Unstructured Abstract
Compared to fluoroscopy, intracardiac echocardiography (ICE) provides better anatomical visualization and early recognition of complications related to transseptal puncture (TSP). A total of 949 ICE-guided TSPs (586 fluoroless left-sided arrhythmia procedures) performed in adult and pediatric patients were retrospectively analyzed. With a 99.8% success rate and only 1 transseptal access related pericardial tamponade (0.2%), entirely ICE-guided TSP can be successfully and safely performed in fluoroless CA of left-sided arrhythmias. As 1 lead dislocation was recorded following TSP caution is advised in patients with intracardiac electronic devices.
