Surgical treatment of pediatric cardiac arrhythmia
Insights
Advanced diagnostics, medications, and surgical techniques now effectively manage complex pediatric cardiac arrhythmias. Surgery is recommended for children unresponsive to or intolerant of medical treatments for symptomatic arrhythmias.
Area of Science:
- Pediatric Cardiology
- Cardiac Electrophysiology
- Cardiovascular Surgery
Background:
- Complex cardiac arrhythmias in children present significant management challenges.
- Traditional treatments include antiarrhythmia medications and, in select cases, surgical interventions.
- Advances in diagnostics and therapeutics have improved outcomes for pediatric arrhythmias.
Observation:
- Symptomatic and hemodynamically compromising arrhythmias in children are candidates for surgical evaluation.
- Comprehensive electrophysiologic testing is crucial for determining surgical suitability.
- Surgical interventions for pediatric arrhythmias are increasingly successful.
Findings:
- Improved diagnostic tools, potent antiarrhythmia drugs, and surgical advancements enable effective management.
- Patients with symptomatic arrhythmias refractory to or intolerant of medical therapy are prime candidates for surgical antiarrhythmia procedures.
- Referral to specialized pediatric cardiac centers is essential for optimal evaluation and treatment.
Implications:
- Surgical treatment for pediatric cardiac arrhythmias offers definitive and potentially curative options.
- Indications for surgical intervention may broaden with continued success.
- Surgery may be a preferable alternative to suboptimal or poorly tolerated long-term medical therapy.
Abstract:
The combination of improved diagnostic techniques, new and potent antiarrhythmia agents, and progress in antiarrhythmia surgical procedures has resulted in successful management of complex cardiac arrhythmia in children. The kinds of arrhythmia that can be considered for possible surgical intervention share several features. Each produces symptoms and usually is hemodynamically compromising. Each requires extensive preoperative and intraoperative electrophysiologic evaluation to establish the mechanism, response to drugs, and suitability for surgery. Although reports of surgical arrhythmia treatment have been limited in children, with increasing success the indications for such treatment may become less stringent. Our recommendations are shown in the Table. In general, patients intolerant of or unresponsive to medical treatment for symptomatic arrhythmia (tachycardia or bradycardia), should be considered candidates for surgical antiarrhythmia procedures. These patients should be referred for testing to cardiac centers staffed by pediatric cardiac electrophysiologists and surgeons experienced in arrhythmia diagnosis and ablation. Careful evaluation can identify those patients in whom surgical approaches are most appropriate. At present, surgical operations for selected, serious pediatric cardiac arrhythmias offer definitive and possibly curative treatment, and may be preferable to inadequate, poorly tolerated, or long-term medical therapy.
