Wearable cardioverter-defibrillators (WCDs) offer temporary protection against sudden cardiac death (SCD) for at-risk patients. While safe and effective, further trials are needed to confirm long-term survival benefits and cost-effectiveness.
Area of Science:
- Cardiology
- Medical Devices
- Electrophysiology
Background:
- Sudden cardiac death (SCD) prevention is a critical cardiology concern.
- Implantable cardioverter-defibrillators (ICDs) have proven successful, but transient risk profiles necessitate alternative solutions.
- Wearable cardioverter-defibrillators (WCDs) provide a non-invasive option for temporary SCD risk management.
Approach:
- This review synthesizes current data on WCD usage, safety, and efficacy.
- It examines specific indications and potential risks associated with WCD therapy.
- The review highlights the role of WCDs in facilitating risk stratification for long-term SCD risk.
Key Points:
- WCDs are effective for temporary SCD prevention in selected patient groups.
- They offer a crucial window for comprehensive risk assessment.
- Current evidence supports WCD safety and efficacy, though mortality benefit data from randomized trials are pending.
Conclusions:
- WCDs represent an adequate and safe temporary measure for SCD prevention.
- Further prospective randomized trials are essential to establish prognostic relevance and economic value.
- WCDs aid in identifying patients requiring long-term SCD management strategies.
