Abstract:
:The physiology and hemodynamic functions of the right ventricle in normal and disease states differ considerably from those of the left ventricle. To illuminate these differences, the right ventricle's essential functions in the normal circulation are reviewed, its functional anatomy and blood supply are described, principles and methods of systolic function assessment are discussed, and hemodynamic adaptations to selected diseases causing chronic right-side volume and pressure overload are highlighted.
