Clinician tools for HVAD™ patient management
Patient planning tool
This tool is intended to help clinicians develop personalized management plans for HVAD™ patients. Content in this tool is based on recommendations in previously published Field Corrective Actions (FCAs) and is not intended to be prescriptive. As always, patient care decisions should be made by practitioners on a case-by-case basis, based on their clinical judgment.
This tool will be updated as needed; please bookmark and refer back to this page regularly.
Use this Planning Worksheet to develop a case-by-case assessment for your patients.
For complete information regarding patient management recommendations, please reference the mechanical circulatory support HVAD product advisories via the Medtronic website.
For additional HVAD™ patient management resources, please consult the Medtronic manual library, and contact your local Medtronic field representative.

Cumulative probability of experiencing a pump stop resulting in failure or delay to restart (by 3 years) [JAN 2026] |
||
|---|---|---|
| High risk subgroups | 1 | 3.1% |
| 2 | 31.3% | |
| 3 | 3.8% | |
| General HVAD population | 0.4% | |
During medium priority alarms, the pump is still working.
[Controller Fault] alarms have several potential causes (e.g., internal battery end-of-life, component malfunctions) which may be identified using logfile analysis.
The decision to change the controller or what other action is needed will be based on logfile analysis and patient‘s clinical condition.

Permanently silencing the [Controller Fault] alarm due to a low internal battery
One purpose of the [Controller Fault] alarm is to alert the user that the internal battery is nearing end-of-life.
When the internal battery completely depletes, the [No Power] alarm will not sound during a loss of power (e.g., double power disconnect).
Using the HeartWare monitor, the low internal battery [Controller Fault] alarm may be permanently silenced once the alarm is activated.
All other alarms will remain active as long as the controller has external power.
Re-silencing a [Controller Fault] alarm due to internal battery end-of-life may be required:
• Following a double power disconnect;
• If the internal battery charge rebounds and then later depletes to the low internal battery threshold.

Consideration for performing these actions, including a controller exchange, should be made on a case-by-case basis taking into account the patient’s individual risk. At all times, it is the professional responsibility of the practitioner to exercise independent clinical judgment in a particular situation.

A [VAD Stopped] Alarm will occur when a controller has been powered on, but a driveline has not yet been connected.
Disable “VAD Stop” Alarm Feature:
• Designed to silence the high priority [VAD Stopped] alarm during the programming of an HVAD controller.
• Disables the HVAD pump from starting automatically when a driveline is connected to the controller.

Instructions for evaluating the driveline cover
While immobilizing the controller, push the DL toward the controller and pull the DL cover back from the flange with a side-to-side wiggle motion.
DO NOT pull the driveline cover with excessive force or use a twisting motion as this may damage the DL connector or dislodge the DL connection.

Advise patients that, whenever possible, controller exchanges should be performed under clinical supervision, as it will likely be difficult to pull back the driveline cover to access the driveline connector.
Leave DL cover in place. Medtronic does not recommend clinicians tamper with or cut off the cover or remove it.

Explant of the HVAD pump
Routine prophylactic explant of the HVAD pump is not recommended as risks associated with explanation may outweigh potential benefits of continued HVAD therapy.1
Physicians should make the decision regarding explant/exchange of the HVAD pump on a case-by-case basis, considering the patient‘s clinical condition and surgical risk.
