“…6 We report a high acute success rate of PSVT ablations, with extremely high individual success rates of AVNRT (99.8%) and AVRT (97%) ablations comparable to previous cohorts. 1,[7][8][9][10][11]18,19 Lower AT ablation success rates of 68% were observed in bi-atrial ablations compared to 85% in left or right atrial ablations in the German registry, 20 while higher success rates of right compared to left atrial ablations (89.6% vs. 68.7%) were noted in the Spanish registry. 9 We found AT ablations to be successful in 95.5% of cases, similar to a smaller cohort of Taiwanese patients at 98%.…”

“…There are reports describing associations between AVNRT ablation and the greater need for pacemakers in the coming years compared to patients undergoing AVRT and AT ablation. [9][10][11][12]14,19 Whilst these late-pacemaker rates were generally low (<1%), they may occur up to 9-years post AVNRT ablation. [7][8][9][10][11][12][13][14][15][16][17][18] This trend was not observed in our study, with lower rates of pacemaker implantation indicated for late AVB in AVNRT and AVRT (0.1%) compared to previous cohorts ranging between 0.2% to 0.7%.…”

“…[4][5][6] High acute success rates of >90% and low pacemaker or complication rates of <2% makes ablation a favorable treatment strategy in atrioventricular nodal reentrant tachycardia (AVNRT) and atrioventricular re-entrant tachycardia (AVRT). [6][7][8][9][10][11][12][13][14][15][16][17][18] Catheter ablation, with or without a trial of medical therapy, is endorsed by contemporary guidelines as a class I recommendation. 4,5 In contrast, lower success rates of >70% to 80% and higher mortality were reported in AT ablation.…”

Background:The Singapore Cardiac Databank was designed to monitor the performance and outcomes of catheter ablation. We investigated the outcomes of paroxysmal supraventricular tachycardia (PSVT)-ablation in a prospective, nationwide, cohort study.Methods: Atrioventricular nodal re-entrant tachycardia (AVNRT), atrioventricular reentry tachycardia (AVRT), or atrial tachycardia (AT)-ablations in Singapore from 2010 to 2018 were studied. Outcomes include acute success, periprocedural-complications, postoperative pacing requirement, arrhythmic recurrence and 1-year all-cause mortality.Results: Among 2260 patients (mean age 45 ± 18 years, 50% female, 57% AVNRT, 37% AVRT, 6% AT), overall acute success rates of PSVT-ablation was 98.4% and increased in order of AT, AVRT, and AVNRT (p < .001). Periprocedural cardiac tamponade occurred in two AVRT patients. A total of 15 pacemakers (6 within first 30-days, 9 after 30days) were implanted (seven AV block, eight sinus node dysfunction [SND]), with the highest incidence of pacemaker implantation after AT-ablation (5% vs. 0.6% AVNRT vs. 0.1% AVRT, p < .001). Repeat ablations (0.9% AVNRT, 7% AVRT, 4% AT, p < .001) were performed in 78 (3.5%) patients and 13 (0.6%) patients died within a year of ablation. Among outcomes considered adjusting for age, sex, PSVT-type and proceduretime, AT was independently associated with 6-fold increased odds of total (adjusted odds ratio [AOR] 6.32, 95% confidence interval [CI] 1.95-20.53) and late (AOR 6.38, 95% CI 1.39-29.29) pacemaker implantation, while AVRT was associated with higher arrhythmic recurrence with repeat ablations (AOR 4.72, 95% CI 2.36-9.44) compared to AVNRT.Conclusions: Contemporary PSVT ablation is safe with high acute success rates. Longterm outcomes differed by nature of the PSVT.
