Biventricular repair in unbalanced atrioventricular septal defect.

Unbalanced atrioventricular septal defect: definition and decision making.

Unbalanced atrioventricular septal defect is an uncommon lesion with widely varying anatomic manifestations. When unbalance is severe, diagnosis and treatment is straightforward, directed toward single-ventricle palliation. Milder forms, however, pose a challenge to current diagnostic and therapeutic approaches. The transition from anatomies that are capable of sustaining biventricular physiolo...

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...

Current Surgical Outcomes of Congenital Heart Surgery for Patients With Down Syndrome in Japan.

BACKGROUND Current surgical outcomes of congenital heart surgery for patients with Down syndrome are unclear.Methods and Results:Of 29,087 operations between 2008 and 2012 registered in the Japan Congenital Cardiovascular Surgery Database (JCCVSD), 2,651 were carried out for patients with Down syndrome (9%). Of those, 5 major biventricular repair procedures [ventricular septal defect repair (n=...

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...
