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.
