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 ...

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 ...

† 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 ...

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 ...

An atrial septal defect is the persistence of a hole (the foramen ovale) in the wall (septum) between the right atrium and left atrium of the heart. The foramen ovale usually closes spontaneously ...

Using cardiac imaging during heart surgery can detect serious residual holes in the heart that may occur when surgeons repair a child's heart defect, and offers surgeons the opportunity to close those ...

Beijing Zhongke Journal Publising Co. Ltd. Congenital heart defects (CHDs) are the most common birth defects, occurring in approximately 0.9% of live births. Sadly, they are also the leading cause of ...

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 ...

After bicuspid aortic valve, ventricular septal defects (VSDs) are the most common congenital heart abnormalities. Of all congenital defects, around 20% are solitary lesions and another 10% are ...

Expert Rev Cardiovasc Ther. 2007;5(6):1135-1146. Diagnosing a secundum ASD is more often than not incidental because the defect normally causes symptoms late in adult life. Echocardiography and MRI ...
