[HSF] Indications for maze with mitral surgery

[Prasanna Simha M]

I was confused with what you were referring to . The eMAZE set of
lesions were designed as a combination of lesions learnt from Cox's
works and from EP lesions done for flutter elimination. The IVC to TV
Isthmic lesion set was basically one used by electrophysiologists for
flutter ablation and I used this specifically as one of the aims of
Cox lesions was to eliminate the flutter cycle. I had no access to a
cryoprobe so I had to design a lesion that will work and yet not cause
a CHB. That is why I used an Isthmic lesion and the two alternate
lesions - one like COX Maze 2 over the appendage to the dome and the
one fro SVC to a point over the anteroseptal commissure.
I had to modify lesions based on Cox's lesion sets and the EP work
available at that time (started designing the lesion sets in ' 94- '
95 when I was trying to design appropriate lesions and doing
experiments with excised atrial appendages). I am not claiming that
these lesions exactly reduplicate the Cox Maze 3 but use the same
physiological basis to get similar blockage of the circus  movement if
I can call it that.
