Transseptal Stent Treatment of Anastomotic Stricture after Repair of Partial Anomalous Pulmonary Venous Return

Abstract

Purpose:

To report the endovascular treatment of a stenosis of the pulmonary venous anastomosis following surgical treatment for partial anomalous pulmonary venous return.

Case Report:

A 60-year-old man presented with recurrent pleural effusions after correction of a partial anomalous left pulmonary venous return. Magnetic resonance imaging demonstrated focal stenosis at the anastomosis of the anomalous pulmonary vein to the left atrial appendage. Using a transseptal approach, the pulmonary vein stenosis was accessed and successfully stented. The patient's symptoms improved, and follow-up imaging demonstrated a patent stent without residual pressure gradient.

Conclusions:

Endovascular repair of a stenosis at the anastomosis of an anomalous pulmonary vein is possible and should be considered as a treatment option for this lesion.
