Key result
Ablation successfully suppressed adenosine-sensitive atrial tachycardia originating from the anterior mitral annulus by mapping the full circuit, despite a shift in tachycardia origin.
Case Report (n=1)
In adenosine-sensitive atrial tachycardia, precise mapping is essential because ablating the earliest activation site may only modify the exit rather than the critical slow conduction zone.
No takes yet. Share an insight, caveat, or question.
May warrant full-circuit mapping in adenosine-sensitive mitral annular AT to avoid exit modification; hypothesis-generating and leaves open prospective validation.
Inagaki et al. (2018) conducted a case report in Adenosine-sensitive atrial tachycardia (n=1). Ablation was evaluated on Suppression of atrial tachycardia. Ablation successfully suppressed adenosine-sensitive atrial tachycardia originating from the anterior mitral annulus by mapping the full circuit, despite a shift in tachycardia origin.
