Atrioventricular septal defect is a developmental irregularity in which a hole connects two or more chambers in your child’s heart. This hole may connect the top two, the bottom two, or all four ...

The goal of this study was to identify the contribution of large copy-number variants to Down syndrome–associated atrioventricular septal defects, the risk for which in the trisomic population is ...

During repair of atrioventricular septal defect (AVSD), surgeons may leave an atrial level shunt when they have concerns about postoperative pulmonary hypertension, a hypoplastic right ventricle (RV), ...

An atrial septal defect is an opening or hole in the wall that sits between the heart’s two upper chambers. The heart’s upper chambers are called the right and left atria. Some people refer to atrial ...

High-degree atrioventricular (AV) block (Mobitz II or complete AV block) was an indication in 117 (65%) patients. Forty-four patients (38%) of the 117 patients had congenital complete AV block, 12 of ...

The largest genetic study of congenital heart defects in individuals with Down syndrome found a connection to rare, large genetic deletions affecting cilia, scientists report. The high risk for ...

Transcatheter interventions have transformed the management of ventricular septal defects (VSDs), offering a minimally invasive alternative to open surgical repair. These procedures involve ...

The most commonly seen defects at birth are congenital heart defects (CHD). These anomalies arise when there is a failure of the heart or its major blood vessels to form properly during embryonic ...

The septum of the heart is a wall of tissue that separates the left and right sides of the heart and enables blood to flow as it should. It consists of the atrial septum and the ventricular septum.

An atrioventricular septal defect (AVSD) is a condition in which there is a hole between the chambers of the left and right sides of the heart. Additionally, the valves between the chambers may not ...

An atrioventricular canal is a congenital heart defect that connects chambers of your child’s heart that shouldn’t be connected. Atrioventricular canals usually require surgical treatment. It usually ...
