Key result
Immunohistochemical analysis identifies stent-based ablation lesions in the SVC and pulmonary veins.
Why the study?
Atrial fibrillation is mainly caused by ectopic pulses from myocardial sleeve tissue, and ablation of this tissue is increasingly used but requires identification of ablation lesions.
Key points are not available for this paper at this time.

Histological mapping of myocardial sleeves in AF may refine ablation strategies; leaves open whether findings alter recurrence rates in prospective trials.
Introduction In men, atrial fibrillation (AF) is the most important cardiac arrhythmia with an increasing prevalence due to an ageing population [1,2]. Besides a medical treatment of AF, ablation of myocardial sleeve tissue is increasingly used [3]. AF is mainly caused by the elicitation of ectopic pulses from myocardial sleeve tissue
