Abstract 16672: ICD Lead Performance in Athletes: Results of a Prospective Multinational Registry
Background: Concern has arisen that athletic activity increases risk of lead failure in those with an implanted defibrillator (ICD). A prospective international registry has followed athletes with ICDs. The current study is a post-hoc analysis of this registry focusing on lead failures.
Methods: Athletes with ICDs (age 10-60 years) participating in organized (N=328) or high-risk (N=44) sports were followed. Running, basketball, and soccer were the most common sports. Clinical outcomes including lead failures (changes in sensing or pacing) were adjudicated by two electrophysiologists.
Results: Median age was 33 years; 33% were female. Over a median 31-month follow-up, there were 27 lead failures. Predictors of lead failure were younger age (odd ratio: 3.1 (1.1 - 8.3) p=0.03), and Fidelis lead (odds ratio 4.8 (2.1 - 11.1) p < 0.001) The only independent predictor was Fidelis Lead. Type of structural heart disease, gender, participation in contact sports, sports with intense arm activity (e.g. swimming), or weight lifting did not predict lead failure.
Conclusions: Failure rates for the Fidelis were higher than has been reported for unselected populations. However, intense arm activity and contact sports did not predict failure in this cohort. Longer follow-up will be useful to develop more robust predictors of lead failure in athletes.
