Key result

Anastomosing the distal portion of the left superior pulmonary vein directly to the left atrial appendage maintained improved pulmonary blood flow at 6 months postoperatively in a case report.

Key Points

To review catheter-based and surgical management strategies for severe pulmonary vein stenosis and occlusion following catheter ablation for atrial fibrillation.
Reviewed outcomes of catheter-based interventions, including balloon angioplasty, bare metal stenting (diameter: 7-10 mm), and drug-eluting stents (diameter: 3-5 mm).
Evaluated conventional surgical patch angioplasty alongside a novel surgical bypass anastomosing the distal left superior pulmonary vein directly to the left atrial appendage.
Catheter stenting yields lower restenosis rates than balloon angioplasty alone, but restenosis still occurs in approximately 22% of cases, primarily from intimal hyperplasia.
Surgical patch angioplasty has a restenosis rate of 39% over 5 years, whereas direct anastomosis of the left superior pulmonary vein to the left atrial appendage maintained blood flow improvement at 6 months without artificial patches or antithrombotic therapy.

Intervention / Comparator

Anastomosis of the distal left superior pulmonary vein directly to the left atrial appendage

Limitations

Limited to a single case report requiring further accumulation of cases to demonstrate efficacy.
The surgical technique is anatomically limited to the left superior pulmonary vein.
Follow-up imaging was only performed at a single postoperative time point.
Scintigraphy did not demonstrate complete restoration of blood flow.
Possibility of mild restenosis at the anastomotic site could not be ruled out due to lack of luminal evaluation on CT.
Follow-up examinations performed at only a single time point postoperatively
Scintigraphy did not demonstrate complete restoration of blood flow
Luminal evaluation was not demonstrated on the CT image
Single case report requires accumulation of additional cases

Implication

Anastomosing the distal portion of a stenotic pulmonary vein directly to the left atrial appendage is a promising novel surgical approach that avoids stenting and antithrombotic therapy, though long-term patency requires further study.
