Figure 2. Flowchart study population.
Overview of the included and excluded patients. This figure shows the
selection process of patients undergoing repeat AF ablations from eight
centers in the Netherlands (2016-2019; NHR). Out of 2311 patients, 1956
eligible patient were identified after excluding those with no AF (n=2)
and those with surgical ablation, prior ablation outside the PVs, or an
indication for atrial flutter/tachycardia (n=353). Among eligible
patients, 1617 had reconnected pulmonary veins (PVs), 65 had missing PV
reconnection data, and a total of 274 patients had all PVs isolated,
which were included in the final analyses.

specific ablation strategy; B) Pie chart showing the percentage
