Transseptal puncture after device closure of patent foramen ovale: Is it feasible? Context: 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. 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.

This case demonstrates that transseptal puncture in pulmonary vein isolation with an inserted PFO occluder under additional transesophageal, echocardiographic monitoring is safe and feasible.
