Key result
Mobile cardiac outpatient telemetry after AF ablation showed that only 40% of symptom-triggered events were AF, and including asymptomatic recurrences reduced the 6-month success rate from 70% to 50%.
Why the study?
Does mobile cardiac outpatient telemetry accurately correlate symptoms with atrial fibrillation recurrences in patients undergoing catheter ablation?
Observational (n=19)
Does mobile cardiac outpatient telemetry accurately correlate symptoms with atrial fibrillation recurrences in patients undergoing catheter ablation?
Wireless monitoring reveals that many symptoms post-AF ablation are not due to AF, and asymptomatic AF recurrences are common, though patient compliance with intensive monitoring is a limitation.
No takes yet. Share an insight, caveat, or question.
Symptom-based success overestimates ablation outcomes; leaves open optimal monitoring protocols for trials and practice.
Vasamreddy et al. (2006) conducted an observational in highly symptomatic drug refractory atrial fibrillation (n=19). mobile cardiac outpatient telemetry (MCOT) system was evaluated on feasibility and results of monitoring patients prior to and following catheter ablation of AF and correlation of symptoms with AF. Mobile cardiac outpatient telemetry after AF ablation showed that only 40% of symptom-triggered events were AF, and including asymptomatic recurrences reduced the 6-month success rate from 70% to 50%.
