Chinese expert consensus on surgical treatment of congenital heart disease (6): complete atrioventricular septal defect / 中国胸心血管外科临床杂志

ABSTRACT

@#The congenital heart disease Atrioventricular Septal Defect (AVSD) are characterized by the deficiency of atrioventricular septal tissue with common AV junction, and classified as partial, complete or transitional. Complete atrioventricular septal defect (CAVSD) has been traditionally classified into A, B, and C three subtypes by Rastelli. The onset of age and severity of clinical symptoms depend on pulmonary blood flow and pulmonary artery pressure. Echocardiography is diagnostic, and the definitive diagnosis of CAVSD is the indication for surgical repair, which includes closure of ventricular septal defect, repair and partition of AV valves, and closure of ostium primum atrial septal defect. Potential post-operative complications include AV valves regurgitation, left ventricular outflow tract obstruction, arrhythmia and others. Based on the unique healthcare system of China, this article will focus on the surgical indication, timing of surgery, surgical techniques and long-term prognosis of this bi-Ventricular repair approach for patients with two functional ventricles without touching upon patients with hypoplastic ventricles and provides a summary of the general consensus of the Chinese congenital cardiac surgery community for CAVSD.
