'Disappeared balloon': the trap of transseptal puncture for a large closure device of atrial septal defect-a case report.

ABSTRACT:

Background

Several studies have demonstrated a notable increase in the incidence of atrial arrhythmias among individuals with atrial septal defect (ASD) occluder. Although the sequential dilation technique has been proposed as the mainstream technique for transseptal puncture with ASD occluder, it is associated with substantial risks and technical difficulties.

Case summary

We report a patient who underwent catheter ablation for atrial fibrillation and had a large ASD occluder. A balloon was dislodged into the patient's right superior pulmonary vein (RSPV) during a transseptal puncture and was successfully captured. The most notable feature of this case was the dislodgement of the dilation balloon, which has not been reported previously.

Discussion

Repeated and gradua
