Case report: The case of a 40-year-old woman with paroxysmal symptomatic atrial fibrillation and implanted occluder of a patent foramen ovale (PFO; AMPLATZER™ Septal Occluder, St. Jude Medical) is reported. Due to the symptomic atrial fibrillation, pulmonary vein isolation was planned.
Methods: Under transesophageal, echocardiographic control the transseptal puncture was performed posterior inferior of the occluder without any complications. The pulmonary vein was successfully isolatedusing radiofrequency energy.
Conclusion: This case demonstrates that transseptal puncture in pulmonary vein isolation with an inserted PFO occluder under additional transesophageal, echocardiographic monitoring is safe and feasible.
