Life Prolongation

This summary will provide you information on the potential benefits and risks you can expect from receiving an LVAD. It is designed to be reviewed with the input of your healthcare team and alongside the “Deciding Together” decision, which you can find at

The survival estimates for living without an LVAD are generated differently by different healthcare teams, and if you are on IV medications, your prolongation may be lower. The numbers you see represent your healthcare team’s best guess at your survival at 1 and 2 years. The personalized estimates are generated by the HM3RS calculator, which compares your clinical profile against others like you who have received an LVAD. For more, go to

Possible Challenges

LVAD also comes with some risks and potential complications. The material below provides average risk estimates of certain complications and difficulties involved in life post-VAD.
The Heart Mate 3 Risk Score (HM3RS) seen to the right classifies patients as being at lower risk, average risk, or higher risk when compared to other patient. Higher risk does not necessarily mean that you should not get the LVAD. Consider overall survival benefits as well.

Your Heart Mate 3 Risk Score

Your specific Heart Mate 3 Risk Score with LVAD is 0.00, placing you at average risk.
You are here: 0.00
0.00 – 2.40
2.41 – 2.96
2.97 – 4.60+
