Why the study?
RV-PA uncoupling is associated with poor outcomes in VHD, prompting a summary of its prognostic significance.
What is the prognostic significance of right ventricular-pulmonary artery (RV-PA) coupling in patients with valvular heart disease?
What is the prognostic significance of right ventricular-pulmonary artery (RV-PA) coupling in patients with valvular heart disease?
This review highlights that RV-PA uncoupling is an important prognostic marker associated with poor outcomes in patients with valvular heart disease.
May refine risk stratification in valvular heart disease; leaves open whether targeted interventions improve outcomes.
Valvular heart disease (VHD) leading to inadequate hemodynamic circulation is a major cause of cardiovascular morbidity and mortality worldwide. Right ventricular-pulmonary artery (RV-PA) coupling integrates the ability of RV contractility to adapt to increased pulmonary arterial afterload. If the right ventricle cannot adapt to the elevated afterload by increasing its contractile function, RV-PA uncoupling occurs. RV-PA uncoupling has been shown to be associated with poor outcomes in VHD. This review summarizes the prognostic significance of RV-PA coupling in patients with VHD.
