Catheter ablation for patients with anomalous pulmonary venous return and atrial fibrillation: a case report and literature review.

When performing catheter ablation for anomalous pulmonary venous return and atrial fibrillation, it is essential to consider ablating the irregular pulmonary vein before surgery. This helps to reduce surgical complications and the likelihood of atrial fibrillation recurrence. This case report highlights the challenges encountered during ablation in patients with atrial fibrillation and anomalous pulmonary venous return. In addition, we have reviewed the literature to offer insights into the development of ablation strategies for similar patients.
