The Right Ventricle in Health and Disease: Insights into Physiology, Pathophysiology and Diagnostic Management

Until recently, the right ventricle (RV) received little attention in adult patients with congenital heart disease and even less attention in the setting of acquired heart failure. However, in the last two decades, our perspective towards the right side of the heart has begun to change. Advances in imaging modalities have permitted the accurate study of RV physiology and made it apparent that RV function is an important determinant of prognosis in heart failure irrespective of the underlying etiology. This article summarizes the existing data on the unique anatomical and physiological features of the RV. The hemodynamic conditions and cellular and biochemical pathways that lead to right heart failure are presented. Moreover, the imaging modalities that aid in the assessment of RV structure and function are described and the importance of the diagnostic and prognostic information they provide is discussed.
