Clinical Presentation and Therapy of Atrial Septal Defect

Area of Science:

• Cardiology
• Developmental Biology
• Pediatrics

Background:

• Atrial septal defects (ASDs) represent a significant portion of congenital heart defects, accounting for 6-10%.
• The incidence of ASDs is approximately 1 in 1500 live births.
• A notable female predominance exists, with a 2:1 female-to-male ratio.

Purpose of the Study:

• To outline the classification of Atrial Septal Defects (ASDs).
• To categorize ASDs based on their embryological origins.

Main Methods:

• Review of embryological development related to the atrial septum.
• Classification of Atrial Septal Defects based on developmental origins.

Main Results:

• Identification of five distinct types of Atrial Septal Defects.
• Correlation of ASD types with specific embryological developmental pathways.

Conclusions:

• The embryological origin provides a framework for classifying the five types of ASDs.
• Understanding the embryological basis is crucial for characterizing different ASDs.
