To the Editor:
We read with great interest the article by Fender et al.1 Severe pulmonary vein (PV) stenosis is a major complication of catheter ablation, which can lead to significant morbidity and mortality. Its nonspecific symptoms and delayed onset from the time of ablation underscore the importance of a high index of suspicion for successful diagnosis and prompt management. The authors describe their approach to diagnosis using dedicated contrast computer tomography (CT) timed for optimal PV enhancement, noting a high concordance with ventilation-perfusion scan findings and superior spatial resolution compared with magnetic resonance imaging.2 However, given the inherent anatomic variability and lack of a standardized approach …
