Pulmonary hypertension (PH) is a progressive disease caused by structural and functional changes in the pulmonary vasculature resulting from diverse etiologies. PH ultimately leads to increased right ventricular (RV) afterload, RV hypertrophy, fibrosis, and right heart failure (RHF). Moreover, RV fibrosis initially serves as a protective mechanism against pressure overload-induced RV dilatation, but eventually progresses to excessive fibrosis, which impairs cardiac function. This review explores the relationship between RV fibrosis and RV function in PH patients, examines the clinical relevance of this relationship, evaluates techniques for quantifying RV fibrosis, and presents potential therapeutic strategies aimed at preserving right heart function in PH patients.
