Role of catheter ablation for supraventricular tachyarrhythmias, with emphasis on atrial flutter and atrial tachycardia

We determined the clinical value of routine transthoracic echocardiography performed after catheter ablation of supraventricular tachyarrhythmias in children. Between April 1996 and December 2003, 253 children, of whom 135 male, with the overall group having a median age of 9, ranging from 0.1 to 19 years, underwent 280 uncomplicated radiofrequency catheter ablation procedures for supraventricular tachyarrhythmias at three institutions. In every child, transthoracic Doppler echocardiography was performed before and after the procedure. The pre-ablation transthoracic echocardiograms were normal in all, and this was one of the criterions for inclusion. The post-ablation echocardiogram showed a disorder in four asymptomatic patients. In one patient, with focal atrial tachycardia, ablated via a retrograde aortic approach, there was mild aortic valvar insufficiency. This had resolved 6 months later. Pericardial effusions developed in 3 other children. In 2 the effusions resolved spontaneously but 1 patient required pericardial drainage. This same patient also developed clinically asymptomatic mild aortic insufficiency, which resolved spontaneously within 6 months. Routine echocardiography after uncomplicated catheter ablation procedures is of clinical value, and is especially indicated when a retrograde aortic approach has been used.

Exercise Induced

Supraventricular tachyarrhythmias (SVTs) include atrial tachycardia (AT), atrioventricular nodal re-entrant tachycardia (AVNRT), atrioventricular re-entrant tachycardia (AVRT), atrial flutter (AFL), and atrial fibrillation (AF). The prevalence of SVT does not differ between athletes and the general population. An exception is AF, with a two- to eightfold higher prevalence in athletes, probably due to exercise-induced atrial remodelling. Symptoms of SVTs include palpitations, dizziness, weakness, and rarely syncope, and may impair athletic performance. Except for AF in the presence of an accessory pathway, SVTs are rarely life-threatening. For treatment of AT, AVNRT, AVRT, and AFL catheter ablation is generally preferred over lifelong anti-arrhythmic drug (AAD) therapy because of high rates of resolution. Reduction of training volume and AAD therapy should be attempted in athletes with AF. However, catheter ablation of AF may be the first-line therapy in athletes with severe symptoms. Most athletes with SVT can continue leisure-time activities and competitive sports.
