Terminology used to describe MCS devices or indications for use
| Term . | Definition . | Device examples . |
|---|---|---|
| Description of device | ||
| Extracorporeal | Pump for device located outside of the body | ECMO, CPB, EXCOR |
| Intracorporeal | Pump for device located with the body | HeartMate 3, HVAD |
| Temporary | Device intended for limited duration of support (hours-days) | Impella 2.5, Impella CP, ECMO |
| Durable | Device with capability of support for months-years | HeartMate 3, HVAD |
| Partial support | Device provides less flow than complete cardiac output | Impella 2.5 |
| Full support | Device provides complete cardiac output | ECMO, EXCOR, HeartMate 3, HVAD |
| Dischargeable | Device does not require hospitalization for continued support | HeartMate 3, HVAD |
| Type of flow | ||
| Pulsatile | Device with flexible membranes that creates intermittent flow and a pulse | Total artificial heart, EXCOR |
| Nonpulsatile/continuous flow | Device that provides constant blood flow | HeartMate 3, HVAD |
| Axial | Device with inlet and outflow in the same axis and flow produced by rotating impeller | HeartMate II, Jarvik 2000 |
| Centrifugal | Device with inlet perpendicular to outflow tracts. Flow produced by centrifugal force. | HeartMate 3, HVAD |
| Indication for MCS use | ||
| Bridge to transplant | Device implanted to support patient until a heart transplant | HeartMate II, HVAD |
| Bridge to candidacy | Device implanted to support patient until can determine whether eligible for a heart transplant | HeartMate II, HVAD |
| Bridge to recovery | Device implanted until myocardial recovery from injury | HeartMate II, HVAD |
| Destination therapy | Device implanted to support patients who are ineligible for heart transplant | HeartMate II, HVAD |
| Short term | New term to describe device implanted with intention for months-years of support (replaces bridge to transplant or recovery) | HeartMate 3 |
| Long term | New term to describe device implanted with the intention for years of support (replaces destination therapy) | HeartMate II, HVAD |
