Tetralogy of Fallot Atrial Arrhythmias Medication, Mapping and Ablation - De Groot

Video Transcription

Video Summary

The presentation discusses atrial arrhythmias in patients with tetralogy of Fallot, highlighting risks such as sinus node dysfunction, atrioventricular conduction block, ventricular and atrial arrhythmias including atrial fibrillation. Management options include antiarrhythmic drugs, electrical cardioversion, overdrive pacing, and ablation therapy using advanced mapping systems to identify scar tissue and target areas for treatment. Studies have shown older age at repair and tricuspid regurgitation as risk factors for atrial flutter and fibrillation. Ablation therapy has shown potential as a curative treatment, with success rates ranging from 70-80%, though the mechanisms of atrial fibrillation in tetralogy of Fallot patients remain unclear. More research is needed to understand triggers, substrates, and optimize treatment strategies for this patient population.
