[HSF] Indications for maze with mitral surgery

[erdinç naseri]

Prasanna,
Since there are no specialized intra-atrial conducting pathways ( at least to my knowledge) aren't all these cox- maze I,II;..X  injuring the myocardium arbitrary.In order for AF to persist there must be enough micro re-enterant circuits so that the AF wavelets can be sustainable. What we do is to stop the fibrilation wavelets from being indefinitely travelling! in atrial tissue.Logically the more the injury the less the chance of recurrence. But then of course you will have atrial electro-mechanical dissociation
