2021, Heart Lung and CirculationCitation Excerpt :In the context of HF, increased RV load is driven by increased pulmonary venous congestion (elevated PAWP) which is also mirrored by an increased PADP and decreased PAC. These haemodynamic perturbations are strongly associated with poor long-term prognosis in patients with HF and further highlight the important role that the RV plays in defining prognosis in HF [31–35]. In this analysis, we found that PAPP≤0.58 was associated with unfavourable haemodynamics (lower PA pulse pressure, stroke volume pressure and systemic blood pressure, elevated PADP, PAWP, and heart-rate) which may signal RV-PA uncoupling.

2018, Journal of Cardiothoracic and Vascular AnesthesiaCitation Excerpt :The normal response to increased CO is recruitment of the pulmonary vasculature, resulting in a reduction in pulmonary artery pressure. Although this system is very efficient, the right ventricle remains 2-to-3 times more sensitive to changes in afterload than the left ventricle,32 which results in a nearly linear inverse relationship between RV afterload and RV ejection fraction.33 Therefore, reducing RV afterload is critical in the management of RV dysfunction/failure and has been shown to rapidly improve hemodynamics.34,35
Acute Drainage of Pericardial Effusion May Precipitate Right Ventricular Failure
2015, Journal of Cardiothoracic and Vascular AnesthesiaCitation Excerpt :However, any attempt to improve RV function may be counterproductive in the absence of an intact pericardial sac. This has been demonstrated in an animal study in which pericardiotomy unmasked persistent RV dysfunction in the setting of an increased afterload.4,8 In addition, the RV dilatation was much more significant after reopening of a previously sutured pericardium in post-cardiac surgery tamponade patients with pulmonary hypertension.7
