Conclusions
The focal activations may
represent the specific characteristics and electrical features of the AF
driver, which may be different from conventional AF substrates, such as
CFAE or LVA. DFAs identified using the novel mapping algorithm may play
an important role in the AF process and framework of AF maintenance and
may be an attractive therapeutic target for AF drivers associated with
improved procedural outcomes.
