Balloon Atrial Septostomy (BAS) is a minimally invasive cardiac procedure used to treat newborns with congenital heart defects (CHD) such as transposition of the great arteries (TGA). This procedure helps improve oxygenated blood circulation by enlarging an opening in the atrial septum, ensuring better survival until corrective surgery is performed.

Key Benefits of Balloon Atrial Septostomy

• Improves oxygen levels in the bloodstream

• Stabilizes critically ill newborns

• Prepares the patient for future corrective surgeries

• Minimally invasive with a short recovery time

How the Procedure is Performed

• A catheter with a balloon at its tip is inserted through a vein and guided into the heart.
• The balloon is inflated to widen the atrial septum, allowing better oxygenated blood flow.
• The balloon is then deflated and removed.
• The patient is monitored to ensure stable heart function before further treatment.

Risks and Complications

Although generally safe, Balloon Atrial Septostomy may involve some risks, including:

• Arrhythmia (irregular heartbeat)
• Blood clot formation
• Bleeding or infection
• Rare cases of heart perforation
