Can pulmonary vein stenosis secondary to catheter ablation for atrial fibrillation cause haemoptysis?
Haemoptysis can be a rare presentation of pulmonary vein stenosis secondary to catheter ablation for atrial fibrillation, highlighting the need for physician awareness to avoid misdiagnosis.
Pulmonary vein stenosis post-AF ablation may present with haemoptysis; case reports leave open its frequency and optimal evaluation.
BACKGROUND: Haemoptysis is a common clinical symptom with a complicated aetiology. Patients usually visit pulmonologists initially and are misdiagnosed due to physician ignorance regarding the rare causes of haemoptysis. METHODS: We report three cases of haemoptysis due to pulmonary vein stenosis accompanied by catheter ablation for atrial fibrillation and review the related literature. RESULTS: The three patients presented haemoptysis and they all had the history of catheter ablation. They received kinds of non-invasive and invasive diagnostic and therapeutic procedures. Finally they were confirmed to have pulmonary vein stenosis by either pulmonary angiography or thorax computed tomography three-dimensional reconstructions. CONCLUSIONS: Haemoptysis could be caused by pulmonary vein stenosis secondary to catheter ablation for atrial fibrillation. Doctors should be aware of this rare aetiology.

Zhang et al. (2016) conducted a case report in Haemoptysis and pulmonary vein stenosis (n=3). Catheter ablation for atrial fibrillation was evaluated. Pulmonary vein stenosis secondary to catheter ablation for atrial fibrillation was confirmed as the cause of haemoptysis in 3 patients using pulmonary angiography or CT reconstructions.
