tricuspid valve dysfunction

I strongly suggeset everyone on this forum with a 2 lead pacemaker at least scan an online article on tricuspid valve dysfunction. You will be surprised to learn about the number and seriousness of issues around the interference of PM leads with the triscuspid valve assembly. Based on my experience, some of the issues raised in earlier posts are likely derived from valve problems caused by PM leads.

The first order symptom of a damaged TV is regurgitation, which any doctor should pick up with a stethoscope. An echo would show damage in detail. As the article indicates, there are multiple ways a lead can interfere with a TV, including causing endocarditis, a very dangerous blood disease (I know). If you have symptoms that might derive from lead interference, get an echo and a blood test.

Thank you .... very interesting.    One of the first things I asked my cardiologist post-implant was " What are the downsides of shoving wires through my tricuspid valve,  will the valve still close OK ???

He was  slightly dismissive and then I had an ECHO .... surprise, surprise it showed slight leakage around the valve i.e. tricuspid regurgitation !  He was still fairly dismissive and said that it wasn't "clinically significant ".  I wonder !!

I wonder if slight fall offs in the ability to exercise could sometimes be due to the wires in the tricuspid valve causing valve malfunction and not necessarily due to chronotropic incompetence with the inevitable follow-up of various rate response  adjustments ??

I think it is a topic which EPs are not that happy about discussing.

Ian, This same thought occurred to me. SInce my PM installation 2 months ago, I have had 7 visits to program the rate-adaptive sensor and still don't feel like I am much ahead of where I was before the PM when I was dealing with bradycardia (I am an active athlete). SInce my recent echo shows "severe" TR, I now wonder whether the loss in cardio efficiency from the TR is offsetting any benefit I might be deriving from the PM. None of the techs have ever mentioned this, but I will be discussing with my cardio this week.


BTW---Do not take TR lightly! If this is happening because of damage as opposed to interference, you could be in serious trouble. I went through this with my mitral valve.

Is your severe TR a result of the PM leads?  What are they planning to do about it - replace the valve?  I am trying to decide if I should proceed with a CRT-D and this is just another thing for me to worry about :-(

Will learn more this coming week. Will update you. I had my mitral valve repaired 8 years ago and know that repair is preferable to replacement. If TR can be fixed by removing lead, then that is another approach to consider. On my first PM installation, EP tried to attach the ventricle lead to the bundle of His (inside the atrium). It failed and he then attached it inside the ventricle. He never fully explained why he tried the first apporach, but after reading about lead/valve interference, I think I know why.

You know you're wired when...

You have the perfect reason to show off your chest.
