New device

Hi. I was having INR checked when the nurse asked if I had heard about the new device which is implanted to control AF. Very recent trials. Having just had av node ablation (Oct) was angry with myself for having it done. If this is fact why oh why didn't EP tell me to wait awhile instead of urging me to have AV node ablation. Has anyone heard of this? Presuming nurse has correct facts. Sunigirl.

  • What is the device?

  • Hi Yatsura

    The anticoagulant sister must have mixed up her info as it's probably the Watchman she was talking about. There is a post describing it. Would have been wonderful if true.

    One day soon maybe.

  • Sorry never heard of anything like that. Lots of new devices but not to CONTROL AF Also do remember that blood ladies are not always nurses so may not actually know much other than how to take blood.

  • Did she tell you what it was called. If so I am sure someone on here can tell you if it could control AF. I have never heard of anything like that.

  • After reading replies on herebI think the sister at anticoagulant clinic must have meant the Watchman device but this lowers risk of clots.

  • You got that one right Bob, but there was one of these ladies in my life many many years ago and she was full of information about everyone else. Merry Christmas. James H.

  • ????????

  • Don't knock yourself about sunigirl - IF such a thing existed it would be shouted about everywhere and a few cardiologists and EP's would know about it.

    The person who said this sounds like many others who have made misleading comments to AF patients - many on this site, myself included. A nurse did my annual Apixaban blood test and complained that 'we don't know where we are with these NOAC's, as we don't know the INR'. Enough said.

  • Hi Finvola. If trained staff don't know it doesn't help our confidence. Best Wishes sunigirl

  • I do agree. That's why the AFA and this forum are so important. Without the knowledge and confidence I have gained here, I would have been worried by my nurse's comment.

  • There is some truth in what the nurse said. With the OAC's, it's more or less a "size fits all" approach, whereas with warfarin, the INR would indicate where we stand.

  • You could just as easily say that warfarin is 'one-size fits all'. Those on it all strive to remain in the same therapeutic range in order to remain protected. On apixaban, I know exactly where I stand. I'm protected all the time - without any striving involved!

  • I felt (and still feel) that the nurse's comment was inappropriate and thoughtless at best. What a medical professional didn't appear to know - or consider important - was the difference in operation between the drugs' actions and the effect her comment may have had on a less-aware patient.

  • Hi please, what's OAC's please? J.

  • You are missing the point here. NOACs do not work on the same part of the clotting process as warfarin and therefore do not need testing. They work --end of.

  • There are a few new bits of information on the internet referring to something called the Watchman. I wonder if this is it?

  • Here's the Watchman

    Quote: "The WATCHMAN Device is intended for percutaneous, transcatheter closure of the left atrial appendage (LAA). Patients with non-valvular atrial fibrillation who are at increased risk for stroke and systemic embolism, are suitable for warfarin and seek a non-pharmacologic alternative to warfarin may be eligible for a WATCHMAN Device. By closing off the LAA, the risk of stroke may be reduced and, over time, patients may be able to stop taking warfarin."


  • 'and, over time'sounds ambiguous to me to say the Watchman.

  • Hi Seasider18.

    Yes ! It sounds the most likely. Thanks for sharing that info.

  • It was featured on South East News on BBC 1. My ears picked up as it was 'my' two cardiologists doing it. There was a later article in the Daily Mail on another hospital doing it but the link I saved says broken.

  • Yes there is a new device in trials but why would you prefer an implant which just controls AF and leaves a major scar compared to an ablation which leaves no indication it has happened and eliminates AF

  • You hardly see your pacemaker scar as it quickly fades. My pacemaker though looks much more prominent than it did. Cardiology registrar said the other week that it is well seated but my GP agrees with me that it moves. Not sure if he was joking when he asked if I wanted it removed.

  • It would appear that many ablations need to be repeated and the procedure is not risk free - it will be interesting to see how effective this device performs.

  • Almost every ablation will require a follow-up eventually though I'm still on my first, but it's going to be lower risk than the new technique which requires getting the unit close to the heart and then leaving it there.

  • As I understand it the watchman does nothing re eliminating the AF. What it supposedly does do is to cause the appendage to close up and therefore significantly reduce the chances of clots which then could cause a stroke.

  • No the Watchman is something else entirely.

  • Don't get too confident about ablations. They are very often not permanent Fixes. The younger you are the more likely to be successful in the long term.

  • Hi Mike11

    I have had three ablations which unfortunately failed. I have a pacemaker which has only a thin white scar where it was inserted just below left collar bone. Best Wishes

  • That's very unfortunate on the failed ablations, but I agree it can happen. A standard pacemaker isn't what we are talking about here though - the new treatment involves putting a unit inside the heart.

  • Could it be the Implantable Loop Recorder? I had one fitted 5 months ago. It comes in 3 parts. The implant ,an activator for when you get any symptoms and a transmitter to send details to go or the EP. This is made by Medtronic. Well worth trying.

  • It could be and sounds excellent. Thanks Davee.

    Best wishes

  • Think it is this : good video

  • See the following article.

  • Hi dave205

    I haven't seen this website (uptodate) but just had a quick look and will take time out tomorrow to read. Thanks so much.


  • Hi Sunigirl

    This is my first time posting on this forum, but I have a life long history of AF.

    I don't know your age, or AF history, but AV node ablation is considered by most educated EP's as the last option for AF.

    I was on medication for AF for 29 years before I was cured of AF. I had the Maze procedure done April 10 1998 By dr. Dale Geiss and have been cured since.

    Dr. Geiss moved to Davenport Iowa, but still does the maze.

    I'm leaving my Email address here if you need more info.

  • Thank you Jackdrum I will email you. I do feel a lost cause now. But I do my best to be positive and keep smiling. Thanks


  • Hi dmac4646, the loop I mentioned earlier today isn't a defibrillator but works as a type of ECG reading my hr continuously but can be further recorded by using the activator. Then by using the the transmitter can send details to hospital. Sorry for the confusion but hope I've cleared that up.

  • no problem thanks for clarifying.
