In case of cardiac involvement, it is called cardiac amyloidosis (CA), which has a poor prognosis and causes sudden cardiac death (SCD). An implantable cardioverter defibrillator (ICD) prevents SCD due to ventricular tachyarrhythmia; however, ICD implantation in patients with CA is controversial because of the poor prognosis of CA and the possibility of pulseless electrical activity. This study is a systematic review aimed to evaluate the efficacy of ICD in patients with CA.: Methods: A systematic literature review was conducted in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines (PRISMA). On June 30, 2019, a comprehensive literature search of Medline, PubMed, Embase, CINAHL and the Cochrane Library was performed. Longitudinal observational studies of patients with CA with implanted ICD were included. Primary outcomes were appropriate ICD therapy, all-cause mortality and one-year survival.: Results: Nine studies with a total of 704 CA patients with implanted ICD were included. The median incidence rate of appropriate ICD therapy was 26.0% (range 6.5-28.3%) of the patients during 21.5 (0-175) months of follow-up period. All-cause mortality was observed in 96 (41.3%) among 232 patients and median one-year survival was 79% (range 39-92%).: Conclusions: Patients with CA benefit from ICD implantation considering the incidence rate of appropriate ICD therapy and one-year survival. There is no evidence that ICD implantation can: 9: improve patients’ prognosis. Larger studies are needed to elucidate the impact of ICD on patients with CA and to develop selection criteria for implantation.}, title = {The Effectiveness of a Cardioverter Defibrillator in Patients with Cardiac Amyloidosis: A systematic literature review}, year = {}, yomi = {トキオカ, サユリ} }
