Sleep apnea does not predict atrial flutter recurrence after atrial flutter ablation

Abstract

Prevalence of SA in patients with AFL was 27%. SA was not found to be a predictor of AFL recurrence after successful AFL ablation.

A New Application for CPAP in Preventing Atrial Fibrillation

“…Furthermore, the patients were not randomized to treatment and control groups, reducing the overall impact of the results It should be noted that this study's results confl ict with a similar study by van Oosten et al 10 In that retrospective study of patients undergoing AF ablation, there was a much lower incidence of OSA compared with the present study (27% vs 82%). This was not a randomized evaluation of CPAP as a treatment strategy; initiation of CPAP was at the discretion of the treating physicians and occurred selectively in the most severe cases of OSA.…”

Obstructive Sleep Apnea in Patients With Typical Atrial Flutter

“…On the other hand, it is accepted by the authors that the retrospective nature of the analysis, in contrast to our prospective cohort, may result in an underestimation of the actual prevalence of OSA in patients with AF. 2 Overall, treatment with CPAP was not accompanied by a lower incidence of AFib during follow-up ( P 5 .24). However, CPAP was associated with a reduction in the incidence of "newly diagnosed" AFib in those 30 patients without AFib at inclusion, from six of 13 (46%) to one of 17 (6%) cases ( P 5 .025) ( Fig 1 ).…”

“…12 In contrast, the prevalence of OSA in patients with AF remains unknown, and it is unclear whether CPAP may reduce the incidence of AFib after CTI ablation. 2 This study was conducted to assess the prevalence of OSA in a cohort of patients with AF undergoing CTI ablation and to determine the impact of CPAP in reducing the incidence of AFib in the long term.…”

“…1 Nevertheless, about one-third of patients may develop atrial fi brillation (AFib) in the long term after CTI ablation, with this proportion increasing up to 52% when AFib is diagnosed prior to CTI ablation. 1,2 Obstructive sleep apnea (OSA) not only is a frequent underlying condition in patients with AFib ( Յ 24% of cases): Also, between 32% and 49% of patients with Background: The clinical yield of cavotricuspid isthmus (CTI) radiofrequency ablation of atrial fl utter (AF) is limited by a high incidence of atrial fi brillation (AFib) in the long term. Among other acknowledged variables, the association of obstructive sleep apnea (OSA) could favor incomplete arrhythmia control in this setting.…”

Sleep apnea, cardiac arrhythmias, and conduction disorders

“…We recently published our experience of patients with typical AFL undergoing radiofrequency ablation of the cavotricuspid isthmus. 27 The prevalence of OSA was 27% with an average AHI of 51.8 ± 34.9. However, OSA resulted not to be a predictor of AFL recurrence (6.1% in patients with SA vs 11.2% in patients without SA; P, not significant) after a successful ablation.…”
