Brief Summary

Implantable cardiac defibrillators (ICDs) are devices that are put into patients at high risk of sudden cardiac death. They are used to treat life threatening heart rhythm disorders. They have conventionally consisted of a generator sitting under the skin of the chest and leads which pass from veins in the collar bone region to the heart. Problems with these devices can necessitate extraction, with the commonest reason being infection. If extraction is required for infection then re-implantation is usually deferred for approximately one week whilst antibiotics are given so that the risk of infection of the new device can be minimised. This has considerable implications for healthcare resources. A new ICD has been developed that is entirely subcutaneous with no intravenous element. It is already in clinical use and is positioned remote from conventional ICD sites. With no intravenous element there is very little risk of infection in the blood affecting the new device. It is therefore likely to be possible to re-implant these devices immediately after extracting a conventional system. The aim of this research is to assess the outcome in patients re-implanted with this device immediately after conventional ICD system extraction. This data will be compared compared to those who have conventional systems re-implanted after the necessary delay.
