Key result
Intravascular beta-radiation induced transmural necrosis of pulmonary vein myocardial sleeves without significant stenosis (luminal area reduced by 1.3%) in a swine model.
Why the study?
Does intravascular beta-radiation induce transmural necrosis of PV myocardial sleeves without causing PV stenosis in a swine model?
Does intravascular beta-radiation induce transmural necrosis of PV myocardial sleeves without causing PV stenosis in a swine model?
Intravascular beta-radiation effectively induces transmural necrosis and fibrosis of PV myocardial sleeves without causing significant PV stenosis in a swine model, indicating potential for AF ablation.

Hypothesis-generating for radiation-based PV isolation in AF; leaves open human translation and safety trials.
Pérez‐Castellano et al. (2006) studied Atrial fibrillation (swine model) (n=10). Intravascular beta-radiation was evaluated on Pathological effects including PV sleeve necrosis and PV stenosis. Intravascular beta-radiation induced transmural necrosis of pulmonary vein myocardial sleeves without significant stenosis (luminal area reduced by 1.3%) in a swine model.
