Cardiorenal syndrome (CRS) is a complex disease that results from the close relationship between cardiac and renal physiology. We present two cases which illustrate how renal vein congestion (case 1) and reduced cardiac output (case 2) can both lead to CRS type 1. We focused on the hemodynamic differences between these two cases, as we believe that a deep understanding of the pathophysiology and the renal blood flow (RBF) and renal perfusion pressure (RPP) in these two cases is key in the correct management strategy. This report highlights that CRS type 1 must be recognized as an acute process comprised of two distinct mechanisms, due to renal vein congestion or due to low cardiac output, which can present independently or in varying degrees in the same patient. In consequence, the role of renal vein congestion needs to be recognized early in order to adequately tailor patient treatment.
