“…The mean procedure, fluoroscopy and radiofrequency energy exposure durations were 104±39 minutes (45-195), 24±10 minutes and 191±90 seconds , respectively. Mean follow-up period was 4.8±3.2 years (1)(2)(3)(4)(5)(6)(7)(8)(9)(10). Mean values for pre-RFA left ventricular end-diastolic diameter (LVEDD) and left ventricular ejection fraction (LVEF) were 49.1±9.6 mm and 40.8±13.4% (23-57%), respectively.…”

“…Tachycardia-induced cardiomyopathy, which results in a clinical feature of heart failure, is characterized by the development of ventricular systolic and/or diastolic dysfunction and ventricular dilatation in the presence of rapid and/or irregular ventricular rhythm, all of which is partially or completely resolve following normalization of heart rate (3)(4)(5). The reversibility of symptoms and cardiac functions in patients with TIC highlights the need for pursuit of an aggressive treatment approach.…”

Objective: Tachycardia-induced cardiomyopathy (TIC) is a rare but potentially curable cause of dilated cardiomyopathy. Data on radiofrequency ablation (RFA) for TIC is limited. The aim of this study is to present our experience with RFA in children with TIC, retrospectively. Methods: The medical records of patients with TIC and those underwent RFA between 2000-2011 were systematically reviewed. Demographics and echocardiographic features were recorded. Tachycardia-induced cardiomyopathy is defined as dilatation of the heart chambers or heart failure with chronic or very frequent cardiac arrhythmia. Diagnosis was confirmed with normalization of functions after sinus rhythm has been achieved. Results: A total of 12 patients with a mean age of 6.3±4.1 years (in utero-11.5 years) at diagnosis were enrolled in the study consisting of 7 patients with permanent junctional reciprocating tachycardia and 5 patients with focal atrial tachycardia. The mean pre-RFA left ventricular end-diastolic diameter and left ventricular ejection fraction (LVEF) values were 49.1±9.6 mm (32-66) and 40.8±13.4% (23-57%), respectively. One month after RFA, the mean LVEF value was 62±4.9% (52-69), with only 2 out of 12 patients' LVEF values were still lower than 58%. Tachycardia recurrence was observed in 4 patients, 3 of which had successful repeated RFA procedure. Overall, cure for arrhythmia was achieved in 11 patients (92%), while reversal of heart failure achieved in all patients. In 1 patient permanent complete AV block was developed after the procedure. Conclusion: Treatment of tachycardia with RFA, particularly in patients with arrhythmia refractory to medical therapy, is a feasible and effective treatment option regardless of age.

“…Although the true incidence is not known, it is generally accepted as being uncommon. It may occur at any age -from intrauterine through adult life -and has been associated with other concomitant conditions, including postheart transplantation (162). When should I suspect it?…”

“…It is considered to be a potentially reversible cause of heart failure. With appropriate heart rate and/or rhythm control, clinical, hemodynamic and structural parameters may normalize in as early as four weeks (160,(162)(163)(164)(165). Treatment of heart failure should follow the CCS heart failure guidelines (5), with additional emphasis on correcting and controlling the underlying causative rhythm.…”

“…Tachycardia‐induced cardiomyopathy (TIC) due to atrial fibrillation (AF) occurs particularly often 1, 2, 3. Although catheter ablation is effective therapy for congestive heart failure (CHF) with AF 4, 5, it might be avoided in patients with a severely depressed left ventricular (LV) systolic function because of the possibility of coexisting primary idiopathic dilated cardiomyopathy with AF 1, 6.…”

Key Clinical MessageWe describe the case that persistent atrial fibrillation refractory to rhythm control by pharmacotherapy and electrical cardioversions caused tachycardia‐induced cardiomyopathy with low ejection fraction and hemodynamic instability. Mechanical hemodynamic support using an intra‐aortic balloon pump is one of the choices of hemodynamic support during catheter ablation by pulmonary vein isolation.
