Despite the promising results of pulsed field ablation in achieving linear lesions beyond pulmonary vein isolation, the durability of those lesions and the acute reconnections should be further investigated.

Eliminating the vein of Marshall might still be necessary in selected cases to achieve posterior mitral isthmus bidirectional block.

High-resolution electroanatomical mapping to identify potential gaps in the linear lesions continues to be vital when using the pulsed field ablation technique.
