Dilated Cardiomyopathy: An Infrequent Cause of Posthepatic Portal Hypertension

Dilated cardiomyopathy is an infrequently encountered cause of posthepatic portal hypertension. In this case study, a patient presented with dilated cardiomyopathy with features of portal hypertension. Dilated portal and splenic veins with bidirectional flow, multiple portosystemic, and pelvic collaterals were observed. Grossly dilated inferior vena cava and hepatic veins with prominent right atrial pulsatality variations were also observed. While cardiomyopathy is described in literature as one of the causes of posthepatic portal hypertension, it is seldom documented.
