An ASD device closure is a therapeutic procedure designed to address an Atrial Septal Defect (ASD) - an unusually large hole present between the upper chambers of the heart that persists after birth. If left untreated, this condition can result in heart enlargement, abnormal heart rhythms, and potential damage to the lung's blood vessels.
The ASD (Atrial Septal Defect) device closure procedure utilizes a specialized device to effectively seal the hole. It employs a patch to cover it or utilizes sutures to close it. There are several techniques available for ASD closure. While some cases may necessitate open-heart surgery, others can be addressed through a minimally invasive method known as cardiac catheterisation. In this approach, a catheter is threaded from a vein in your groin up to your heart.

While all babies are born with a small hole that typically closes within a few weeks or months, some babies may have a larger opening that does not seal naturally.
If the hole is too small( called PFO), it may not cause any symptom during daily activity but occasional shunting of blood across the hole might cause brain stroke. Hence it is recommended to close the PFO with device in Cryptogenic stroke. The ASD can lead to blood leakage into inappropriate chambers of the heart. Over time, this condition forces the heart and lungs to work harder, potentially triggering a series of health complications and symptoms such as:
ASD closure devices are not only used to prevent the above complications but also to avert strokes in individuals with a small ASD or patent foramen ovale (PFO). Similar to an ASD, a PFO allows blood to move in the wrong direction within the heart which can lead to stroke.
To fully understand your heart's condition and provide a detailed view of the ASD for an effective closure procedure, Dr Karthigesan may suggest you to undergo a series of diagnostic tests, including:
Yes, though the risk of complications associated with a transcatheter ASD closure is comparatively lower than with surgical ASD closure procedures. Although rare, potential complications can include bleeding, arrhythmia, infection around the closure device or keyhole site, kidney failure, or stroke or transient ischemic attack (TIA).
