ABSTRACT
Right heart failure (RHF) is a complex syndrome and carries a worse prognosis. The studies are limited in identifying gender differences in clinical and imaging findings of RHF. Method: a retrospective review of patients presenting with RHF. Results: 966 patients were reviewed; women accounted for 570 (59%) of patients with RHF. The mean age was 57±16 years. The most common co-morbidity included diabetes 419 (43%), class II obesity 323 (33.5%), and atrial fibrillation 409 (42%). The heart failure with preserved ejection fraction (HFpEF) was the dominant phenotype 601 (62%). Women had more HFpEF 415 (72.8%), while men had more HF with reduced EF (HFrEF) 207 (52.5%). The mean left ventricle (LV) dimension was 5.2±0.8 cm, and the mean right ventricle (RV) dimensions were 4.2±0.8 cm. Men had more RV dilation than women with an RV end-diastolic dimension of 4.4±0.8 cm, while in women, 4.1±0.8 with a p-value <0.0001. The mean tricuspid annular plane systolic excursion (TAPSE) was 1.4±0.5 cm, and the RV lateral wall s’ was 9±3. Men had more RV dysfunction, with TAPSE being 1.3±0.6 cm, while in women, it was 1.5±0.5 cm with a p-value of 0.002. The s’ of the lateral wall in men was 8.4±3 cm/s, while in women, it was 9.7±3.5 cm/s with a p-value of 0.004. Severe tricuspid valve (TV) regurgitation was more common in women 238 (41.7%). The TV intervention was equal for both genders. Conclusion: Women tend to have more HFpEF and a higher grade of TV regurgitation than men. However, men had more RV dilatation and dysfunction. Prospective studies will add to the understanding of the survival outcomes for men and women with RHF.

Introduction
Right heart failure (RHF) carries a high burden of mortality and morbidity. The definition of RHF is “the clinical syndrome of signs and symptoms of heart failure (HF) due to the right ventricle (RV) dysfunction.” The RHF is frequently associated with left ventricle (LV) systolic dysfunction. Variable conditions lead to RHF, including pressure overload, volume overload, and myopathies. High afterload leads to RV dilatation to maintain stroke volume. This will increase the end-diastolic volume and cause RV failure. The RHF can be acute or chronic; acute RHF can develop with a sudden change in the afterload, such as pulmonary embolism, RV myocardial infarction, or an increase in the preload after left ventricle assist devices implantation. Chronic causes of RV failure can be classified into cardiomyopathies, left-sided HF, valvular heart disease, or pulmonary hypertension (PHTN). A meta-analysis of studies involving HF patients with LV systolic dysfunction showed that RHF was present in 47% of these patients, and it was associated with a higher rate of HF hospitalization. The RHF is considered a prognostic marker for adverse outcomes in patients with cardiac disease. The tricuspid valve (TV) regurgitation occurs 80–90% in RHF. The severity of TV regurgitation is correlated with worse survival.
The European Society’s guidelines for valvular disease recommend intervention in TV regurgitation for patients with moderate or severe TV regurgitation who are undergoing left-sided valve surgery. Intervention is recommended for isolated TV regurgitation in the absence of severe RV dysfunction. The intervention for isolated TV regurgitation is underutilized; studies reported 16% mortality in the late stage of RHF. Timely intervention requires a comprehensive evaluation of RV function in addition to the clinical assessment. Non-invasive imaging evaluations of RV function include transthoracic echocardiography (ECHO), cardiac computerized tomography, and cardiac magnetic resonance imaging. Invasive right heart catheterization is the gold standard for assessing right-side filling pressure and pulmonary vascular pressures. ECHO assessment of the Tricuspid annular plane systolic excursion (TAPSE) is recommended for RV function quantification. A TAPSE of <16 mm indicates RV dysfunction and has a strong prognostic implication.
The gender variation in RHF presentation and prognosis is underreported. Women have unique cardiovascular risk factors related to autoimmune inflammatory disease, hormonal cycle, and pregnancy-related adverse outcomes. Obesity and hypertension are prevalent in women with heart failure. Women have more heart failure with preserved ejection fraction (HFpEF) due to arterial stiffness, hormonal changes, and diastolic dysfunction. Women with HFpEF have more HF hospitalization and have more RV dilatation and dysfunction than men. Female gender is a risk factor for PHTN; however, men have worse survival due to reduced RV adaptation to increased afterload. The variability in risk, co-morbidity, and phenotype presentation of RHF between genders needs further understanding.
Objective:
Describe the difference in clinical syndrome and imaging findings of right ventricle failure in both women and men.
Method:
This is a single-center retrospective observational study of patients with RHF as the primary diagnosis at admission and/or who received a TV intervention from 2010 to 2023.
INCLUSION CRITERIA:
-
History of HF admission requiring intravenous diuresis.
-
Presenting with symptoms of right-sided failure: ascites and lower limb edema.
-
And/or echo features of RV dysfunction and TV regurgitation based on American Society of ECHO (ASE) criteria.
-
Had previous TV intervention.
EXCLUSION CRITERIA:
-
Congenital heart disease.
-
Patients with systemic right ventricle or single ventricle.
The Outcome:
The gender variation difference between cardiovascular risk factors, HF phenotypes, and cardiac interventions for patients presenting with right-side heart failure.
Data Collection:
The medical records of all individuals involved in our study will be reviewed to collect the following data:
-
Clinical data: patients’ age, gender, diabetes (DM), hypertension, obesity, coronary artery disease (CAD), heart failure (HF) phenotype; heart failure with reduced ejection fraction (HFrEF) or preserved ejection fraction (HFpEF), atrial fibrillation (AF) and chronic kidney disease (CKD).
-
Echocardiogram parameters: Left ventricle ejection fraction (LVEF), LV end-diastolic volume, LV end-systolic volume, and TAPSE are the most frequently used parameters for RVF quantification.
American Society of Echocardiography (ASE) criteria for RV assessment include: TAPSE of <16 mm indicates RV dysfunction, and tissue Doppler of the free lateral wall (s’) measures the tricuspid annular plane’s longitudinal velocity (base to apex) by tissue Doppler imaging. <0.095 m/s indicates RV dysfunction. Pulmonary hypertension (PHTN) by ECHO criteria is based on the European Society of Cardiology PHTN guidelines. -
Cardiac intervention: coronary bypass surgery, TV surgical or percutaneous repair or replacement, mitral valve (MV) repair or replacement.
Statistical Analysis:
The data analysis was performed using XLSTAT version 2021.2.2 Life-Science.
For quantitative variables, the baseline characteristics for all the patients were reported as median and interquartile range (IQR) or mean ± standard deviation (SD).
Categorical variables were presented as numbers and percentages (%) as appropriate.
The correlation analysis was performed using chi-square, Fisher exact test, and logistic regression as appropriate.
The level of significance is defined as a p-value < 0.05.

ECHOCARDIOGRAPHIC FINDINGS:
Left Ventricle Dysfunction:
Patients with clinical presentation of right-side heart failure had either HFrEF or HFpEF. Women predominantly had HFpEF 415 (72.8%), and HFrEF occurred for 153 (26.8%). In women, the mean LVEF was 50 ± 10% compared to men with LVEF 42 ± 14.7%, p-value < 0.0001. The mean LV end-diastolic dimension in men was 5.5 ± 0.8 cm, while in women, it was 5 ± 0.7 cm with a p-value < 0.0001. The ECHO findings are presented in Table 2.
Right Ventricle Dysfunction:
RV dilatation and dysfunction were evaluated based on the American Society of Echocardiography (ASE) guidelines. The quantitative evaluation of the RV was only available for 363 patients on retrospective review. The mean RV dimension in this cohort was 4.2 ± 0.8 cm. The RV dimension in women was 4.1 ± 0.8 cm, while in men, it was 4.4 ± 0.8 cm.
The RV function was assessed using TAPSE and s’ of the lateral wall. The mean TAPSE was 1.4 ± 0.5 cm, and the mean s’ was 9 ± 3 cm/s. For women, the TAPSE was 1.5 ± 0.5 cm and s’ of the lateral wall 9.7 ± 3.5 cm/s, while in men, the TAPSE was 1.3 ± 0.6 cm and s’ was 8.4 ± 3 cm/s. The ECHO findings are presented in Table 2.
Most patients had PHTN with pulmonary pressure > 45 mmHg 565 (60.8%), measured by a non-invasive method. There was no difference in PHTN between men and women.

Table 2: Gender variation in ECHO findings in patients with right-sided heart failure
The gender differences in LVEF and LV dimensions were significant in HFrEF. The HFpEF population also had dilated ventricles with preserved LVEF, likely due to concomitant mitral regurgitation. The RV dimension and function were not statistically significant either in HFrEF or HFpEF. However, there was an increase in RV dimension in men compared to women, 4.5 ± 0.9 vs 4.2 ± 0.8 with a p-value of 0.012 (Table 3).

Mitral and tricuspid dysfunction:
The cohort of patients with right-sided heart failure had variable degrees of tricuspid valve regurgitation. The majority had either moderate TV regurgitation 397 (41.5%) or severe TV regurgitation 354 (37%). The women had TV regurgitation at moderate 219 (38.4%) or severe 238 (41.7%). However, men had a lower rate of severe TV regurgitation 116 (29%), while moderate TV regurgitation was present in 178 (45%).
Mitral valve (MV) regurgitation was present in 355 (81.8%) patients. The majority had severe MV regurgitation (36.7%), while moderate MV regurgitation was present in 156 (16%) and moderately severe in 92 (9.5%). The MV regurgitation was present in 527 (92.6%) of all women in the cohort. Most women had severe MV regurgitation 208 (63.5%) and moderate 96.
(16.9%). However, men had a lower rate of severe MV regurgitation, 147 (37%), and moderate MV regurgitation was present in 60 (15%). These findings are presented in (Figure 1).

Cardiac Intervention:
The patients who had coronary artery bypass surgery were 218 (22.5%), and women accounted for 94 (43%) of all cases compared to men 124 (56.9%).
The MV intervention was predominantly surgical; MV replacement was done in 449 (46.5%), while surgical repair was performed in 237 (24.6%).
The TV replacement was done in 533 (55%), while surgical repair occurred in 203 (21%), and percutaneous edge-to-edge repair in 11 (1%).
Isolated TV intervention occurred only in 26 (2.7%), while other cases were combined with left-side valve intervention. There was no significant difference in the TV intervention in severe TR between men and women (Table 4).

Discussion:
Women with HF have a high burden of comorbidities. Previous studies reported high prevalence of DM 272 (48.5%), hypertension 267 (47.6%), and AF 74 (13%) in women with HF. This study is a retrospective review of 966 patients admitted with right-sided HF in a tertiary hospital.
This cohort had a high representation of women with right-side HF 570 (59%), and showed prevalence of DM 238 (41.7%) and a higher prevalence of AF 273 (47.9%). Atrial arrhythmias are common in RHF and TV regurgitation. It can impair RV filling and worsen the RHF, and it is a marker of advanced disease and it’s associated with worse outcomes.
poor prognosis. Obesity in women is associated with a fivefold increase in risk of HF compared to men. Class II obesity with a BMI of 30–39.9 was highly prevalent in this cohort for women 232 (40.7%).
Most patients had HFpEF 601 (62%), with a mean LVEF of 47 ± 13.6%. In multiple studies, the RVF in HFpEF was present in 33% to 50% of patients. The HFpEF was higher in women than in men: 415 (72.8%) vs. 186 (47%), respectively. A prospective multicentre study for HFpEF showed that men had more RV end-diastolic diameter and lower TAPSE than women. The HFpEF cohort had a mean RV dimension of 3.4 cm compared to women 3 with a p-value <0.001. This study has shown that RHF in HFpEF is associated with RV remodeling. The RV dilatation was more pronounced in men than in women, 4.5 ± 0.9 vs 4.2 ± 0.8, with a p-value <0.012. PHTN was equally present in both genders in this study.
The TV regurgitation was present at variable degrees in both genders. The women had predominantly severe TV regurgitation at 238 (41.7%), while in men, 116 (29%) had a p-value <0.0001. The TV intervention was common in this cohort, with 533 (55%) undergoing TV replacement and 203 (21%) having repair. Studies looking at TV disease and intervention showed a higher prevalence of TV in women, 67%. In a prospective study evaluating patients undergoing Transcutaneous Edge to Edge Repair, the cohort had a higher degree of RV end-diastolic dimension of 5.3 ± 0.07 cm with severe TV regurgitation in 29% and torrential TV regurgitation in 37%.
Limitation:
This study has limitations related to its retrospective design. Its use of advanced imaging modalities, such as cardiac MRI and RV strain, was limited. Finally, many patients did not have follow-up data, thus, no survival analysis could be performed.
Conclusion:
Patients presenting with RHF have a higher burden of co-morbidities. The risk of developing RHF in HFpEF is higher, especially in women. RHF is commonly associated with moderate to severe TR. This cohort has a high rate of TV surgery; however, the outcome data around HF and mortality are lacking.
