Unbalanced atrioventricular septal defect: definition and decision making.

Echocardiographic definition and surgical decision-making in unbalanced atrioventricular septal defect: a Congenital Heart Surgeons' Society multiinstitutional study.

BACKGROUND Although identification of unbalanced atrioventricular septal defect (AVSD) is obvious when extreme, exact criteria to define the limits of unbalanced are not available. We sought to validate an atrioventricular valve index (AVVI) (left atrioventricular valve area/total atrioventricular valve area, centimeters squared) as a discriminator of balanced and unbalanced forms of complete A...

Down Syndrome with Unbalanced Complete Atrioventricular Septal Defect and Truncus Arteriosus

Truncus arteriosus (TA) is a rare cardiac anomaly constituting less than 1% of all congenital heart defects. The association of complete atrioventricular septal defect (AVSD) and truncus arteriosus is uncommon. The management of this uncommon combination of lesions has not been well characterized and there is limited surgical options for treatment of these patients. We present our case report o...

Interrupted aortic arch and aortopulmonary window associated with complete atrioventricular septal defect.

We report a rare case of a neonate with interrupted aortic arch, aortopulmonary window and complete atrioventricular septal defect. To the best of our knowledge, this unusual triad has not been previously described. The main question of the surgical strategy for CAVSD, in setting of associated defects, is to classify the CAVSD as balanced or unbalanced.

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 ope...
