Introduction:
Recent reports highlighted the role of epicardial connections in the development of biatrial tachycardia circuits.
Methods:
We reported a case of 60-year-old female patient who was admitted with recurrent atrial tachycardia (AT) after endocardial pulmonary vein isolation and anterior mitral line formation.
Results:
Epicardial activation map demonstrated fragmented continuous potentials at the Bachmann's bundle region with good entrainment response. Epicardial radiofrequency ablation terminated AT with complete block in the anterior mitral line.
Conclusions:
This case corroborates the data relevant to the role of interatrial connections-specifically Bachmann's bundle-in biatrial macroreentrant ATs and demonstrates that epicardial mapping is an effective method to identify the entire reentrant circuit.
