Abstract:
Placement of a pacing lead into a branch of the coronary sinus for biventricular pacing sometimes is difficult or impossible. Surgical completion typically has included immediate or subsequent thoracotomy lead placement with hookup to the device at the time of chest surgery. We describe an alternative procedure of complete device-lead hookup and permanent pocket closure in the electrophysiology laboratory. The left ventricular lead is an epicardial type. The lead is tunneled to a position where the surgeon subsequently can recover it using the thoracotomy incision and implant the lead on the epicardium using device-based testing.
