Current management and clinical outcomes for catheter ablation of atrioventricular nodal re-entrant tachycardia
Key result
Catheter ablation for AVNRT achieves ~96% long-term success, with modern tools not altering clinical outcomes.
- n=877
Why the study?
Does the use of contemporary practices (3D mapping, anaesthesia, irrigated catheters) improve long-term success or reduce complications in patients undergoing catheter ablation for AVNRT?

Implication
AVNRT ablation yields durable success with minimal pacemaker risk; leaves open whether modern mapping or catheters add benefit in randomized settings.

Structured PICO
Does the use of contemporary practices (3D mapping, anaesthesia, irrigated catheters) improve long-term success or reduce complications in patients undergoing catheter ablation for AVNRT?
P
Population
877 patients undergoing initial ablation of atrioventricular nodal re-entrant tachycardia (AVNRT) between 1 July 2005 and 30 June 2015
I
Intervention
Catheter ablation for AVNRT (including contemporary practices like 3D electroanatomical mapping, anaesthesia, and irrigated catheters)
O
Outcome
Long-term procedural success, AVNRT recurrence, and complicationshard clinical
Catheter ablation for AVNRT remains highly successful with low complication rates, and the escalating use of contemporary tools like 3D mapping and irrigated catheters does not appear to significantly improve these already excellent outcomes.
Limitations
- Lack of prospective evaluation
Cite This Study
Chrispin et al. (2017) conducted a cohort in Atrioventricular nodal re-entrant tachycardia (AVNRT) (n=877). Catheter ablation was evaluated on Long-term procedural success. Catheter ablation for AVNRT achieved a 95.5% long-term procedural success rate and a 0.4% rate of AV block requiring a pacemaker, with modern mapping and ablation tools not altering clinical outcomes.
