ASD VSD Closure Catheterisation
Atrial Septal Defect (ASD) and Ventricular Septal Defect (VSD) closure through catheterization, commonly referred to as catheter-based intervention, is a minimally invasive procedure used to repair certain congenital heart defects. ASD and VSD are conditions where there are openings in the septum, the wall that separates the heart’s chambers, allowing abnormal blood flow between them. This procedure is an alternative to traditional open-heart surgery and offers several benefits:
- In ASD closure, a catheter is guided through a blood vessel, usually in the groin, to reach the heart.
- A device, typically an atrial septal occluder, is delivered through the catheter to the site of the defect.
- The device is then released, effectively sealing the hole in the atrial septum and preventing abnormal blood flow between the heart’s two upper chambers.
- This minimally invasive approach reduces the need for open-heart surgery and its associated risks, resulting in shorter hospital stays and quicker recovery times.
- In VSD closure, a similar catheter-based approach is used to reach the heart through a blood vessel.
- A device, known as a ventricular septal occluder, is positioned over the ventricular septal defect.
- The device is released, sealing the hole in the ventricular septum and preventing the abnormal shunting of blood between the heart’s two lower chambers.
- Just like with ASD closure, this method is less invasive than traditional surgical procedures, leading to shorter recovery times and reduced postoperative discomfort.
Both ASD and VSD closure through catheterization have proven effective in treating these congenital heart defects. They reduce the need for large surgical incisions and heart-lung bypass, which are associated with higher risks and longer recovery periods. This minimally invasive technique allows patients to return to their normal activities more quickly, making it a preferred option for many individuals with ASD or VSD. However, the suitability of this approach depends on the size and location of the defect, and the decision is made after thorough evaluation by a cardiac specialist.
