventricle which are considered challenges during assessment of RV.

BACKGROUND
Tricuspid annular plane systolic excursion (TAPSE) has become a popular tool for assessing right ventricular (RV) systolic function because of its ease of application. TAPSE using transesophageal echocardiography (TEE) is limited by alignment with the lateral wall of the RV. Modified TAPSE (m-TAPSE) is a novel method for measuring TAPSE....

Relationship between right ventricular systolic function, mean pulmonary arterial pressure and left ventricular ejection fraction in hypertensive heart failure patients seen at the obafemi awolowo university teaching hospitals complex, Ile-Ife Atendi AB, Ogunyemi SA, Adebayo RA, et al.. Relationship between right ventricular systolic function, mean pulmonary arterial pressure and left ventricular ejection fraction in hypertensive heart failure patients seen at the obafemi awolowo university teaching hospitals complex, Ile-Ife. Clin Cardiol J 2023;7(1):1-6. ABSTRACT Background: The role of the Right Ventricle (RV) has been largely underestimated compared to left ventricle in cardiac diseases. Nowadays the importance of RV has been recognized as independent risk factor for mortality in heart failure. Elevated mean Pulmonary Arterial Pressure (mPAP) is also a recognized independent predictor in heart failure patients. There is a scarcity of data evaluating this relationship in heart failure patients in sub-Sahara Africa. This study was therefore designed to establish the relationship between RV systolic function, Left ventricular ejection fraction and mPAP in hypertensive heart failure patients in Obafemi Awolowo university teaching hospitals complex. Methodology: Eighty patients with heart failure secondary to hypertension and 80 normal controls underwent clinical, electrocardiographic and echocardiographic evaluation. Indices of right ventricular systolic function that were measured include Tricuspid Annular Plane Systolic Excursion (TAPSE), and Right Ventricular Myocardial Performance Index (RVMPI) and mPAP was derived from RV outflow tract acceleration time after pulse interrogation at level of pulmonary valve. Results: forty two (52.5%) and 22 (27.5%) heart failure patients had right ventricular systolic dysfunction and right ventricular global dysfunction respectively as measured by TAPSE and RVMPI. Elevated mean pulmonary artery pressure was found in 38 (47.5%) of the hypertensive heart failure patients. There was no relationship between the indices of right ventricular systolic function and the estimated mean pulmonary artery pressures. There were also no significant relationships between left ventricular ejection fraction and estimated mPAP. The independent predictor of right ventricular systolic dysfunction was the LV ejection fraction. Conclusion: Right ventricular systolic function is impaired in patients with heart failure secondary to hypertensive heart disease. There is no relationship between the indices of right ventricular systolic function and mean pulmonary artery pressure. Further studies are needed to assess right ventricular systolic function in Nigerians.
... (104) ECG is a diagnostic imaging technique that provides measurements of both the functional and structural RV characteristics. These variables include the RV fractional area of change, RV Tei index tricuspid and annular plane systolic excursion (TAPSE) [12] . ECG seems to be the most suitable modality for longitudinal monitoring of postoperative patients with tetralogy of TOF, given its cost-effectiveness and widespread accessibility across various healthcare settings [13] . ...
... The early recognition of RVMI in a patient with acute MI is of prime importance, not only for prognostication purposes, but also because it can guide specific therapy, including aggressive primary PCI, with particular attention to RV branch revascularization, in order to limit the deleterious effects of this diagnosis [10]. Echocardiography is a non-invasive and available method for RV function assessment [11]. Because of the complex anatomy, non-invasive evaluation of the right ventricular functions may be challenging. ...
... 9 RV systolic functions can be assessed with parameters such as RIMP, TAPSE, 2D RV FAC, 2D RV ejection fraction (EF), threedimensional (3D) RV EF, tissue Dopplerderived tricuspid lateral annular systolic velocity, and longitudinal strain and strain rate. TAPSE is known to be well correlated with parameters of RV global systolic function, such as radionuclide-derived RV EF, 2D RV FAC, and 2D RV EF. 10 With the introduction of reperfusion therapy and aggressive efforts to modify risk factors, the prognosis of patients with ischemic heart disease has improved markedly. The rate of cardiovascular events after myocardial infarction has decreased to approximately 5% over a period of two years as compared with the 20% to 30% reported in the prethrombolytic era. ...
s: Right ventricular (RV) function provides strong prognostic information in patients treated with primary percutaneous coronary intervention (PCI) due to myocardial infarction. Longitudinal RV systolic function can be assessed by the measurement of the tricuspid annular plane systolic excursion (TAPSE). This study aimed to evaluate the correlation between TAPSE and revascularization time with 30-day mortality using TIMI risk score in patients presenting STEMI who underwent revascularization of right coronary artery (RCA). This was a descriptive amd analytical study. Data were collected from iSTEMI Registry database which consisted of 49 STEMI patients undergoing PCI in RCA and TAPSE measurement at Prof. Dr. R. D. Kandou General Hospital from October 3rd, 2018 to July 28th, 2019. Echocardiographic examination was done within 48 hours of hospitalization. A descriptive analysis and bivariate correlation with Spearman’s rho were applied between given variables. P-value of <0.05 was considered to be statistically significant. The results showed that the mean age of the patients was 57.92 10.345 years old and 79.2% were male. The mean TAPSE measurement was 18.51 mm +/- 3.63 mm. The median revascularization time was 357.5 minutes while median TIMI score was 4. Shorter treatment time (p=0.708) and lower TIMI score (p=0.923) were not associated with better right ventricular function measured with TAPSE in patients undergoing RCA intervention. In conclusion, right ventricular function is not associated with revascularization time and thirty days mortality in patients presenting with ST-elevation acute myocardial infarction involving right coronary artery.Keywords: tricuspid annular plane systolic excursion; revascularization time; right coronary artery; ST-elevation myocardial infarction
... 5 Dimensions of the right ventricle: RV basal measurement (in the basal one-third), mid cavity (at the LV papillary muscles' level), and longitudinal dimensions on a 4-chamber right ventricle-focused image must be performed in people with right-sided cardiac illness. 6 FAC in the right ventricle is computed by dividing (end-diastolic area-end-systolic area) by 100 and expressed as a percentage. FAC is produced in the apical 4 chamber view by tracing the endocardium of the right ventricular in systole and diastole. ...
Background: Chronic kidney disease (CKD) seems to be a serious issue which is becoming increasingly prevalent worldwide. The prevalence of hypertension, DM, and cardiovascular illnesses all contribute to an increase in the burden of CKD.
Aim of the Work: Utilizing 2D speckle tracking echocardiography as a noninvasive and quantitative method to evaluate the function of the RV in chronic hemodialysis patients.
Patients and Methods: This research compared 50 chronic hemodialysis patients (group I) referred to the Department of Cardiology at Sayed Galal University Hospital to 10 healthy individuals (group II) of matched age and gender. They were assessed for baseline characteristics, admission data, electrocardiography and echocardiographic parameters.
Results: Hemodialysis patients had significantly lower RV global longitudinal strain. The global RVLS (right ventricle longitudinal strain) has been shown to be significantly inversely related to age and RV diameters (longitudinal diameter and mid cavity diameter) and tricuspid E∕A ratio. While it showed significant positive correlation with FAC and LV ejection fraction. In group I patients, the tricuspid valve's E wave velocity and the tricuspid E/A ratio were both substantially lower. The tricuspid valve's A\ wave velocity was considerably higher in group I patients. A significant reduction has been found in the tricuspid valve E\ and S velocities in group I patients, whereas the A velocities of the tricuspid valve were significantly enhanced. In group I patients, MPI was significantly higher
... ICM patients have increased RVEDD and RVESD with reduction of RVEF% and TAPSE in comparison with the control group. Our results were concordant with an Egyptian study done by William and El Kilany [10] who assessed right ventricular function by echocardiography in 100 patients with chronic ...
Background: Ischemic cardiomyopathy [ICM] refers to the reduced pumping ability of the heart due to damage of myocardium as a result of ischemia. Thus, early detection of coronary artery disease could save the myocardium. Speckle tracking emerged as a new diagnostic tool, but its role in ischemic cardiomyopathy is not well addressed. Aim of the work: To assess right ventricle [RV] function by two-dimensional [2D] speckle tracking imaging in patients with ICM. Patients and Methods: This study included 38 patients with ICM and 30 healthy subjects as a control group. Conventional echo-Doppler parameters of right ventricular function together with tissue Doppler imaging derived RV strain and speckle-tracking echo-derived RV global strain [STE-RVGST] were addressed. Results: The two groups were matched in age and sex. ICM had significantly higher values of LV Tei index [0.90±0.28] versus control group [0.51±0.13] with p value
... MPI, which is an index of sensitive and load-independent cardiac dysfunction, shows subtle RV systolic and/or diastolic abnormalities. [21][22][23] Similarly, the diastolic and systolic indices of cTDI echocardiography revealed impairment of RV function in patients with ESLD. These findings suggest impaired diastolic and systolic RV function and increased RV filling pressure in liver transplant candidates with ESLD. ...
Objective:
There are various cardiovascular abnormalities in end-stage liver disease (ESLD). In these patients, left ventricular (LV) systolic function is normal at rest but deteriorates during stress. This deterioration may be due to subclinical myocardial dysfunction. This study evaluated global LV and right ventricular (RV) functions using 2-dimensional (2D) speckle tracking in patients with ESLD.
Methods:
Forty liver transplant candidates with ESLD and 26 healthy individuals were included in the study. All of the patients underwent conventional echocardiographic measurement. Longitudinal, circumferential, and radial strain measurements, as well as apical and parasternal short-axis image recordings were obtained. All 2D strain measurements were measured with offline analysis using velocity vector imaging (VVI) software.
Results:
In the apical 4- and 2-chamber measurements, the LV mean longitudinal strain was significantly lower in the patient group compared with that of the control group (-16.0±3.2% versus -17.6±2.2%, -16.7±3.3% versus -18.7 ±2.1 ± 2.1 %; p=0.002, respectively). The LV mean circumfe-rential strain did not differ between groups. The LV mean radial strain and RV longitudinal strain were significantly lower in the patient group (45.4±10.7 vs. 52.7±10.8%; p=0.01 and -19.2±3.5% versus -21.5±3.6%; p=0.03, respectively).
Conclusion:
Subclinical impairment of global LV and RV systolic functions was determined in liver transplantation candidates using VVI. This deterioration was detected in longitudinal and radial deformation rather than circumferential deformation mechanics, which is consistent with early-stage LV myocardial dysfunction.
... In patients with impaired cardiac output, forward failure from a decrease in arterial perfusion 25 as well as backward failure from right ventricular dysfunction 26 might contribute to renal dysfunction. In most patients with valvular heart disease, pulmonary hypertension is not readily resolved after surgery, 27,28 and chronic right ventricular pressure overload gradually leads to structural and functional deterioration of the right ventricle. 29 Accordingly, we found that the median values for RAP and RVSP in TTE (before surgery, at discharge, as well as 3 and 12 months after surgery) were significantly greater in patients with AKI than in patients without AKI (all P<.001) (Table E4). ...
Objective:
The association between acute kidney injury (AKI) and chronic kidney disease (CKD) remains elusive in cardiac surgery. We investigated the association between postoperative AKI and CKD development, emphasizing the intermediary role of acute kidney disease (AKD), in patients undergoing valvular heart surgery.
Methods:
We assessed the occurrence of postoperative AKI (7 days postsurgery), AKD (3 months postsurgery), and CKD (12 months postsurgery) in 1386 patients. The primary outcome was the development of AKD and CKD according to AKI occurrence. Relevant risk factors of AKI, AKD, and CKD were identified through multivariable regression analysis.
Results:
AKI occurred in 23.9% of patients with normal preoperative renal function. Even with early recovery of renal function within 3 days, AKI increased the risk of AKD (odds ratio [OR], 3.21; 95% confidence interval [CI], 1.98-5.20, P < .001) and CKD (OR, 2.86; 95% CI, 1.68-4.86, P < .001), whereas persistent AKI further increased the risk of AKD (OR, 12.07; 95% CI, 5.56-26.21, P < .001) and CKD (OR, 10.54; 95% CI, 4.01-27.76, P < .001). We also found these relationships in patients with pre-existing renal dysfunction. Multivariable analysis identified 3-month postoperative heart failure and high right ventricular systolic pressure as independent risk factors for CKD.
Conclusions:
Even after early recovery, postvalvular heart surgery AKI was associated with increased risk of CKD via AKD in a graded manner related to AKI severity and persistence. Postoperative cardiac dysfunction assessed 3 months postsurgery also significantly influenced CKD development, indicating a need for close follow-up of cardiac and renal function to improve patient outcomes.
... Although the essence of SEATAK, TAPSE & TASV-TDI is evaluation of longitudinal RV function, this study showed that the correlation of (12) who assessed of RVF by echocardiography in 100 patients with chronic left sided heart failure (LVEF <40%). In their study, RV systolic dysfunction (defined as presence of these three parameters together FAC <35%, TAPSE <16 mm and TASV-TDI < 10 cm/s) was found in 36% of patients& RIMP was significantly higher values in these patients. ...
Objectives
We aimed to investigate the association between right ventricular longitudinal strain measured by two-dimensional speckle-tracking echocardiography (2D-STE) and right heart catheterization data in pediatric patients with pulmonary hypertension (PH).
Methods
Two groups were evaluated, each consisting of 58 patients. Group 1, patients with PH; Group 2, normal matched controls. Data were collected from 58 patients with PH who underwent invasive hemodynamic evaluation. Standard transthoracic echocardiographic assessment was performed in all patients under the same circumstances. All patients underwent 2D-STE, and off-line analysis generated right ventricle longitudinal strain (RVLS) and right ventricular free wall strain (RVFW) and collected echocardiographic conventional parameters of right ventricular function, including the control group. The relationship between invasive characteristics and right ventricular function parameters was analyzed.
Results
In all, 58 PH patients were included in our study. The mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance (PVR) were strongly correlated with right ventricular free wall strain (RVFW) and right ventricular longitudinal strain (RVLS), moderately correlated with the right ventricle myocardial performance index (Tei index), weakly correlated with the transverse diameter of the right ventricle (RV) and the transverse diameter of the right atrium (RA), and moderately negatively correlated with right ventricular fractional area change (RVFAC). In terms of segments of the right ventricular free wall, the basal segment had the highest correlation coefficient with mPAP and PVR (r = 0.413, 0.523, 0.578, r = 0.421, 0.533, 0.575, p < 0.05, respectively). Tricuspid annular plane systolic excursion (TAPSE), main pulmonary artery diameter (MPA), peak systolic velocity of the right ventricle (RV-S’), and RA area parameters were not associated with mPAP and PVR (p > 0.05).
Conclusions
Right ventricular longitudinal strain is a reliable indicator to evaluate right ventricular function in pediatric patients with PH. It can provide valuable reference information for the clinical judgment of the status and severity of the disease in children.
