[Acute myocardial infarction complicating radiofrequency catheter ablation in a girl]

Paroxysmal supraventricular tachycardia is the most common tachyarrhythmia in childhood and adolescence. The current treatment of choice for managing and preventing frequent recurrences is radiofrequency catheter ablation, which provides a definitive solution in most cases. This technique is very effective but not devoid of potential complications, particularly in children and adolescents. We report the case of a 3-year-old girl who suffered acute myocardial infarction after occlusion of the right coronary artery during this procedure. We describe intraoperative and postoperative management. Progress was good and the patient was discharged 14 days after ablation.
