Abstract presented at poster session of the 7th World Congress of Pediatric Cardiology & Cardiac Surgery, Barcelona, Spain (July 2017): P1383 – Real Time Three Dimensional Echocardiography guided Electrophysiological Procedures in Pediatric Patients. Cardiology in the Young, 2017;27:S199. doi:10.1017/ S104795111700110X.

Electrophysiological studies and interventions often require access to anatomic locations that are difficult to visualize with conventional imaging methods. Real-time three-dimensional echocardiography (RT3DTEE) has revolutionized interventional procedures by providing accurate visualization of cardiovascular structures. The 3D depth perception offered by RT3DTEE greatly facilitates the intraprocedural guidance of catheters and localization of arrhythmogenic substrates. We discuss the utility of RT3DTEE for guiding catheter ablation of premature ventricular contractions arising from the perimembranous region of the ventricular septum. The approach to a left ventricular outflow tract focus through the right atrium and left ventricle is also described.
