Pulse Generator Replacement

Pulse Generator Replacement

 

One retrospective analysis of ICD advisories in Canada reported an 18.3% replacement rate, and subsequent 8.1% complication rate directly related to the replacement. Device replacements also occur in order to upgrade an existing system. Clinical studies have shown that cardiac resynchronization therapy (CRT) significantly reduces all-cause mortality and hospitalization in patients with advanced heart failure (HF). As a result of expanding indications for this therapy, many standard ICD patients are being upgraded to CRT-D systems. Complication rates related to upgrades of these systems are also not widely known. To our knowledge, the risk of complications following a device replacement has not been studied prospectively in any patient population. Limited data are available to guide physicians when weighing the risks and benefits of device replacement.This is a prospective multi-center study. 1750 patients at 100 clinical sites will be enrolled prior to generator replacement. Patients will be implanted and followed for 6 months to assess any complications related to the replacement procedure. Patients with any legally marketed device for explant can be enrolled. The replacement device can be from any manufacturer
