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 ...

An ostium primum atrial septal defect (ASD) occurs when then atrial septum near the atrioventricular valves has a communication between the two atrium causing a left to right shunt. This rarely ...

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 ...

† Primum (2 patients), secundum (68 patients) and sinus defects (4 patients). § Surgical branch of the study. TEE = Transesophageal echocardiography. *Children and adults. † Percutaneous branch of the ...

An atrial septal defect of the secundum type is relatively common and occurs from failure of the septum secundum to develop. This results in a communication between the left and right atrium directly ...

Atrioventricular septal defects (AVSD) comprise a spectrum of congenital heart malformations characterised by a deficiency of the atrioventricular septum, often resulting in a common atrioventricular ...

DEFECTS of the interauricular septum in the human being carry a variable prognosis. Small openings are known to be tolerated rather well through a long span of life. Large defects give left-to-right ...

This paper presents serial cardiac-catheterization data showing spontaneous functional closure of large symptomatic defects in 3 infants. One had an associated moderate-sized patent ductus arteriosus ...

Heart defect repair is surgery to fix a heart problem that prevents blood from flowing as it should through the heart. The doctor will make a large cut in your chest. The cut is called an incision. It ...

In children with perimembranous ventricular septal defects (VSDs), closure with a catheter-delivered occluder device is safe, providing midterm outcomes similar to those of open-heart surgery, ...

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 ...
