Transseptal puncture in patients with intracardiac devices
Thirty-six procedures (6.1%) with 51 TSPs were performed in the presence of CIED (28 TSPs in single chamber devices, 21 TSPs in dual chamber devices and 2 TSPs in cardiac resynchronization device). One patient (1/51 punctures, 2%) with a dual chamber device had procedure related dislocation of the ventricular lead that occurred at the time of achieving single transseptal access for VT ablation. There were no other lead dislocations and no changes in lead parameters according to pre and post-procedural device interrogations.
