“…However, patients who satisfied the inclusion criteria in our study had been symptomatic for a long period and were not responsive to usual antiarrhythmic drugs. To date, the results of some successful clinical studies [12][13][14][15][16][17][18] have left several questions unanswered regarding radiofrequency catheter ablation of RVOT-PVC. Examples of these include the possibility of spontaneous remission of RVOT-PVC, RFA success predictor factors, the possibility of ablation by the epicardial route in failure cases, and the possibility of immediate relapses seen on the Holter test in the first 24 hours of the RFA.…”

SummaryObjectives: To evaluate if radiofrequency catheter ablation is an effective procedure for the treatment of right ventricular outflow tract premature ventricular contraction (RVOT-PVC) and ascertain if it results in an improvement of symptoms.Methods: A prospective study with 30 consecutive patients (mean age 40 ± 13 years, 25 females), with no apparent structural cardiopathy, with very frequent (mean density of 1,263 ± 593/h) RVOT-PVC, symptomatic for more than one year (mean = 74 months) and resistant to antiarrhythmic drugs (3 ± 1.7, including beta-blockers), who underwent radiofrequency catheter ablation.Results: After the first procedure, there were 23 initial successful cases (76.6%) and 7 initial failures (23.4%). Four patients experienced relapses, two of whom did not undergo the second procedure. The second procedure was carried out in 9 patients (7 initial failures and 2 relapses), and there was success in 5 additional patients, one of them by epicardial access. The final success rate was 80% (24/30), and there were no major complications. After a mean follow-up of 14 ± 6 months, in the successful group there was a reduction greater than 90% in density of premature ventricular contractions (PVC) (24/24; p<0.0001) and a resulting absence of symptoms in the majority of patients (23/24; p<0.001).Conclusion: Radiofrequency catheter ablation is a safe and effective treatment for patients with persistent and symptomatic PVC with RVOT morphology.

“…Other symptoms were more diverse among the patients. Intriguing symptoms were dyspnea and fatigue experienced by 18 demonstrated cases of tachycardiomyopathy secondary to RVOT-PVC, justifying intervention with RFA. In our series, we did not observe this characteristic of RVOT-PVC, which we believe to be quite uncommon.…”

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.

“…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.…”

“…In atrial fibrillation, rhythm control may require antiarrhythmic drugs or interventions, recognizing that these patients have not been studied extensively in clinical trials. Electrical control and/or electrophysiological ablation may be necessary for resistant tachyarrhythmias (163,164). Clinicians should be aware that future episodes of tachycardia may result in more rapid deterioration in systolic function and that, although infrequent, sudden cardiac death has been reported (165).…”
