What is the long-term clinical outcome and rate of ICD implantation avoidance in patients using a Wearable Cardioverter-Defibrillator?
The use of a Wearable Cardioverter-Defibrillator allows for the avoidance of permanent ICD implantation in over half of patients, with good long-term survival and low rates of subsequent shocks.
Following WCD use, ICD implantation could be avoided in 58% of patients. Long-term follow-up shows good overall survival. The majority of all patients did not suffer from WCD shocks nor did receive ICD shocks after subsequent implantation. Patient selection regarding predictive conditions on long-term risk of ventricular tachyarrhythmias needs further risk stratification.
