Compare Remote Patient Management and Standard Care in CRT-D and ICD-patients to Assess the Effect on Heart Failure (ConnectOptiVol)

June 30, 2025 updated by: Medtronic Cardiac Rhythm and Heart Failure

Clinical Evaluation to Assess the Effect of the Combination of a Pre-Defined Management Pathway to Reduce Fluid Overload in Cardiac Decompensation With Carelink Remote Management, Connexus Remote Telemetry and the OptiVol Early Warning System on Health Care Utilization

This pilot study is to prospectively evaluate the benefit of clinicians being able to access ICD device information in a timelier manner and treat fluid overload with a pre-defined pattern using the Medtronic OptiVol, Medtronic CareAlerts and Medtronic CareLink in Conexus-enabled devices (remote arm) as compared to the same devices without Medtronic OptiVol, Medtronic CareAlerts and Medtronic CareLink available to the treating physician (standard arm).
