The Australian and New Zealand cardiac pacemaker and implantable cardioverter-defibrillator survey: calendar year 2013

Abstract

Background: A pacemaker (PM) and implantable cardioverter-defibrillator (ICD) survey was undertaken in Australia and New Zealand for calendar year 2013.

Results and conclusions: For 2013, PMs sold as new implants in Australia was 15,203 (12,523 in 2009) and implanted in New Zealand were 1,641 (1,277 in 2009). The number of new PM implants per million population 652 for Australia (565 were in 2009) and 367 for New Zealand (299 in 2009). Although PM replacements rose in New Zealand, there was a fall in Australia as a result of improved power source service life. Pulse generator types sold in Australia were predominantly dual chamber 74% (71% in 2009) and implanted in New Zealand 59% (54% in 2009). There were 661 biventricular PMs implanted in Australia (446 in 2009) and 83 in New Zealand (45 in 2009). Transvenous pacing leads were overwhelmingly bipolar with preferences for active fixation leads, although, since 2009, there has been a minor resurgence in Australia of passive fixation lead usage in the atrium from 20 to ∼24%. There was also a marked increase in the ICD implants with 3904 new implants in Australia (3555 in 2009) and 423 in New Zealand (329 in 2009). The new ICD implants per million population were 167 for Australia (160 in 2009) and 95 for New Zealand (77 in 2009). Biventricular ICD implants increased significantly in both Australia (2211) and New Zealand (118).
