mechanical circulatory support
Also written as: MCS — mechanical circulatory support
Devices that assist or replace cardiac function, including ventricular assist devices, ECMO, and intra-aortic balloon pumps.
Full Definition
A broad category of mechanical devices designed to support or replace the pumping function of the failing heart in patients with severe cardiac dysfunction. These devices range from temporary support systems like intra-aortic balloon pumps and extracorporeal membrane oxygenation (ECMO) to long-term or permanent solutions such as ventricular assist devices (VADs) and total artificial hearts. Mechanical circulatory support is used in various clinical scenarios including cardiogenic shock, bridge to transplantation, bridge to recovery, and destination therapy for end-stage heart failure. The selection of appropriate device depends on the degree of cardiac dysfunction, expected duration of support, patient anatomy, and overall clinical goals. In cardiac surgery, these devices may be used perioperatively for patients unable to wean from cardiopulmonary bypass or postoperatively for hemodynamic support during recovery.
Usage
Usage note: Specify the type and purpose of mechanical support (temporary vs. permanent, bridge vs. destination therapy).
In Context
- "Mechanical circulatory support was initiated with ECMO due to inability to wean from cardiopulmonary bypass." — postoperative note
- "The patient was evaluated for long-term mechanical circulatory support as a bridge to transplantation." — heart failure consultation
