Biventricular repair in unbalanced atrioventricular septal defect.
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/m(2) 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.
