Right heart failure, or right-sided heart failure, occurs when the right ventricle is unable to effectively pump blood to the lungs, leading to a range of symptoms and findings. One of the hallmark signs of right heart failure is fluid retention that can result in ascites – which is the accumulation of fluid in the abdominal cavity. This is due to increased venous pressure as fluid backs up in the venous system, leading to transudation of fluid into the peritoneal space.

Ascites can be observed in patients with conditions such as congestive heart failure where right ventricular dysfunction is present. Other clinical manifestations of right heart failure include peripheral edema, jugular venous distention (JVD), and hepatomegaly, all of which stem from increased pressures in the right atrium and systemic venous circulation.

In contrast, elevated pulmonary artery occlusion pressure primarily indicates left heart dysfunction and is more aligned with left heart failure rather than right heart failure. A shortened PR interval does not specifically correlate with right heart failure but may suggest an abnormal conduction pathway. A wide QRS complex is often associated with ventricular conduction abnormalities or left bundle branch block, which do not specifically indicate right heart failure. Thus, the presence of ascites is a strong
