Decision regret in implantable cardioverter-defibrillator recipients : A cross-sectional analysis on patients that regret their decision after ICD implantation.

Background: Implantable cardioverter-defibrillators (ICDs) are designed to deliver therapy in the event of malignant ventricular arrhythmias. Despite their benefits, some ICD recipients regret their decision on device implantation.

Objectives: The aim of this study was to evaluate the incidence, predictors, and consequences of recipients that regretted their decision after implantation.

Methods: A questionnaire-based cross-sectional survey of consecutive ICD recipients examined during a routine outpatient follow-up visit was conducted. Their level of depression and anxiety was assessed with the hospital anxiety and depression scale (HADS). Quality of life (QOL) was assessed using the Minnesota living with heart failure questionnaire.

Results: Of 434 ICD recipients invited to the study, 423 (97.5%) agreed and completed the survey, 349 (83%) had a primary prevention indication, and 339 (80%) ischemic cardiomyopathy. A total of 41 recipients (9.7%) regretted their decision to undergo ICD implantation. These patients were: (1) younger (63 versus 69 years), (2) more frequently in New York Heart Association (NYHA) ≥2 functional class (63% versus 22%), (3) had higher education levels (more than high-school: 76% versus 60%), (4) felt that preoperative information was lacking (22% versus 4%), (5) had more complications in the perioperative period (15% versus 3%), (6) felt less safe after ICD implantation (54% versus 5%), and (7) considered more frequently ICD deactivation during near end-of-life situations (54% versus 29%). Mean QOL and HADS scores were significantly worse in these patients (36 versus 30 and 12 versus 8.8 points, respectively; p < 0.01 for all).

Conclusion: Almost 10% of ICD recipients regretted their decision after implantation. Predictors included younger age, higher education levels, complicated perioperative period, and lack of preoperative information.
