Dr Ernst is a German cardiac electrophysiologist with a special expertise in complex arrhythmias such as atrial fibrillation and ventricular arrhythmia both in paediatric and adult patients
She is one of the pioneers of remote magnetic navigation and has established this technique from its’ initiation to clinical routine using state of the art equipment including advanced 3D mapping techniques. Image integration from 3D acquisitions from magnetic resonance imaging or computed tomography assist her in performing her interventions. Especially patients with congenital heart disease, complex anatomy and drug-refractory arrhythmias are benefitting from these advances and form a major emphasis in Dr. Ernst’s clinical work. She is also a strong advocate for radiation protection measures which does not only benefit her patients but also the cath lab staff. She performs all of her procedures with low or ZERO fluoroscopy and collaborates with a number of companies to facilitate these interventions.
Atrial arrhythmias are frequently encountered in patients with congenital heart disease (CHD) (with or without corrective surgery) and respond only poorly to pharmacologic therapies. This lecture summarizes the nowadays available technologies to perform successful ablation procedures in this very complex patient cohort. Besides the understanding of the underlying anatomy, which can be supplemented by 3D imaging using magnetic resonance imaging (MRI) or computed tomography (CT), the choice of the different 3D mapping systems (sequential versus simultaneous) is presented. Finally the conventional manual navigation is compared to remote magnetic navigation and then discussed with regards to the respective arrhythmias encountered with the different CHD conditions.
