Abstract :

[en] Postoperative Low Cardiac Output Syndrome (LCOS) is a postoperative myocardial dysfunction that compromises tissue oxygen delivery. Today, it still complicates approximately 10% of adult cardiac surgeries. It is associated with increased morbidity and mortality, as well as a significant rise in healthcare costs and the use of hospital resources. The pathophysiology of this syndrome is complex and involves pre-existing factors such as prior myocardial dysfunction, intraoperative factors such as myocardial injury resulting from ischemia-reperfusion related to aortic clamping, as well as postoperative elements. A prompt diagnosis of this syndrome is essential. Indeed, it is crucial to identify and treat reversible causes, but also to restore adequate cardiac output to prevent organ failure. Management is primarily based on the use of inotropic agents. Mechanical circulatory support devices may be required in cases of post cardiotomy shock that is not adequately managed with pharmacological therapies.
