Late-Onset Perinodal Atrial Tachycardia After Transcatheter Atrial Septal Device Closure

Key Result

Noncoronary cusp ablation provides a safe treatment option for perinodal focal atrial tachycardia occurring late after transcatheter atrial septal device closure.

Key Points

• This research aims to explore the occurrence of late-onset atrial tachycardia following atrial septal defect closure and evaluate treatment options.
• Examined instances of atrial tachycardia after atrial septal device closure
• Evaluated the safety of noncoronary cusp ablation for treating these cases
• Late-onset atrial tachycardia can arise long after ASD closure
• Noncoronary cusp ablation is a safe and effective intervention for managing perinodal foci.
