Long-Term Effects of Right Ventricular Pressure and Volume Overload: A Comparative Analysis in an Ovine Model
Background/Objectives: Pressure overload (PO) and volume overload (VO) represent important mechanisms underlying right ventricular (RV) failure; however, long-term comparative data regarding their distinct pathophysiological consequences remain limited. This study aimed to compare the long-term effects of PO versus VO in a large animal model. Methods: Juvenile sheep were randomly assigned to either a PO group (n = 7) or a VO group (n = 8). PO was induced by pulmonary artery banding, whereas VO was induced by pulmon …
