Ablation procedures for atrial fibrillation(AF)are being performed with increasing frequency.One of the most serious complications is the development of pulmonary vein stenosis(PVS),which occurs in 1％ to 3％ of current series.The preferred therapy for symptomatic PVS is pulmonary vein(PV)angioplasty or stenting,but this treatment modality is still uncertain in China.The aim of this study was the evaluation of the short-term success and safety after PV stenting of severe stenosis and assess the effectiveness at mid-term follow-up.
