Observing the effectiveness of pacing therapy for congenital heart disease patients with atrial arrhythmias

ATrial Tachycardia PAcing Therapy in Congenital Heart

Observational University of Iowa · NCT03209583

This study is testing how well pacing therapy works for people with congenital heart disease who have heart rhythm problems and already have devices to help manage them.

What this trial studies

This observational study aims to evaluate the effectiveness of atrial tachycardia pacing (ATP) therapy in patients with congenital heart disease (CHD) who have implanted atrial tachycardia devices (ATDs). The research will involve both retrospective and prospective data collection from a minimum of 250 subjects across multiple institutions. The study will focus on how well ATP works in managing atrial arrhythmias, particularly in patients who have undergone surgical interventions for CHD. No active interventions will be performed, as the study will primarily analyze existing patient data.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals with structural congenital heart disease, an atrial arrhythmia, and an implanted atrial tachycardia device with ATP activated.

Not a fit: Patients with other arrhythmia substrates or those who have undergone transplant, surgical maze, or ablation within the last five years may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the management of atrial arrhythmias in patients with congenital heart disease, potentially reducing morbidity and mortality.

How similar studies have performed: While there have been studies on atrial arrhythmias in congenital heart disease, this specific approach to evaluating ATP therapy in a multi-institutional observational setting is relatively novel.
