Implication

Pulmonary vein stenosis warrants clinical vigilance after AF ablation; leaves open optimal diagnostic and therapeutic strategies.

Key Points

To summarize the mechanisms, reported incidence, diagnostic modalities, and therapeutic strategies associated with pulmonary vein stenosis following catheter ablation for atrial fibrillation.
Reviewed clinical findings on radiofrequency catheter ablation procedures targeting the pulmonary veins and left atrial tissue.
Assessed diagnostic utility of anatomic and functional modalities including computed tomography, magnetic resonance imaging, transesophageal echocardiography, and lung scanning.
Examined interventional management options, specifically balloon dilatation and stenting, along with modified ablation techniques.
Radiofrequency energy delivery inside or near pulmonary vein orifices causes luminal narrowing, though true incidence remains unknown due to nonuniform screening.
Clinical presentations vary widely and are frequently misdiagnosed, leading to significant delays in intervention and severe clinical consequences.
Treatment with pulmonary vein balloon dilatation or stenting carries high rates of recurrent narrowing, leaving long-term clinical prognosis unclear.

Outcome

This review highlights pulmonary vein stenosis as a severe complication of AF ablation, emphasizing the need for multimodality imaging for diagnosis and noting high restenosis rates with current treatments.

Limitations

The exact incidence is currently unknown because the diagnosis is dependent on the imaging modality and on the rigor with which patients are followed up.
The optimal method for screening patients has not been determined.
There is much uncertainty with respect to causative factors, incidence, diagnosis, and treatment, and long-term sequelae are unclear.
