Right ventricular dysfunction in Chagas' Cardiomyopathy. Primary involvement or a resonant manifestation of Left ventricular dysfunction?

Background Chagas’ Cardiomyopathy (CC) is an important cause of heart failure and sudden cardiac death (SCD) in Latin America. Migratory movements have spread carriers throughout the world, especially in USA and Europe. Left Ventricle (LV) involvement is a landmark and apical aneurysm a pathognomical sign. Nevertheless, early involvement of the right ventricle (RV) and RV systolic dysfunction in presence of normal left ventricular systolic function in CC has been a subject of controversy in the literature. Therefore, we analyzed a cohort of patients with CC in order to explore the presence of RV dysfunction.
