Postcardiotomy cardiogenic shock is a life-threatening situation that may develop after a surgical procedure on the heart (e.g. coronary artery bypass grafting [CABG], open heart surgery on a heart valve). The heart may not resume proper function and blood pressure becomes very low, signifying the heart’s inability to adequately pump oxygenated blood to vital organs.
When postcardiotomy cardiogenic shock occurs, the patient may not be healthy enough to be weaned from a cardiopulmonary bypass (CPB) machine or another type of heart assist device, which was intended to support the patient’s heart only while the surgical procedure was taking place.
