Abstract Background Pulmonary wave reflection, an important loading component on RV, would help better describe right ventricular (RV) – arterial uncouplingin type II pulmonary hypertension (PH). Methods This study included 105patients with type II PH (age = 72±13 years old, ejection fraction = 47±21%). Pulmonary wave reflection was characterised by estimating pressure and velocity profiles from Doppler measurement and separating pressure waveform into forward (Pf) and backward pressure (Pb) waves based on the concept of wave intensity. The relationship of RV strain against Pb or pulmonary artery systolic pressure (PASP) was compared between patients with and without subsequent event of worsening heart failure, using discriminant analysis. Results Sample profiles of pressure waveforms illustrated Pb accounted for a significant proportion of total pressure (figure A). When RV strain was plotted against Pb, the distribution of both group were clearly separated, indicating significant uncoupling in patients with events, whereas when plotted against PASP, the both groups were overlapped (figure B and C). Conclusions Pulmonary wave reflection can better describe RV-arterial uncoupling in type II PH. Funding Acknowledgement Type of funding source: None

Characteristic Analysis

Background: Right ventricular-pulmonary artery coupling (RVPAC) is a predictor of outcome in pulmonary hypertension. However, the role of this parameter in dilated cardiomyopathy (DCM) remains to be established. The aim of this study was to assess the contribution of RVPAC to the occurrence of severe heart failure (HF) symptoms in patients with DCM using three-dimensional (3D) echocardiography. Methods: We prospectively screened 139 outpatients with DCM, 105 of whom were enrolled and underwent 3D echocardiographic assessment. RVPAC was estimated non-invasively as the 3D right ventricular stroke volume (SV) to end-systolic volume (ESV) ratio. Severe HF symptoms were defined by New York Heart Association (NYHA) class III or IV. We evaluated differences in RVPAC across NYHA classes and the ability of RVPAC to predict severe symptoms. Results: Mean left ventricular (LV) ejection fraction was 28±7%. Mean RVPAC was 0.77±0.30 and it was significantly more impaired with increasing symptom severity (p=0.001). RVPAC was the only independent correlate of severe HF symptoms, after adjusting for age, diuretic use, LV systolic function, LV diastolic function and pulmonary artery systolic pressure (OR 0.035 [95% CI, 0.004 – 0.312], p=0.003). By receiver-operating characteristic analysis, the RVPAC cut-off value for predicting severely symptomatic status was 0.54 (area under the curve=0.712, p<0.001). Conclusion: 3D echocardiographic SV/ESV ratio is an independent correlate of severe HF symptoms in patients with DCM. 3D RVPAC might prove to be a useful risk stratification tool for these patients, should it be further validated in larger studies.

Background: Heart failure(HF) related early readmission (<30days) and mortality is higher in elderly patients. Right ventricular (RV) dysfunction is associated with worse prognosis in patients with HF with reduced ejection fraction (HFrEF). We evaluated effect of RV function (as measured by TAPSE - Tricuspid annular plane systolic excursion) and Pulmonary artery systolic pressure (PASP) on early HF readmission and mortality in elderly HF patients. Methods: This is single center observational study of elderly (≥65 years )patients with HFrEF. Patients with principal discharge diagnosis of HFrEF are included (n = 278, age 77 ± 9 years, 38% female, LVEF 29% ± 9%). Demographic and echocardiographic data are collected. TAPSE (as a marker of RV systolic dysfunction) and PASP are measured as per ASE guidelines. Prediction models are performed. Results: Among 278 patients, 62 patients ( 22.3%) had HF related early readmission and 123 patients (44%) died at the end of 5 year. On univariate analysis, older age, Hypertension, Diabetes, higher PASP , RV systolic dysfunction (TAPSE <16mm) and BMI< 25 are predictors of early readmission and mortality (P value <0.05). On multivariate logistic regression analysis, early HF readmission was predicted by TAPSE <16 mm (OR=23.6; p < 0.001; CI 10.23-54.60) and PASP >50 mmHg ( OR = 34; p < 0.001; 95 CI 14.08-82.81); five year all cause mortality was predicted by TAPSE < 16mm (OR = 1.85; p 0.023; 95 CI 1.08-3.16) and PASP >50 mmHg (OR = 2.11; p 0.009; 95 CI 1.19-3.72). Conclusion: TAPSE <16 mm and PASP >50 mmHg are strong predictors of early readmission and five year all cause mortality in elderly HF patients. The assessment of RV function through TAPSE and PASP, helps to risk-stratify elderly patients with HFrEF.
