Right ventricular failure (RVF) is the most important prognostic factor for both morbidity and mortality in pulmonary arterial hypertension (PAH), but also occurs in numerous other common diseases and conditions, including left ventricle dysfunction. RVF remains understudied compared with left ventricular failure (LVF). However, right and left ventricles have many differences at the morphological level or the embryologic origin, and respond differently to pressure overload. Therefore, knowledge from the left ventricle cannot be extrapolated to the right ventricle. Few studies have focused on the right ventricle and have permitted to increase our knowledge on the right ventricular-specific mechanisms driving decompensation. Here we review basic principles such as mechanisms accounting for right ventricle hypertrophy, dysfunction, and transition toward failure, with a focus on epigenetics, inflammatory, and metabolic processes.

Collagen content, the ratio of collagen types I and III and elastin content were measured in 5-6- and 10-12-week-old rabbits with and without right-ventricular pressure overload. Significant and equivalent hypertrophy occurred in both age groups. A 2-day pressure overload caused a fall in collagen concentration below control levels in right-ventricular tissue from the older animals, but no change in the younger ones. A 2-week pressure overload in the older animals resulted in a rise in collagen concentration, a decreased ratio of type III to type I plus III [III/(I + III)] collagens, a fall in desmosine concentration and a fall in the desmosine/hydroxyproline ratio in the right ventricle. None of these changes occurred in the younger age group. We hypothesize that the changes in connective-tissue proteins after overload in the older group may contribute to previously observed changes in mechanical performance. The divergent connective-tissue responses in the two groups suggest the importance of age in determining outcome, as well as the possibility of separate regulatory mechanisms for contractile and for architectural elements of the heart.
