Key result
Cryoballoon pulmonary vein isolation was performed successfully without residual shunts or AF recurrences during a 12-month follow-up in a patient with an ASD closure device.
Why the study?
Atrial fibrillation is often associated with atrial septal defects, but defect closure rarely provides complete arrhythmia control.
Case Report (n=1)
No
Cryoballoon pulmonary vein isolation can be performed successfully and safely without causing residual shunts in patients with prior atrial septal defect closure devices.

Atrial fibrillation (AF) is the most commonly treated arrhythmia in clinical practice and is often found in association with an atrial septal defect (ASD). However, ASD closure rarely confers complete arrhythmia control. A 23-year-old man presented to our center with frequent episodes of palpitations. AF was documented in 12-lead electrocardiography, and echocardiography showed a secundum-type ASD, 14 mm in size, with a significant left-to-right shunt. ASD closure was performed successfully with an ASD occluder device with no residual shunting. During follow-up, the patient experienced several episodes of AF. Thirteen months after the ASD closure, cryoballoon pulmonary vein isolation was done successfully with no complications. During a 12-month follow-up, he had no symptoms or AF recurrences, and echocardiography showed no residual shunting. This study showed that cryoballoon pulmonary vein isolation could be performed successfully without residual shunts in patients with ASD closure devices.

Mokhtari et al. (2021) conducted a case report in Atrial fibrillation and atrial septal defect (n=1). Cryoballoon pulmonary vein isolation was evaluated on AF recurrences and residual shunting. Cryoballoon pulmonary vein isolation was performed successfully without residual shunts or AF recurrences during a 12-month follow-up in a patient with an ASD closure device.
