Key result
Low-power short-duration RF ablation terminates rare focal atrial tachycardia arising from the middle cardiac vein.
Why the study?
The middle cardiac vein is a rare origin site for focal atrial tachycardia.
Does low power and short-duration radiofrequency ablation effectively treat focal atrial tachycardia arising from the proximal middle cardiac vein?
Population
A 20-year-old woman with recurrent supraventricular tachycardia for 1 year and no structural heart disease
Comparison
Low-power and short radiofrequency ablation

May support low-power ablation for this rare arrhythmia; hypothesis-generating and should not yet change practice.

Does low power and short-duration radiofrequency ablation effectively treat focal atrial tachycardia arising from the proximal middle cardiac vein?
Low power and short-duration radiofrequency ablation can effectively treat rare focal atrial tachycardia originating from the proximal middle cardiac vein.
Guo et al. (2023) conducted a case report in Focal atrial tachycardia (n=1). Radiofrequency (RF) ablation was evaluated on Termination of tachycardia and non-inducibility. Low power and short-duration radiofrequency ablation successfully terminated a rare focal atrial tachycardia arising from the proximal middle cardiac vein in a 20-year-old woman.
