Characteristics of early recurrences detected by continuous cardiac monitoring influencing the long ‐term outcome after atrial fibrillation ablation

AbstractAimsEarly recurrences (ER) of atrial arrhythmias are common after catheter ablation of atrial fibrillation (AF). The significance of these ER is controversial.Based on data of continuous cardiac monitoring, we sought to investigate the characteristics of ER and their impact on late recurrences (LR) during follow ‐up.Methods126 patients with paroxysmal (49%) or persistent (51%) AF underwent an AF ablation with subsequent implantation of implantable loop recorder. Follow up was 12 months using remote monitoring. All atrial arrhythmia (AF or atrial tachycardia ‐AT‐) episodes>30sec. within the 3 ‐month blanking period were considered and the AF burden evaluated every 3 months.ResultsWithin the 3 ‐months blanking period 72 patients (57%) experienced an AF/AT recurrence. Survival free from any arrhythmia recurrence during follow‐up was 40% in patients with ER vs. 69% in those without ER. AF burden during blanking period and timing of ER correlated significantly with LR at 12 months (area under curve 0.74, p

ConclusionThe overall estimated incidence of AF and recurrent AF during pregnancy is as high as 2.2% and 39.2%, respectively. AF during pregnancy may result in poor maternal and fetal outcomes.

Cavo tricuspid isthmus ablation (CTIA) is considered an effective first-line treatment for typical atrial flutter (AFL). However, many patients develop atrial fibrillation (AF) after successful CTIA. Knowledge about recurrent arrhythmia after CTIA mainly comes from small cohort studies with limited follow-up.

Cardiorespiratory fitness predicts AF recurrence – CARDIO-FIT Study Obesity is an important risk factor for atrial fibrillation (AF) and lack of physical activity is an important risk factor for the development obesity. Weight loss has been shown to reduce the burden of AF [5]. Long-Term Effect of Goal-Directed Weight Management in an Atrial Fibrillation Cohort: A Long-Term Follow-Up Study (LEGACY) showed that progressive weight loss had a quantitative relationship with the reduction AF burden [2].

Readmissions post-TAVR is common, contributing to increased healthcare utilization and costs. Many factors have been discovered as predictors of readmission, however, sex-specific disparities in readmission ratesis limited.MethodsBetween January 2012 and September 2015, adult patients...

DiscussionRemote monitoring may improve clinical outcome if it uncovers conditions with low symptom burden which cause or indicate an increased risk. A simple and easily implementable response to the information is important. Cardiac arrhythmias frequently start as asymptomatic, shorter lasting, and nightly events. The BIO-GUARD-MI trial represents the first attempt to simplify the response to the rather complex nature of heart arrhythmias.Trial registrationClinical Trials,NCT02341534.

This study evaluated the impact of daily ECG self ‐recordings on time to documented recurrent atrial fibrillation (AF) or atrial flutter (AFL) and time to treatment of recurrent arrhythmia in patients undergoing catheter radiofrequency ablation (RFA) or direct current cardioversion (DCCV) for AF/AFL.BackgroundAF recurrence rates after RFA and DCCV are 20 ‐45% and 60‐80% respectively. Randomized trials comparing mobile ECG devices to standard of care have not been performed in an AF/AFL population after treatment.MethodsOf 262 patients consented, 238 were randomized to either standard of care (123) or to receive the i...
