What causes enlargement of heart chambers

Question about heart

Slightly enlarged upper left heat chamber of heart after 4 Ablation procedures

Because it is over worked. In many cases it can return to normal if ablation stops AF.

AF is the culprit and stresses or overworks the pumping and chambers of the heart. Sorry to hear that you have had 4 ablations. After each ablation were you in normal sinus rhythm for awhile? When was your last one?

How are you feeling now and do you still have AF after your 4 ablations?

[lilyj54 in reply to jeanjeannie50]

No more Afib

After each ablation it improved a bit.

But not enough

Fourth ❤️😉

Hello

I have had 4 ablations as well and enlarged left chamber my ablations haven’t worked and now I am in persist AF

I do hope yours has worked as I have problems with 2 valves now

It is the AF

You should speak to your heart consultant about getting it under control

Good luck

A number of causes - endurance athletes often have much larger hearts but unless they detrain effectively this can lead to enlarged atria and subsequent AF; being in persistent fast AF for a long period; diseased or fibrous tissue in the atria; fatty tissue in the heart structure - ie: being overweight; drugs and alcohol - I’m sure there are a lot more causes but those are the ones I have heard of.

I gather that if the cause can be controlled or reversed then the atria will come back to normal size.
