[Double-chambered right ventricle: case series]

The double-chambered right ventricle is a rare congenital heart disease caused by hypertrophic anomalous muscle bands that divide the ventricular cavity, resulting in the formation of a high-pressure proximal chamber and other low-pressure distal one. Because of its evolving nature, its diagnosis is usually made during adolescence or adulthood. While pediatricians see patients whose age range is well established, currently pediatric cardiologists attend patients with cardiopathies from the fetal stage to adulthood, because they are more familiar with these malformations. We report a series of cases treated with divided right ventricle in a new public hospital (Congenital heart disease Section) of Buenos Aires province.
