Implication

May support ablation in refractory ectopic atrial tachycardia with cardiomyopathy reversal; hypothesis-generating and requires prospective validation.

Structured PICO

Does radiofrequency catheter ablation improve symptoms and reverse cardiomyopathy in patients with refractory ectopic atrial tachycardia?

Population

5 patients (4 adults aged 20-56 years, and one 6-year-old boy) with refractory ectopic atrial tachycardia (EAT). Four patients had heart failure and three had depressed LV function by echocardiographic criteria.

Intervention

Radiofrequency (RF) catheter ablation

Outcome

Reversal of tachycardia-induced cardiomyopathy (reduction in chamber size and recovery in systolic function by echocardiography)surrogate

Radiofrequency catheter ablation is a safe and effective therapy for refractory ectopic atrial tachycardia that can successfully reverse tachycardia-induced cardiomyopathy.
