. The study initially found that using advanced image-guided technology to target additional diseased areas causing arrhythmias, beyond the usual treatment zones, did not yield superior results compared to simpler methods.
"This shows that the younger population with AFib should be treated very quickly and not wait to get ablation treatment," said Dr. Nassir Marrouche, director of the Tulane Heart and Vascular Institute and The Research Innovation for Arrhythmia Discoveries at Tulane University School of Medicine."The earlier we treat an arrhythmia in younger populations, the better they do. In general, people tend to wait until they get older to seek treatment.
For the other group, doctors used the MRI scans to create a detailed 3D map of all diseased areas along the left atrium of the heart. They performed conventional PVI treatment and then used the digital map to ablate diseased tissue more aggressively and precisely outside of conventional treatment areas.
