Implantable Cardiac Defibrillator (ICD) generator replacement decisions are often complex. Changes in clinical status, patient opinion regarding generator change and presence of ICD shocks are vital in this decision process. We studied whether the presence or absence of ICD shocks influences patients’ perception of their ICDs, placed either for primary (PP) or secondary (SP) prevention.
Data were collected from 10/2010 to 10/2011. A simple questionnaire was administered to patients who presented for ICD generator replacement, to assess their knowledge and perspective regarding function and benefits of their ICDs. All ICDs were interrogated to evaluate for shocks delivered.
60 patients were enrolled (age 68 ± 13, 70% male, 66.7% PP). Shocks occurred in 51% of all patients. Among the shocks delivered, in the PP group, 65% were appropriate and 35% inappropriate, while in the SP group, 100% were appropriate. There was a trend towards patients with inappropriate shocks being less satisfied and knowledgeable compared to those with appropriate shocks, but overall there was no significant difference in response, between patients in PP or SP groups or in patients who had shocks or not.
In our cohort, decision regarding generator replacement was not influenced by the prevalence of appropriate, inappropriate or absence of ICD shocks. Improved patient education regarding shocks may alter decision regarding generator change especially in patients who received shocks.
