Overview

Published with the inputs from Dr Balakumar K, Consultant, Cardiology,  Baby Memorial Hospitals- Thodupuzha

Transcatheter closure of septal defects is a minimally invasive, non-surgical heart procedure used to close small holes in the heart wall (called septal defects). These holes can occur between the upper chambers (Atrial Septal Defect - ASD) or lower chambers (Ventricular Septal Defect - VSD) of the heart.

Instead of open-heart surgery, this procedure uses a thin catheter inserted through a blood vessel to deliver a closure device that seals the defect. It is highly effective, safe, and offers a faster recovery compared to traditional surgery.

What is transcatheter closure of septal defects?

It is a non-surgical procedure performed by an interventional cardiologist to close a hole in the heart (ASD or VSD). A special umbrella-like device is guided through a catheter (usually from the groin) into the heart, where it seals the defect permanently.

When is transcatheter closure needed?

This procedure is recommended for:

  • Atrial Septal Defect (ASD) — when the hole causes right heart enlargement or excessive blood flow to the lungs
  • Ventricular Septal Defect (VSD) — in select cases when the defect does not close naturally and causes symptoms
  • Patent Foramen Ovale (PFO) — sometimes closed in patients with unexplained stroke or embolism

Your cardiologist will determine the need for closure based on the defect size, symptoms, and heart function.

How is transcatheter closure performed?
  • The procedure is done under local or general anesthesia in a cardiac catheterization lab.
  • A catheter (thin tube) is inserted through a vein in the groin and guided to the heart.
  • A closure device is deployed across the septal defect, sealing the hole.
  • Once positioned correctly, the device remains permanently, and the heart tissue gradually grows over it.
  • The procedure usually takes 1–2 hours, and most patients are discharged within 24 hours.
Is transcatheter closure safe?

Yes. It is a safe and well-established procedure with a high success rate (>95%). Complications are rare but may include minor bleeding at the puncture site or temporary irregular heart rhythms, which resolve quickly.

What is recovery like after transcatheter closure?
  • Hospital stay: Usually 1 day
  • Return to normal activities: Within 3–5 days
  • Medications: Blood thinners (like aspirin) may be prescribed for a few months
  • Follow-up: Echocardiography and clinical review are done to confirm closure success
What are the benefits of transcatheter closure?
  • No open-heart surgery or large scars
  • Short hospital stay and quick recovery
  • Less pain and fewer complications
  • Excellent long-term outcomes
  • Suitable for both children and adults with eligible heart defects
What is the difference between ASD and VSD closure?
  • ASD closure: Commonly performed through catheter-based procedures
  • VSD closure: Often depends on location and size — may be done surgically or via catheter in selected cases

Your cardiologist will evaluate the best approach for your specific condition.
