Complications from implantable cardioverter-defibrillators (ICDs) occurred in 32% of patients, with inappropriate shocks being the most common issue. Overall, major adverse events were infrequent, aligning with findings from other research centers.

Area of Science:

  • Cardiology
  • Medical Devices
  • Electrophysiology

Background:

  • Implantable cardioverter-defibrillators (ICDs) are crucial for treating malignant ventricular arrhythmias.
  • ICD implantation carries risks of early and late complications, necessitating careful patient selection.
  • Understanding complication incidence is vital for optimizing patient care and device management.

Purpose of the Study:

  • To determine the incidence of early and late complications associated with ICD implantation in a specific patient cohort.
  • To compare observed complication rates with those reported in existing literature.

Main Methods:

  • A retrospective analysis of 98 patients who received an ICD.
  • Data collection on procedural and device-related complications.

  • Comparison of findings with published data from other studies.

    • Main Results:

    • A 32% complication rate was observed in the study population.
    • Inappropriate shocks were the most frequent complication (13%), followed by infection (4%) and lead insulation faults (5%).
    • Device inefficacy (5%), syncope (2%), and a 13% overall mortality rate (3% sudden death) were also noted during a mean follow-up of 2.9 years.

    Conclusions:

    • Major complications related to ICDs were found to be relatively uncommon in this patient group.
    • The study's findings are consistent with complication rates reported by other international centers.
    • These results support the continued use of ICDs while emphasizing the importance of monitoring for potential adverse events.
