Spanish implantable cardioverter-defibrillator registry. 20th official report of the Heart Rhythm Association of the Spanish Society of Cardiology (2023)

Introduction: This article presents data on implantable cardioverter-defibrillator implants in Spain in 2023.

Methods: The registry is based on information provided by centers following device implantation, which is submitted to the Heart Rhythm Association of the Spanish Society of Cardiology via the national online registry platform (Cardiodispositivos). Additional information sources include: a) data transfer from the manufacturing and marketing industry; and b) local databases sent from the implanting centers. Population data from the National Institute of Statistics for the first quarter of 2024 was used to calculate implant rates.

Results: In 2023, 180 hospitals participated in the registry. Data were reported for 8219 units, compared with 8523 reported by Eucomed (European Confederation of Medical Suppliers Associations). The total implant rate was 172 implants per million inhabitants (177 according to Eucomed), representing an increase compared with previous years. However, differences among autonomous communities persisted, and Spain continues to have the lowest implant rate among the European countries participating in Eucomed.

Conclusions: The data from the 2023 registry reflects 96.4% of the implants performed in Spain. Despite the improvement observed in the implantation rate, Spain's position in Europe remains unchanged, with wide disparities among autonomous communities.
