Key result
Cryoablation of atrial fibrillation prior to atrial septal defect closure improved right ventricular function and prevented AF episodes at one year in a 61-year-old female.
Why the study?
Does cryoballoon pulmonary vein isolation prior to percutaneous ASD closure improve right ventricular function and prevent AF episodes in a patient with ASD and paroxysmal AF?

Does cryoballoon pulmonary vein isolation prior to percutaneous ASD closure improve right ventricular function and prevent AF episodes in a patient with ASD and paroxysmal AF?
Cryoballoon pulmonary vein isolation prior to percutaneous ASD closure may be an effective strategy to manage concurrent paroxysmal AF and ASD.
May support combined cryoablation before ASD closure in paroxysmal AF; hypothesis-generating and leaves open efficacy in larger cohorts.
We report the case of a 61-year-old female who was admitted to our department with progressive dyspnea and palpitation. Transthoracic echocardiography and transesophageal echocardiography showed a small atrial septal defect (ASD, 8x7 mm). Paroxysmal atrial fibrillation (AF) was detected in Holter monitoring. As repair of ASD does not significantly reduce the risk of arrhythmias, cryoablation of AF was performed prior to ASD closure. On cardiac examination at one year, this combined intervention improved right ventricular function and prevented AF episodes.

Kudret Aytemir (2013) conducted a case report in Atrial septal defect and paroxysmal atrial fibrillation (n=1). Cryoablation of atrial fibrillation prior to atrial septal defect closure was evaluated on Right ventricular function and AF episodes. Cryoablation of atrial fibrillation prior to atrial septal defect closure improved right ventricular function and prevented AF episodes at one year in a 61-year-old female.
