Key result
Older age was an independent risk factor for arrhythmia recurrence in patients over 40 with single ventricle physiology (HR 0.58; 95% CI 0.43-0.78; P<0.0001).
Why the study?
Arrhythmias are a well-known complication in patients with single ventricle physiology, but data regarding arrhythmias in older patients remain lacking.
Observational (n=29)
Hazard Ratio: 0.58 (95% CI 0.43–0.78)
p-value: p=< 0.0001
In older patients (>40 years) with single ventricle physiology, intra-atrial reentrant tachycardia and atrial fibrillation are common, and while acute treatment success is high, recurrence is frequent and associated with older age.
No takes yet. Share an insight, caveat, or question.
Frequent post-treatment recurrence in older single-ventricle patients warrants caution; leaves open optimal long-term strategies.
Pujol et al. (2022) conducted an observational in Arrhythmias in single ventricle physiology (n=29). Age was evaluated on Arrhythmia recurrence (HR 0.58, 95% CI 0.43-0.78, p=< 0.0001). Older age was an independent risk factor for arrhythmia recurrence in patients over 40 with single ventricle physiology (HR 0.58; 95% CI 0.43-0.78; P<0.0001).
