Medtronic's Reveal® XT Insertable Cardiac Monitor Helps Determine AF Burden in Symptomatic and Asymptomatic Patients Following RF Ablation (MDT)

Medtronic, Inc. MDT today announced findings from the DISCERN AF trial, which utilized Medtronic's Reveal^® XT insertable cardiac monitor to conduct long-term monitoring to assess the incidence of symptomatic versus asymptomatic atrial fibrillation episodes in patients before and after undergoing radiofrequency ablation as compared to the AF status reported prior to the procedure. The clinical trial showed an 86 percent reduction in total AF burden (total amount of time spent in atrial fibrillation) from 2.0±0.5 hours per day per patient pre-ablation to 0.3±0.2 hours per day per patient post- ablation (p=0.005), with 56 percent of the total burden being asymptomatic.
