Article Information

Background: The complex CIED implant and follow-up service was started at Croydon University Hospital (CUH) in November 2012. The service is currently supported by 3 consultants, 2 arrhythmia nurse specialists and 4 specialised cardiac physiologists and received a favourable report following an accreditation visit by NHS England in 2015.

We reviewed the complex CIED implantation service from April 1 2013 to March 31 2019 examining:

  • rates of implantation;
  • compliance with national and international guidelines; and
  • mortality and complication rates at 12 months.

MethodologyData was collated from prospectively collected records for all CIED cases implanted at CUH. Complex CIED implants were defined by new or upgrade ICD or CRT implants.

ResultsFrom 1 April 2013–31 March 2019 120 ICDs & 230 CRT were implanted. An LV lead was successfully deployed in 227/230 cases (98%). The mean age at implantation was 72 years (range 24–95 years); the M: F ratio was 3:1.

The chart below illustrates the annual number of complex CIED implants and the overall rate of complications for the 5-year period from 1 April 2013–31 March 2018.

During this 5-year period, the all-cause 12-month mortality was 10% (29/283). Of the 350 cases in which the implantation of a complex CIED was undertaken, 339 (97%) met NICE, ESC or HRS guidelines (1, 2, 3, 4, 5, 6).


  • Committed DGHs can establish and maintain high-quality complex CIED services, which meet the standards expected by national organisations such as NHSE and BHRS (7).
  • Using compliance with Guidelines and 12-month mortality as surrogate markers of appropriate patient selection we demonstrated that a well-considered complex CIED service can be delivered in DGHs.
  • It is recognised that complications after the implantation of complex CIED occur more frequently than is generally acknowledged, with figures quoted often being derived from randomised controlled trials. However, publications are emerging from registry data suggesting higher complication rates in the “real-world”. Our complication rate over a 5 year-period of 8.5% is in keeping with this published data (8). This issue is especially relevant in the current era of progressing towards Shared Decision Making and conveying information to our patients which accurately informs the conversation.
