Implication

Should not yet alter mapping strategy in focal atrial tachycardia ablation; leaves open need for randomized confirmation.

Structured PICO

Does CARTO electroanatomical mapping improve acute and 6-month success rates in patients undergoing catheter ablation for focal atrial tachycardia compared to conventional mapping?

Population

54 consecutive patients (60 procedures) undergoing catheter ablation of incessant or paroxysmal focal atrial tachycardia (FAT), mean age 54 ± 17 years, 39 females.

Intervention

Catheter ablation guided by CARTO electroanatomical mapping system (30 procedures).

Comparator

Catheter ablation guided by conventional mapping methods only (30 procedures).

Outcome

Acute success (absence and non-inducibility of FAT) and 6-month success (no recurrence of FAT episodes without antiarrhythmic drug therapy).hard clinical

CARTO electroanatomical mapping significantly improves acute and 6-month success rates of catheter ablation for focal atrial tachycardia compared to conventional mapping.

Limitations

Retrospective analysis
Non-randomized design
Success rate of conventionally mapped procedures was lower than reported previously
