Novel therapeutic approaches to preserve the right ventricle.

The right ventricle (RV) is increasingly recognized for its role in heart disease. In fact, RV function is a strong predictor of outcome in patients with cardiovascular disease. Although the focus in heart failure has been on the left ventricle (LV), recently the spotlight has been shifting to include the RV. The RV and LV have different embryological origins and respond differently to stressors and to therapies. Newer therapies targeting the RV have been investigated in an attempt to improve right-ventricular adaptation to cardiovascular diseases. In this review, we summarize the differences between the RV and LV and focus on novel therapies that target the RV.
