Percutaneous radiofrequency catheter ablation for atrial fibrillation prior to atrial septal defect closure.

abstract：BACKGROUND:Transseptal puncture (TP) is a prerequisite for LA ablations. LA access can be gained by catheter probing in case of PFO (trans-PFO method) or puncture of the interatrial septum (IAS) using a transseptal needle. A 2nd access can again be gained via PFO, a 2nd TP or catheter probing of the previous puncture s...
