Sorin Eno device & Medtronic leads

Hi all..Just a quick question.

I have just had a new pacemaker fitted in the last couple of month . My new device is the Sorin Eno & my leads are Medtronic. My original device was a Medtronic and also the one before that..Had endocarditis on the last device which was only in 3yrs and subsequently was removed last April.

So now have this new device on the opposite side and just want to get some information and peoples thoughts on it..It was recommended by Doc for its smaller size and I am now just wondering have I swapped quality and battery longevity for size?..I am pacing at 98% on the  right Atrium..

Many thanks in advance.

I know nothing of Sorin Eno but size wouldn't be on my list of wants.  My guess is that you're going to have real trouble getting an MRI, should you need one at some point.

Hello SPEEDY :   I have a Medtronic PM and would be very happy to be fitted with a Sorin ENO as it seems, on paper,  to offer real advantages over the Medronic ::-

-  small size is only one of the claimed advantages

- the Sorin " Rate Response" feature is better at increasing your heart-rate when you exercise.The Medtronic just relies on a single sensor detecting upper body movement. The Sorin has dual sensors and responds to an increase in breathing as well  as the upper body movement

-  the Sorin PM has a unique  feature which detects and reports sleep apnea

- the Sorin claims to reduce unnecessary right ventricular pacing which can be dangerous

-  you should be OK having an  MRI  scan if you need one as your Sorin PM automatically switches to safe mode when it detects an MRI magnetic field. Your existing Medtronic leads are almost certainly MRI-compatible. I had  an MRI scan recently and needed the PM tech to be there to switch my Medtronic to safe mode. As the Sorin does that automatically , having an MRI scan should theoretically be easier.

When my current Medtronic PM needs replacing I am thinking of switching brands...maybe to a Sorin. You certainly haven't swapped quality just for size !

Best of luck with your new technically-advanced friend

The problem getting an MRI is finding someone to do it given that the PM and leads aren't from the same manufacturer. They haven't been tested together and neither company will stand behind the conglomeration. Radiologists are a risk-averse bunch and are unlikely to stick their neck out when neither manufacturer will back them up. It's hard enough to get an MRI when everything is from the same manufacturer, even when implanted at the same time. BTDT

I wonder if Drs are more risk-averse your side of the pond, Agent ?

I know that in the U.S. doctors are terrified of litigation and surveys in your country have shown that this fear affects their decision-making on patient care.

I see Speedy is in Europe ( Ireland ) where there is not the  same  " Let's sue the doctor  " culture which you all enjoy in America.   I would be amazed if he/she could not easily find a radiologist in Ireland willing to carry out an MRI on the Sorin / Medtronic combination. But who knows, I may be wrong.


Mixed manufacturers

Law suits probably have something to do with it but I can't imagine any doctor (being allowed to) try any random untested combination of intertwined technology. There is a difference between manufacturers, particularly where EMI is concerned, can be quite significant.

Thank you all for your comments, I'm more reassured now. My doctor has reassured me that I can get an MRI in same hospital should the need ever arise, at this stage I suppose all I can do is again put my trust in him..Thanks again guys

You know you're wired when...

You can finally prove that you have a heart.
