Important contributions to the field

We have been at the forefront of innovation in the field of pediatric and congenital arrhythmias since its inception.

We were among the first to apply principles of cardiac pacing and catheter ablation in children, and our breakthrough work in these basic interventional techniques are now applied worldwide to children with arrhythmic disease.

Our program has more than 40 years of experience in cardiac pacing and defibrillation and 25 years in catheter ablation. 

We are well known as innovators in the fields of ablation and arrhythmia management in patients with congenital heart disease, the development of hybrid pacing and defibrillation systems, lead extraction techniques relevant to our patients, and techniques for reducing fluoroscopy in catheter ablation in all patients.

Publications

We are leaders in pediatric electrophysiology research, having over 200 publications dating back 25 years. Our research publications are listed below.
