Summary
Selective antegrade coronary artery perfusion for myocardial preservation during cardiac surgery can lead to left coronary artery dissection. This complication resulted in myocardial infarction and fatal heart failure in a patient with severe valve disease.
Area of Science:
- Cardiovascular Surgery
- Cardiac Anesthesia
- Cardiopulmonary Bypass
Background:
- Selective antegrade coronary artery perfusion is a standard technique for myocardial preservation during complex cardiac surgeries.
- The patient presented with severe aortic valve stenosis and insufficiency, alongside mitral and tricuspid valve insufficiency, necessitating extensive surgical intervention.
Observation:
- Cardioplegia was delivered via selective antegrade coronary artery blood perfusion.
- A critical complication arose during the procedure: dissection of the left coronary main stem.
Findings:
- The left coronary artery dissection led to acute myocardial infarction.
- The patient ultimately succumbed to heart failure secondary to the myocardial infarction.
Implications:
- This case highlights a rare but severe complication associated with selective antegrade coronary artery perfusion.
- Careful monitoring and prompt recognition of coronary artery dissection are crucial in patients undergoing cardiac surgery with this perfusion technique.
- Further research into preventative strategies and management protocols for coronary artery dissection during perfusion is warranted.
