Monitoring cardiac and ascending aortic procedures

Area of Science:

• Neurology
• Cardiovascular Surgery
• Neurophysiology

Background:

• Cardiac and aortic surgeries carry a significant risk of neurologic complications, particularly stroke.
• Stroke rates remain high at 1-5% for cardiac operations and 7-10% for aortic operations.
• Despite advancements in surgical techniques, neurologic complication rates persist.

Purpose of the Study:

• To provide an overview of cardiac and aortic arch procedures from a neurophysiologic perspective.
• To discuss the role of intra-operative neurophysiologic monitoring (IONM) in improving surgical outcomes.
• To highlight the utility of various monitoring modalities in identifying neurologic injury during surgery.

Main Methods:

• Review of neurophysiologic monitoring techniques relevant to cardiac and aortic surgeries.
• Analysis of the application of IONM in the context of specific surgical procedures.
• Discussion of different monitoring modalities and their effectiveness.

Main Results:

• IONM offers a potential strategy to mitigate the high risk of stroke associated with cardiac and aortic operations.
• Specific neurophysiologic monitoring modalities can detect intra-operative events indicative of potential neurologic injury.
• Understanding the neurophysiologic aspects of these surgeries is crucial for risk reduction.

Conclusions:

• Intra-operative neurophysiologic monitoring is a valuable tool for improving outcomes in cardiac and aortic surgery.
• IONM has the potential to decrease the incidence of neurologic complications, including stroke.
• The judicious use of IONM can enhance patient safety during complex cardiovascular procedures.
