【 摘 要 】

Pulmonary vein stenosis (PVS) post radiofrequency ablation for chronic atrial fibrillation poses a diagnostic challenge for the clinician. PVS presents with nonspecific symptoms, signs and radiographic features, and may be associated with significant pulmonary vascular involvement. Interestingly, others have described variation of the pulmonary artery wedge pressure between sites of the lung as a clue to pulmonary veno-occlusive disorders. We report, to the best of our knowledge, the first case that describes the regional loss of V waves while recording the mean pulmonary artery wedge pressure (mPawp) as well as the difference in pulmonary artery wedge pressure gradients as the main diagnostic clues for PVS.
