Transseptal catheter ablation of the slow pathway is a feasible and safe alternative for patients with AVNRT and atypical post-operative anatomy from surgically corrected partial AV canal defect.
May support transseptal ablation in post-surgical AVNRT anatomy; single case leaves open generalizability and prospective validation.
A 26-year-old woman with partial atrioventricular (AV) canal defect surgically closed with pericardial patch in a mode that the triangle of Koch had become part of the left atrium underwent successful slow pathway ablation for slow-fast AV nodal reentrant tachycardia. Transseptal approach was used because of the atypical post-operative anatomy. Transseptal catheter ablation of the slow pathway can be a reasonable and safe alternative in patients subjected to this type of operation.
