0340: Initial experience with ultra-high density electroanatomical mapping for arrhythmias - 12/02/16
Résumé |
Purpose |
We report our initial experience with the newly released ultra-high density (UHD) electroanatomical mapping system (Rhythmia, Boston Scientific) for arrhythmias.
Methods |
All procedures using the multielectrodes catheter (Orion, Boston Scientific) in our institution, for arrhythmias mapping were analyzed. Procedure and fluoroscopy times were also assessed.
Results |
20 patients were included (67,9±13 y) for radiofrequency ablation of accessory pathway (n=2) / typical flutter (n=5) / atrial fibrillation (AF n=2) / post-AF ablation left atrial tachycardia (AT n=6) / focal AT (n=2)/ left and right ventricular ectopies (n=3). 63 maps (3,15 maps per patient) were acquired within a mean mapping time of 18±10min per map, including a mean number of 10024,3±9371 electrograms per map (Figure): RA maps (flutter=12; sinus rhythm SR=14; coronary sinus CS pacing=4); left atrial maps (during tachycardia=18; SR=3; CS pacing=4); right ventricular maps (n=4); left ventricular maps (during tachycardia=3; pacing=1). Acute success was achieved in 19/20 patients. In one patient, the ablation could not be performed in the absence of clinical ectopies. Total procedure and fluoroscopy times were respectively 232±78min and 15,9±8min. No periprocedural complications were noticed.
Conclusion |
UHD electroanatomical endocardial mapping can be safely performed in both atria and ventricles and allows fast and accurate mapping.
