What misconception about the ICD is important for patients to understand?

The misconception that is important for patients to understand is that an Implantable Cardioverter Defibrillator (ICD) cannot delay the progression of heart failure. The primary purpose of an ICD is to detect and correct life-threatening arrhythmias, not to address the underlying causes of heart failure or improve cardiac function.

Patients may have the impression that the ICD is a treatment for heart failure itself, when in fact it is a device designed to protect against sudden cardiac arrest caused by arrhythmias, which can be a complication of heart failure.

Understanding this distinction helps patients have realistic expectations about the role of the ICD in their overall treatment plan and underscores the importance of continuous management of heart failure symptoms through other means, such as medications and lifestyle changes. This knowledge is vital for their emotional and physical well-being, as they navigate their treatment journey.
