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.

AbstractA 2-month-old baby was resuscitated from ventricular fibrillation attributed to a concurrent chaotic atrial tachycardia with Wolff-Parkinson-White syndrome. He underwent successful radiofrequency catheter ablation of an accessory pathway. Throughout the 4-year follow-up after the procedure, the boy remained free of any drugs, was in sinus rhythm without ventricular pre-excitation and his growth and development were normal.

Supraventricular Tachyarrhythmias

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.

Supraventricular Tachycardias

Pharmacological therapy is mostly employed in the management of supraventricular tachyarrhythmias in different part of the world including Bangladesh. However, Radiofrequency catheter ablation has been found to be highly effective and safe in the treatment of such tachyarrhythmias. Objective: The current study is aimed at sharing our experiences of 842 patients who presented with Supraventricular tachycardias and were diagnosed by EPS and treated with Radiofrequency catheter ablation. Methods: This descriptive study has been carried out in the cardiac electro physiology Department of NICVD, Dhaka, Bangladesh from 2nd January 2015 to 31st December, 2020. Electrophysiology study(EPS) was carried out to identity and diagnose the mechanism of different SVTs in 842 consecutive patients. RF catheter ablation was used to interrupt the tachycardia circuit. Results: Out of a total 842 patients who underwent Electrophysiology study, 435 were found to have atrioventricular nodal re-entry tachycardia (AVNRT) as underlying mechanism and 391 were having accessory pathway responsible for the reentry mechanism; of these accessory mediated tachycardia, 250 patients were manifested accessory pathway (WPWS); 141 were concealed accessory pathway (out of them 365 were presented with orthodromic and 26 as antidromic reciprocating tachycardia); moreover among the accessory pathway 231 patients were found having left sided accessory pathway whereas 155 having right sided pathway; 12 patients were having focal atrial tachycardia and 4 were found atrial flutter as the underlying cause for SVT. Radiofrequency catheter ablation was used with an overall success rate of 95%, recurrence rate of 2% without any significant complication. Complication: One patient developed pulmonary thrombo-embolism, 6 patients developed DVT of right lower limb, 4 patients developed complete heart block. Conclusion: RF catheter ablation is safe and highly effective mode of treatment of different types of supraventricular tachyarrhythmias which is emerging and becoming popular in our country.

Atrial Remodelling

With catheter ablation becoming effective for non-pharmacological management of AF, many cases of atrial tachycardia (AT) after AF ablation have been reported in the past decade. These arrhythmias are often symptomatic and respond poorly to medical therapy. Post-AF-ablation ATs can be classified into the following three categories: focal, macroreentrant and microreentrant ATs. Mapping these ATs is challenging because of atrial remodelling and its complex mechanisms, such as double ATs and multiple-loop ATs. High-density mapping can achieve precise identification of the circuits and critical isthmuses of ATs and improve the efficacy of catheter ablation. The purpose of this article is to review the mechanisms, mapping and ablation strategy, and outcome of ATs after AF ablation.

Focal atrial tachycardia (AT) is a relatively uncommon cause of supraventricular tachycardia, but when present is frequently difficult to treat medically. Atrial tachycardias tend to originate from anatomically determined atrial sites. The P-wave morphology on surface electrocardiogram (ECG) together with more sophisticated contemporary mapping techniques facilitates precise localisation and ablation of these ectopic foci. Catheter ablation of focal AT is associated with high long-term success and may be viewed as a primary treatment strategy in symptomatic patients.

Surveillance Analysis

A recent surveillance analysis indicates that cardiac arrest/death occurs in ≈1:50,000 professional or semi-professional athletes, and the most common cause is attributable to life-threatening ventricular arrhythmias (VAs). It is critically important to diagnose any inherited/acquired cardiac disease, including coronary artery disease, since it frequently represents the arrhythmogenic substrate in a substantial part of the athletes presenting with major VAs. New insights indicate that athletes develop a specific electro-anatomical remodeling, with peculiar anatomic distribution and VAs patterns. However, because of the scarcity of clinical data concerning the natural history of VAs in sports performers, there are no dedicated recommendations for VA ablation. The treatment remains at the mercy of several individual factors, including the type of VA, the athlete’s age, and the operator’s expertise. With the present review, we aimed to illustrate the prevalence, electrocardiographic (ECG) features, and imaging correlations of the most common VAs in athletes, focusing on etiology, outcomes, and sports eligibility after catheter ablation.
