[Cold agglutinins in a cardiosurgical patient: a successfully operated case]

Area of Science:

• Cardiovascular Surgery
• Cardiac Anesthesia
• Cardiomyopathy

Background:

• Cold autoagglutinins pose a significant risk during cardiac surgery requiring cardiopulmonary bypass and hypothermic cardioplegia.
• Traditional cold cardioplegia can trigger severe hemolytic reactions in patients with cold autoagglutinins.
• Myocardial protection strategies must be adapted to mitigate risks associated with specific patient conditions.

Observation:

• A novel technique was employed for myocardial protection during cardiac surgery in a patient with cold autoagglutinins.
• The procedure involved perfusing the coronary arteries with normothermic (37°C) saline solution to displace blood before introducing cold (4°C) cardioplegic solution.
• The surgery was performed under normothermic conditions to further minimize the risk of autoagglutinin activation.

Findings:

• The described technique successfully provided myocardial protection without inducing adverse reactions related to cold autoagglutinins.
• The patient underwent an uneventful operation for right ventricular-outflow tract stenosis.
• This approach demonstrates the feasibility of using cold cardioplegia in patients with cold autoagglutinins when modified appropriately.

Implications:

• This technique offers a safer alternative for myocardial protection in patients with cold autoagglutinins, expanding surgical options.
• It highlights the importance of tailored cardioplegia strategies based on patient-specific conditions.
• Further research may validate and refine this method for broader clinical application in complex cardiac surgeries.
