Recent advances in managing septal defects: atrial septal defects

Area of Science:

• Cardiology
• Pediatric Cardiology
• Interventional Cardiology

Background:

• Atrial septal defects (ASDs) are congenital heart conditions characterized by abnormal openings between the atria.
• Four main types exist: ostium secundum, ostium primum, sinus venosus, and coronary sinus defects.
• Right ventricular volume overload is a primary indication for ASD closure.

Purpose of the Study:

• To review the management of atrial septal defects (ASDs).
• To highlight recent advancements in ASD treatment strategies.
• To differentiate management approaches based on ASD type.

Main Methods:

• Review of current literature on ASD management.
• Description of surgical and percutaneous closure techniques.
• Discussion of FDA-approved devices for transcatheter closure.

Main Results:

• Transcatheter closure is effective and preferred for ostium secundum ASDs.
• Percutaneous closure offers benefits like shorter hospital stays and faster recovery.
• Other ASD types typically necessitate surgical intervention.

Conclusions:

• Both surgical and percutaneous methods are safe and effective for ASD management.
• Timely closure of ASDs prevents further cardiac complications.
• Ostium secundum defects are well-suited for minimally invasive percutaneous closure.
