CT complex may diagnose symptomatic postablation PVS; leaves open prospective validation before routine use.

What are the pulmonary CT parenchymal and vascular features diagnostic of postablation pulmonary vein stenosis in symptomatic patients?
A specific complex of pulmonary parenchymal and vascular CT findings is diagnostic of postablation pulmonary vein stenosis, a condition that rarely resolves even after stenting.
Goitein et al. (2019) conducted an observational in Postablation pulmonary vein stenosis (n=486). Computed tomography (CT) was evaluated on CT parenchymal and vascular changes. A typical CT complex of parenchymal and vascular findings in the affected lobe is diagnostic of postablation pulmonary vein stenosis, with abnormal findings present only in PVS grades 2 to 4 (n=14).
