ABSTRACT

Background: Cardiogenic shock is a critical condition where the heart fails to pump blood effectively, lead- ing to high mortality rates. Mechanical circulatory support can temporarily reduce the heart’s workload while maintaining systemic perfusion. This paper in- troduces the Suction Pump Assist Device, an early mechanical support system patented in 1979.

Aim: To present the design, working principle, and clinical relevance of the Suction Pump Assist Device and compare it to the modern standard, Extracorpo- real Membrane Oxygenation (ECMO).

Method: The working principle of the suction pump assist device was analyzed and compared to ECMO, which has been the standard of care for cardiogenic shock since 2016.

Results: The Suction Pump Assist Device operates on a principle similar to VA-ECMO, where venous blood is oxygenated externally and returned to the arterial system, thereby reducing cardiac workload and ensur- ing systemic oxygenation. While ECMO has evolved significantly with technological advancements, the fundamental concept remains consistent.

Conclusion: The Suction Pump Assist Device repre- sents an early innovation in mechanical circulatory support for cardiogenic shock, sharing key principles with modern ECMO systems.
