Why the study?
Does linear epicardial cryoablation create effective lesions without vascular injury in a porcine model?
Population
5 adult Yorkshire swine
Design
Preclinical
Key result
Linear epicardial cryoablation created homogeneous ablative lesions with a maximum depth of ~1.0 cm, without large vessel LAD injury but with potential risk to small coronary vessels.

Does linear epicardial cryoablation create effective lesions without vascular injury in a porcine model?
Linear epicardial cryoablation creates homogeneous lesions up to 1.0 cm deep without large vessel injury, but may pose a risk to small coronary vessels.
Hayase et al. (2023) studied Ventricular arrhythmias (animal model) (n=5). Linear epicardial cryoablation was evaluated on Tissue and vascular effects (lesion depth and coronary artery injury). Linear epicardial cryoablation created homogeneous ablative lesions with a maximum depth of ~1.0 cm, without large vessel LAD injury but with potential risk to small coronary vessels.
