Genetics of coagulation: considerations for cardiac surgery

Intracardiac Thrombosis and Acute Right Ventricular Failure Following Complex Reoperative Cardiac Surgery With Aprotinin and Deep Hypothermic Circulatory Arrest

Although coagulopathy and bleeding are common in the setting of cardiac surgery, a growing number of case reports in the literature suggest that hypercoagulability may also result in significant morbidity and mortality. We present a case of apparent hypercoagulability with formation of thrombus in the cardiac chambers following reoperative cardiac surgery using cardiopulmonary bypass, aprotinin, and deep hypothermic arrest. A review of those hypercoagulable disorders with reported impact on cardiac surgery and a discussion follow the case presentation.

Management of the clotting system: a European perspective

PURPOSE OF REVIEW

Coagulation management remains a challenge for anesthesiologists involved in cardiovascular surgery as the population undergoing surgery becomes older and presents with more comorbidities. These patients are frequently treated with one or more agents that directly affect coagulation. This review will discuss what is known and the treatments available to manage coagulation in the perioperative setting of cardiac surgery.

RECENT FINDINGS

New antithrombotics will be discussed as well as their proposed substitution in the preoperative period. The review will also describe the different products available in Europe for the treatment of bleeding and coagulopathy. Finally, the use of new monitoring devices will be discussed.

SUMMARY

The introduction of new drugs with different mechanisms of action adds to the complexity of coagulation management during cardiovascular surgery. Monitoring needs to be developed and improved, especially for evaluating platelet function.
