摘要

Background

Severe pulmonary vein obstruction (PVO) is a rare but potentially serious complication following catheter ablation. In recent years, sutureless repair of PVO has been reported, with early.

Methods

We performed sutureless repair on eight cases of symptomatic PVO and evaluated the mid-term surgical outcomes. All patients were diagnosed with right or left pulmonary vein obstruction using computed tomography, and complete loss of pulmonary blood flow in the affected area was confirmed by pulmonary perfusion scintigraphy.

Results

Following surgery, symptoms resolved in all cases. Pulmonary perfusion scintigraphy was performed in all cases, confirming a significant improvement in pulmonary blood flow at the lesion sites. The atrial space observed immediately after surgery tended to decrease over the 6 to 12 months postoperatively, with the left atrium showing signs of remodeling during this period.

Conclusions

Our sutureless repair technique has demonstrated favorable mid-term outcomes and may serve as a viable alternative to traditional surgical. methods.
