[Catheter Isolation of Pulmonary Veins in a Patient With Paroxysmal Atrial Fibrillation After Repair of Interventricular Septum With a Xeno-Pericardial Patch].

Catheter radiofrequency ablation of focal atrial fibrillation was successfully performed in a patient after closure of interventricular septal defect with a xeno-pericardial patch and plastic of tricuspid valve. The case demonstrates feasibility of carrying out such interventions under intracardiac echocardiographic guidance in patients with disturbed anatomy and complicated access to the left atrium.
