Pulmonary vein (PV) stenosis (PVS) is a known complication of PV isolation procedures for AF (atrial fibrillation). PV angioplasty and stenting have been used as an effective therapy for PVS, yet high rates of restenosis are common. Experience with intravascular ultrasound (IVUS) in evaluating the PVS morphological characteristics and appropriate stent deployment is very limited. Furthermore, the use of IVUS could minimise the risk of restenosis. We describe the case of a patient with sub-occlusion of the left superior PV and total occlusion of the left inferior PV following catheter ablation for AF treated by stenting with IVUS guidance.
