On the 13 November 2018, Rui Providencia, the Co-ordinating Editor of the Heart Group was present at a Patient Information / Counselling Session at St. Bartholomew's Hospital (London, UK) for patients who were candidates for Implantable Cardioverter Defibrillators. Rui discussed the indications for this technology, potential benefits and complications. Part of the discussion also involved the new sub-cutaneous ICD and its differences vs. the standard transvenous lead models. This part of the talk was of interest to the audience who asked several questions about the potential pros and cons of this technology. For that reason, and as we believe this is an area where a systematic review might be of benefit, are we announcing a vacant title.
