Why the study?
Do special insertion techniques maximizing lead separation prevent lethal interactions in patients receiving combined transvenous pacemakers and implantable cardioverter-defibrillators?
Do special insertion techniques maximizing lead separation prevent lethal interactions in patients receiving combined transvenous pacemakers and implantable cardioverter-defibrillators?
Combined transvenous pacemaker and ICD insertion is feasible and safe when special techniques are used to maximize lead separation and avoid lethal device interactions.
Supports combined device insertion with lead separation in select cases; leaves open prospective trials before broader adoption.
Experience with combined transvenous pacemaker and implantable cardioverter-defibrillator insertion in 21 patients is described. Special techniques are needed to avoid potentially lethal pacemaker-implantable cardioverter-defibrillator interaction. Separation between leads for the two devices should be maximized. The electrophysiologic criteria for successful device function can be met, even when some leads for both devices must be placed by a transvenous approach.
