Dr Thomas Arentz (Germany) went over the issue of brain lesions after AF ablation. He mostly talked about PVAC, which as we know was associated with an excess of brain lesions. In the end, the significance of non-symptomatic brain lesions is unknown. Interestingly, he pointed out that other well accepted heart procedures, like coronary angiograms, are associated with brain lesions as well. He also showed a beautiful MRI image of a non-contracting left atrium in a patient who had multiple extensive left atrial ablations, which highlights the idea that aggressive ablation strategies have downsides.

As an AF ablationist, I am conflicted about surgical ablation. That said, however, though the upfront risks are greater with surgery, the success rates are encouraging. Worries about surgical ablation beyond the immediate risks include how well the atrium will contract. Remember, regular electrical rhythm is good, but you also want the atria to transport blood to the ventricle. Medical people call this the mechanical function of the atria.

The second limitation stems from the fact that the researchers could not tease out the specific technique used to ablate AF. They knew a patient had AF ablation, but they could not tell whether (or what) additional ablation was done. Additional ablation beyond the standard PVI lesion set may be an important risk factor for complications and paradoxically, some believe, may actually lower the success rate. The best way to do AF ablation remains both unknown and hotly debated among leaders in the field. Questions like, when should right atrial flutter lines be made, should the SVC be isolated, should one look for extra-pulmonary triggers with adrenaline infusions, or in more advanced cases of AF, should additional lines be made, all remain unresolved.
