An IVC diameter greater than 20 mm is commonly regarded as an upper limit of normal, which is a noninvasive indication of increased RA pressure in patients with cardiac or renal disease [4]. Portal hypertension (PH) is defined by a pathological increase in the pressure of the portal venous system, 1 with liver cirrhosis as the most common cause. Passive hepatic congestion, also known as congested liver in cardiac disease, describes the stasis of blood in the hepatic parenchyma, due to impaired hepatic venousdrainage, which leads to the dilation of central hepatic veins and hepatomegaly.
