It is possible, but there are considerations to be aware of. Each ICD manufacturer uses proprietary components and may have unique patented therapies, resulting in differences in features such as battery longevity, size and shape, available therapies, and remote monitoring services. Switching manufacturer at replacement is not always straightforward if existing leads are to be retained.
Your cardiologist will advise on what is clinically appropriate for your individual situation and may involve the manufacturer’s clinical support team in that discussion. It is reasonable to ask about your options at your next clinic appointment.
