Popis: Introduction Multiple studies showed no clinical benefit in implantation of a dual compared to a single chamber implantable cardioverter defibrillator (dICD vs. sICD) for primary prevention of sudden cardiac death (SCD), in patients with no pacing indication. We aimed to investigate the extent of utilization and complications in sICD vs. dICD implantations in the US, using the National In-Patient Sample (NIS) database. Methods Using the NIS database, we identified patients who underwent an elective ICD implantation in the US between 2015 (last quarter)-2019. Patients who had concurrent conduction disorders or indication for atrial pacing were excluded. Baseline demographics, clinical characteristics, cardiomyopathy etiologies as well as outcomes including in-hospital complications, length of stay and mortality were collected. Multivariable logistic regression models were used to identify predictors of complications. Results and discussion An estimated total of 15940 patients, who underwent elective ICD implantation for primary prevention of SCD were identified, 8860 (55.6%) of them received a dICD. Forty percent of patients had ischemic cardiomyopathy. The mean age was 64 years and 66% were males. The complication rates documented in the dICD and sICD groups were 13% and 11%, respectively (p Conclusion Despite significant evidence for lack of clinical benefit in adding an atrial lead to a primary prevention ICD implantation, significant proportion of the patients in the US are implanted with a dICD. We show increased risk for complications for dICD compared with sICD implantation in the US in recent years, driven by higher incidence of pneumo/hemothorax and lead dislodgement.
