PURPOSE OF REVIEW: To examine the evolving landscape of cardiac surgery, focusing on the increasing complexity of patients and the role of mechanical circulatory support (MCS) in managing perioperative low cardiac output syndrome (P-LCOS).
RECENT FINDINGS: P-LCOS is a significant predictor of mortality in cardiac surgery patients. Preoperative risk factors, such as cardiogenic shock and elevated lactate levels, can help identify those at higher risk. Proactive use of MCS, rather than reactive implementation after P-LCOS develops, may lead to improved outcomes by preventing severe organ hypoperfusion. The emerging concept of "protected cardiac surgery" emphasizes early identification of these high-risk patients and planned MCS utilization. Additionally, specific MCS strategies are being developed and refined for various cardiac conditions, including AMI-CS, valvular surgeries, and pulmonary thromboendarterectomy.
SUMMARY: This paper explores the shifting demographics and complexities in cardiac surgery patients. It emphasizes the importance of proactive, multidisciplinary approaches to identify high-risk patients and implement early MCS to prevent P-LCOS and improve outcomes. The concept of protected cardiac surgery, involving planned MCS use and shared decision-making, is highlighted. The paper also discusses MCS strategies tailored to specific cardiac procedures and the ethical considerations surrounding MCS implementation.
