MARQUEZ-GONZALEZ, Horacio et al. Definitions, mechanisms and prognostic factors of right ventricular dysfunction in congenital heart disease. Rev. Mex. Cardiol [online]. 2015, vol.26, n.4, pp.187-194. ISSN 0188-2198.

The right ventricle (RV) and its dysfunction have been directly associated to negative prognosis in patients with ischemic heart disease. In congenital heart disease (CHD), right ventricle dysfunction results from volume (diastolic) and pressure (systolic) overload mechanisms, considering the many embryonic alterations they hold. Currently, there are no operational definitions to classify right ventricle dysfunction (RVD) in patients with congenital heart disease; and both prognostic or recovery factors are different to those in patients with right coronary ischemic disease. In this paper, we review causes of RVD, etiologic mechanisms and related prognostic variables.
