Modified sutureless repair using left atrial appendage flap for acquired left-sided pulmonary vein stenosis

Pulmonary vein stenosis is a well-known complication after radiofrequency catheter ablation of atrial fibrillation. Although surgical repair is indicated for younger patients and patients with multiple stenoses, the appropriate procedure for acquired pulmonary vein stenosis has not been established. In this study, we report the successful outcome of our modified sutureless technique using a left atrial appendage flap for left-sided pulmonary vein stenosis after radiofrequency catheter ablation.
