The patient remained hemodynamically stable during prolonged ventricular fibrillation but experienced traumatic ICD shocks, leading to deactivation of the ICD shock function and eventually LVAD deactivation and death.

Overview

Routine use of ICD shock therapy in LVAD patients should be reconsidered, as they can remain hemodynamically stable during ventricular arrhythmias, making shocks unnecessarily painful.

Key Points

  • To explore the clinical significance of ventricular fibrillation and ICD shocks in a patient with LVAD.
  • Detailed case presentation of a 71-year-old patient with dilated cardiomyopathy and an LVAD.
  • Treatment with intravenous antiarrhythmic drugs and external defibrillation was employed.
  • ICD shock function was adjusted post-treatment.
  • Patient experienced multiple painful ICD shocks associated with ongoing ventricular fibrillation.
  • Hemodynamically stable during episodes of ventricular fibrillation for prolonged periods.
  • ICD shocks were deemed traumatic, leading to a reevaluation of treatment protocols.

Structured PICO

P
Population
A 71-year-old female patient with a history of dilated cardiomyopathy caused by a phospholamban (PLN) gain-of-function mutation, with a primary prevention ICD and an LVAD.
I
Intervention
Deactivation of ICD shock function and management of incessant ventricular fibrillation.
O
Outcome
Clinical course including hemodynamic stability during ventricular fibrillation, experience of ICD shocks, and survival.

Routine use of ICD shock therapy in LVAD patients should be reconsidered, as they can remain hemodynamically stable during ventricular arrhythmias, making shocks unnecessarily painful.
