Key result
Pulmonary vein stenting relieves severe hemoptysis and reduces gradients in acquired pulmonary vein stenosis.
Why the study?
Acquired pulmonary vein stenosis is an infrequent complication of atrial fibrillation ablation that is often misdiagnosed due to predominant respiratory symptoms.

Acquired pulmonary vein stenosis is an increasingly recognized, potentially life-threatening complication of atrial fibrillation ablation that can be effectively treated with angioplasty and stenting.
May relieve severe symptoms in acquired pulmonary vein stenosis; leaves open durability and optimal management in larger cohorts.
BACKGROUND: Acquired pulmonary vein stenosis (PVS) is an infrequent complication of atrial fibrillation ablation that is often misdiagnosed due to predominant respiratory symptoms. It can result in pulmonary venous hypertension, with varying presentations, ranging from shortness of breath to haemoptysis. CASE SUMMARY: We report two patients with a history of paroxysmal atrial fibrillation treated with radiofrequency ablation and pulmonary vein (PV) isolation, who subsequently developed PVS. Case 1 initially presented with indolent symptoms of shortness of breath and cough. He was initially diagnosed with and treated for pneumonia. In contrast, Case 2 presented with massive haemoptysis, requiring intubation and intensive care unit admission. Both patients were eventually diagnosed with PVS by computed tomography. They were treated with PV angioplasty and stenting. DISCUSSION: While previously limited to the congenital heart disease population, PVS is occurring more frequently now in adult patients as a complication of ablation procedures. It is most effectively treated with angioplasty and stent implantation but has a high rate of recurrence.

Talmor et al. (2021) conducted a case report in Acquired pulmonary vein stenosis (n=2). Balloon angioplasty and pulmonary vein stenting was evaluated on Clinical and hemodynamic response to pulmonary vein stenting. Pulmonary vein balloon angioplasty and stenting successfully reduced pressure gradients and relieved severe haemoptysis and respiratory symptoms in two patients with acquired pulmonary vein stenosis.
