Left Atrial Appendage (LAA) Closure - An Overview
The Left Atrial Appendage is a small pouch, shaped like a windsock, found in the top left of your heart( the Left Atrium). Like your appendix, your Left Atrial Appendage doesn’t really have a clear role to play in your body.
In Atrial Fibrillation, the heart beats very rapidly, causing blood clots that can lead to strokes. In such life-threatening situations, Dr. Karthigesan may suggest the Left Atrial Appendage Closure or Left Atrial Appendage Occluder(LAAO) to minimise the risk of stroke.
This minimally invasive procedure closes the opening to the left atrial appendage to prevent blood clots that break off from here from swimming into your bloodstream. If you have suffered an A-Fib and are at an increased risk of a stroke, Dr. Karthigesan may put you on blood thinners as a precautionary measure. Unfortunately, however, if you are at risk of falling or bleeding out, he may recommend the LAA closure, which is a better option than blood thinners.
The primary objective of this procedure is to close your left atrial appendage, a small sac attached to the left atrium wall and reduce the risk of a stroke.
With his wide-ranging experience in Cardiology, Dr. Karthigesan has successfully treated innumerable patients with various cardiac complications. He is a one-of-a-kind doctor who believes in and practices compassionate, empathetic care coupled with the latest cardiac treatments. His expertise includes interventional cardiology, device therapy and various other life-saving treatments for your heart.

LAA Closure: More Details Explained
The LAA closure is a catheter-based keyhole procedure done under IV sedation or general anaesthesia. Dr. Karthigesan will start the procedure from the groin area. The closure device is taken into the left atrium and positioned in LAA under transesophageal or intracardiac ECHO and fluoroscopy guidance.
Although we are yet to find a guaranteed way for stroke prevention, LAA appendage closure significantly reduces your stroke risks because most strokes that begin from the atrium commence from the LAA. According to device studies, people with left atrial appendage closure devices also have a lower stroke risk.
