Corre？？o biventricular em defeito do septo atrioventricular desbalanceado

we present the case of a 2.5 year-old child with unbalanced atrioventricular septal defect due to a small left ventricle (lv) (mitral annulus of 10mm and a 0.4 ratio in relation to the tricuspid annulus, lvdd: 17 mm, lv vd2: 15 ml/m2 and lv/rv long-axis ratio of 0.71); he had a favorable outcome after biventricular surgical repair. normal lv development was observed three months after the operation (mitral annulus of 22 mm, with a 0.84 ratio in relation to the tricuspid annulus, and lvdd of 30 mm). current parameters for utilization of the hypoplastic ventricle are discussed.
