Secondary prevention of sudden cardiac death in the young patient with arrhythmogenic right ventricular cardiomyopathy and hemodynamically tolerated ventricular tachycardia is still a challenging field. We present a combined approach, including subcutaneous implantable cardioverter-defibrillator (ICD) and catheter ablation, as a promising treatment to prevent both ventricular tachycardia recurrences and ICD shocks. (Level of Difficulty: Intermediate.).
RESUMO
: Twiddler's syndrome is an uncommon cause of cardiac implantable electronic device malfunction, usually due to manipulation of the pulse generator. A few spontaneous cases have already been described. We present the unique case of a 77-year-old woman who experienced iatrogenic Twiddler's syndrome.

Arrhythmia-induced cardiomyopathy is a partially or completely reversible form of myocardial dysfunction due to sustained supraventricular and ventricular arrhythmias. Asynchrony, rapid cardiac rates and rhythm irregularities are the main factors involved in the development of the disease. The reversible nature of arrhythmia-induced cardiac dysfunction allows only for a retrospective diagnosis of the disease once cardiac function is restored following heart rate control. A high level of suspicion is needed to make a diagnosis at an early stage and prevent further progression of the disease. Although reversible, arrhythmia-induced cellular and molecular changes may remain, increasing the risk for sudden death even when normal ejection fraction is restored as well as causing rapid deterioration of cardiac function and development of heart failure symptoms if arrhythmia recurs. Appropriate management based on a combination of pharmacologic and nonpharmacologic strategies to achieve rate control and prevent arrhythmia recurrence is pivotal to avoid further cardiac function deterioration and to control symptoms, significantly reducing the risk of heart failure and sudden cardiac death.
