Risk stratification for implantable cardioverter defibrillators (ICD) remains difficult due to limited data about use and outcome of device therapy in CHD patients in larger community-based cohorts. Methods and results: Out of a dataset with more than 50,000 patients registered at the German National Register for Congenital Heart Defects, 109 patients (median age 35.5; IQR 23.75–46.00), 68 (62%) male) with an ICD were identified and were retrospectively analyzed. Although the number of implantations increased steadily throughout the investigated time interval from 2001 to 2015, only 0.2% of the CHD patients in the national register received an ICD. Indication for ICD implantation was secondary prevention in 84 patients (78%) and primary prevention in 24 patients (22%). 23 patients (21%) of the ICD patients received appropriate ICD therapy. 7 patients (6%) received an inappropriate ICD therapy. In 23 patients (21%) device complications were documented with a high number of lead fractures and insulation defects (n = 14, 13%). Conclusion: The current study investigates the clinical uptake and use of ICD therapy based on a large national registry for CHD patients. Despite a steady increase in the number of implanted devices, ICD uptake remains relatively low, particularly for primary prevention. The data suggests a potential reluctance in utilization of device therapy in this patient cohort for primary prevention. Selecting patients in whom benefits outweigh the risks associated with lifelong ICD therapy remains challenging.}, DOI = {10.32604/CHD.2020.011520} }
