Atrial septostomy is a medical procedure used to create a communication between the right and left atria of the heart. This procedure is primarily performed to alleviate symptoms in patients with certain congenital heart defects or severe pulmonary hypertension.

Indications

Atrial septostomy is indicated in patients with:

• Congenital heart defects such as transposition of the great arteries (TGA)
• Severe pulmonary hypertension
• Right heart failure due to increased pressure in the right atrium

Procedure

The procedure is typically performed using a balloon catheter inserted through a vein and guided to the heart. Once the catheter reaches the atrial septum, the balloon is inflated to create a hole, allowing blood to flow between the right and left atria. This can help to:

• Reduce pressure in the right atrium
• Improve oxygenation of blood
• Alleviate symptoms of heart failure

Complications

Potential complications of atrial septostomy include:

• Arrhythmias
• Pericardial effusion
• Infection
• Stroke

Post-procedure Care

After the procedure, patients are typically monitored in a cardiac care unit (CCU) for any immediate complications. Long-term follow-up includes regular echocardiography to assess the size of the atrial septal defect and the patient's clinical status.
