About

The study aims to investigate the safety and efficacy of the Synchronized Cardiac Support treatment wit the icor kit and the Xenios console with modified sensor box ECG and Software Version 3.2.4

Full description

The current study hypothesizes that The SCS treatment with the icor kit provides sufficient support for cardiocirculatory function as indicated by a significant lactate reduction 24 hours on SCS treatment versus before treatment start.

Patients with cardiogenic shock, requiring a venoarterial extracorporeal membrane oxygenation (VA ECMO) for cardiocirculatory stabilization will be treated with Synchronized Cardiac Support.

Synchronized Cardiac Support describes an electrocardiogram (ECG)- triggered pulsatile VA-ECMO based on R-wave detection. During diastole the pump speed and thus the flow is increased and during systole the pump flow is been set on a relative minimum. This provides a mechanical circulatory support pulse with oxygenated blood during diastole.

The Synchronized Cardiac Support Treatment is used in a standard VA ECMO configuration by two femoral single vessel cannulas. Patients following cardiac resuscitation will undergo targeted temperature management 32- 36°C according to guideline.

The Duration of Treatment can be up to 14 days.

4. Cardiogenic shock is defined as:

   1. Systolic blood pressure < 90 mmHg for at least 30 min
   2. Inotropes and/or vasopressors are needed to maintain systolic blood pressure > 90 mmHg
   3. Clinical signs of heart insufficiency with pulmonary congestion

6. No flow time > 5 min
7. Mechanical causes for cardiogenic shock (ventricular septal defect of papillary muscle rupture)
8. Non-cardiogenic causes of shock (bradycardia, sepsis, hypovolemia, etc.)
9. Fever (Body temperature > 38.0 °C) or other evidence of sepsis
10. Onset of cardiogenic shock > 6 h before enrolment
11. Lactate > 16 mmol/L
12. Severe peripheral arterial occlusive disease precluding insertion of femoral arterial or venous catheters
