Have Medical Questions? Ask a Doctor Online!
Hello, this is Dr. David. I am reviewing your question now and will be with you momentarily.
Atrial fibrillation affects your heart’s ability to pump blood properly.
This can cause blood to pool in an area of the heart called the left atrial appendage . There, blood cells can stick together and form a clot.
In people with AFib not caused by heart valve problems, more than 90% of stroke-causing clots that come from the heart are formed in the left atrial appendage
The WATCHMAN Implant is designed to permanently block off the LAA and keep these blood clots from escaping.
the device can be removed if needed.
no antirejection drugs are needed after the procedure.
there are other options such as pace makers which can implanted to help control heart rhythms if you continue to have afib.
let me know if you have questions.
