Which ASD is suitable for device closure?

Trans-catheter device closure of ASD (TC-ASD) has well-established efficacy and safety. For most individual patients with suitable anatomy, TC-ASD is the preferred method for treating ASD.

Is patent ductus arteriosus an ASD?

Atrial septal defect (ASD) and patent ductus arteriosus (PDA) are both common congenital heart diseases, but the combination of these two common cardiac defects is extremely rare. 1–3 Transcatheter closure of these defects is widely accepted as an alternative to surgical closure.

Is PDA device closure safe?

Patent ductus arteriosus (PDA) is a common form of congenital heart disease and forms about 5-10% of congenital heart diseases. Surgical closure is safe and effective; however, certain patients may experience some morbidity.

When does the patent ductus arteriosus close?

After birth, the ductus arteriosus normally closes within two or three days. In premature infants, the opening often takes longer to close. If the connection remains open, it’s referred to as a patent ductus arteriosus. The abnormal opening causes too much blood to flow to the baby’s lungs and heart.

Why does ductus arteriosus close?

The increased arterial oxygen tension and decrease in blood flow through the ductus arteriosus causes the ductus to constrict and functionally close by 12 to 24 hours of age in healthy, full-term newborns, with permanent (anatomic) closure occurring within 2 to 3 weeks.

What is PDA device closure?

A transcatheter PDA closure is a minimally-invasive (non-surgical) procedure to close the ductus arteriosus. Specialized heart doctors called pediatric cardiac interventionists use a procedure called cardiac catheterization to place a small device in the vessel, which closes the PDA.

How long does PDA take to close?

After birth, the ductus arteriosus normally closes within two or three days. In premature infants, the opening often takes longer to close. If the connection remains open, it’s referred to as a patent ductus arteriosus.

Is there a device to close a patent ductus arteriosus?

A new device for transcatheter closure of heart defects was constructed and used to close a patent ductus arteriosus (PDA) in seven adult patients and an atrial septal defect (ASD) in six adult patients. The device consisted of two self-opening umbrellas and a piece of Ivalon.

Can a Dacron patch close a ductus arteriosus?

A new device for transcatheter closure of heart defects was constructed and used to close a patent ductus arteriosus (PDA) in seven adult patients and an atrial septal defect (ASD) in six adult patients. The device consisted of two self-opening umbrellas and a piece of Ivalon. A Dacron patch was sewn on the “male” umbrella for the ASD closure.

What is patent ductus arteriosus in extremely low-birth-weight infants?

Patent ductus arteriosus (PDA) in extremely low-birth-weight infants puts this vulnerable population at high risks of morbidity and mortality. Inclusion of a multidisciplinary team and newly available transcatheter PDA occlusion devices in the management of these infants can mitigate those risks and …

Can transcatheter PDA occlusion devices improve outcomes in extremely low-birth-weight infants?

Patent ductus arteriosus (PDA) in extremely low-birth-weight infants puts this vulnerable population at high risks of morbidity and mortality. Inclusion of a multidisciplinary team and newly available transcatheter PDA occlusion devices in the management of these infants can mitigate those risks and promote better long-term outcomes.
