Right heart failure (RHF) is a clinical syndrome in which the right heart's structures—most notably the right ventricle [RV]—function abnormally, impairing the right heart's ability to perfuse.
Left-sided heart failure is the most common type. When the right ventricle struggles to efficiently pump blood to the lungs, right-sided heart failure results.
Pulmonary hypertension is the main factor in right heart failure. Other reasons include pericardial disease, hereditary cardiomyopathy, RV myocarditis, and ischaemia.
