Medtronic Visia AF MRI / Visia AF ICD | REF DVFB1D4

The Medtronic Visia AF MRI / Visia AF ICD (REF DVFB1D4) is a single-chamber implantable cardioverter defibrillator engineered to deliver high-energy defibrillation therapy together with proprietary atrial fibrillation (AF) detection capability in a single-lead system. Designed for the management of life-threatening ventricular tachyarrhythmias, the device integrates Medtronic's PR Logic and Wavelet discrimination algorithms with AF detection diagnostics typically reserved for dual-chamber platforms, supporting clinicians in arrhythmia characterization while maintaining the simplicity of a single-chamber implant.

Key Features
- Single-chamber ICD platform with high-voltage defibrillation therapy
- AF detection diagnostics from a single ventricular lead
- SmartShock 2.0 technology to help reduce inappropriate shocks
- PR Logic and Wavelet SVT/VT discrimination algorithms
- MRI SureScan technology supporting MRI conditional scanning under specified conditions
- OptiVol fluid status monitoring (per labeled configuration)
- CareLink remote monitoring compatibility
- Programmable bradycardia pacing modes

Clinical Applications
- Primary and secondary prevention of sudden cardiac death in indicated patients
- Detection and termination of ventricular tachycardia and ventricular fibrillation
- Single-chamber ICD therapy where AF burden monitoring is clinically relevant
- Long-term remote follow-up via Medtronic CareLink Network
- Patient populations requiring MRI access under conditional scanning protocols
