Spatiotemporal mapping for detection of anatomic locations of drivers of atrial fibrillation in swine

Our findings indicate that pre-PVI drivers for AFib were identified both within and outside the PV regions. Post-PVI drivers were located in different parts of LA. We also noted a predominance of non-PV drivers to be from the appendage, septal wall, and posterior wall. These data highlight the need for further research on these regions and underscore the importance of non-PV sites in AFib maintenance.
