Anatomical and Physiological Patterns of Right Ventricle

Anatomy of right ventricle (RV) and some of its function was first described by Harvay W [1]. Since then, for many years until recent decades only a few researchers have tried to specify its prognostic importance in main cardiac diseases as right heart has been traditionally considered to have a little or at most secondary to left ventricle (LV) role in overall cardiac function and development of heart failure (HF) [2,3]. Researchers underestimated RV physiological importance in the maintenance of normal overall hemodynamic performance and described this chamber as just a passive conduit with a little pumping capability which just connects right atrium (RA) with pulmonary artery [4]. Such approaches were mainly due the fact that the evaluation of RV function was technically difficult (difficulty in accurately measuring RV volume as a result of its complex geometry etc.).
