Surgical Treatment of Total Anomalous Pulmonary Venous Drainage with Atrial Fibrillation in an Adult: A Case Report and Literature Review
Keywords:total anomalous pulmonary venous drainage; atrial fibrillation; radiofrequency ablation
Total anomalous pulmonary venous drainage (TAPVD) is caused by the absence of the congenital connection between the pulmonary vein and left atrium. This causes blood drainage into the right atrium, resulting in poor development of the left atrium and increasing the burden for the right atrium. It is accompanied by an atrial septal defect. TAPVD mostly is diagnosed during the fetal period and rarely is reported in adults. Atrial fibrillation (AF), a common arrhythmia, originates primarily from the joint of the pulmonary vein and left atrium, whereas AF originating from the right atrium has not been documented. Herein, we report the case of a 45-year-old male diagnosed with TAPVD accompanied by AF. After the correction of TAPVD and radiofrequency ablation (RFA) for AF performed under general anesthesia and cardiopulmonary bypass, the patient returned to normal sinus rhythm and showed no AF recurrence during two years of follow up.
