@d050526 Sure! I’m glad to help in any way I can! If you bring up Boston Scientific on Google, or a search engine, type in ‘The Watchman’, and they have a video, that explains how the device is implanted in the heart. There is a right side appendage in the top right side of the heart, that when blood gets in, can possibly form blood clots. ‘The Watchman’ uses a coated titanium balloon type device to block the appendage off. Doctor’s secure the balloon in place, going through a vein, opened in the groin area, inserted with tubing. Think of how stents are placed to open up arteries, as to how this procedure is performed. A few weeks after the procedure a transesophageal imaging procedure is performed, on the patient, where the implant is checked, to make sure that skin is growing over the device, at the entrance to the appendage, where the balloon has been implanted, and to check and make sure that there is no leakage or possibility of blood clots forming. I have had ‘The Watchman’ implant installed by the cardiac team at the hospital, and last week, the transesophageal check was done! I have been on Eliquis blood thinner for the last three months, and this week the Docs put me on Plavix for another 6 months, along with a baby aspirin, a day! I didn’t have any discomfort or problems, with either procedure. Each one, of course, was done under anesthesia. My a-fib seems to be relatively controlled, with my watch recording that I have an average of 2% a-fib time, over a week’s time period! So, I’m doing fairly good, and have peace of mind that ‘The Watchman’ is working as it is designed to do! Hope this helps you, with your decision making!
