Abstract:
Objective To investigate the efficiency and safety of stent implantation for severe pulmonary vein stenosis after radiofrequency ablation (RFA)of atrial fibrillation.Methods The clinical date of 231 cases with atrial fibrillation received RFA treatment were analyzed retrospectively.Eight cases were confirmed with severe pulmonary vein stenosis after RFA by CTA.The stents were implanted after angiography.Results All the 1 9 serious pulmonary vein stenosis from the 8 patients were treated stent implantation.The degree of pulmonary vein stenosis,trans-stenotic gradient,mean pulmonary pressure and the level of BNP were significantly decreased after treatment (P <0.01).The minimal diameter of the stenosis was significantly increased compared with preoperative (P <0.01).Six months after stenting,2 patients in 4 pulmonary veins were stenosis.The stenosis was successfully di-lated by repeated interventions with balloon dilation.There was no stenosis appeared in the patients after the repeated interventions with balloon dilation for 3 months.Conclusion Stenting implantation was a feasible and safety method for severe pulmonary vein stenosis after RFA.
