Insights
A patient experienced an intraoperative myocardial infarction due to injury of the left circumflex coronary artery. Coronary circulation compromise from nonintrinsic pathology can significantly increase patient morbidity.
Area of Science:
- Cardiology
- Cardiac Surgery
- Interventional Cardiology
Background:
- Coronary artery anatomy is critical for surgical planning.
- Accessory pathways can influence cardiac surgical risks.
Observation:
- A patient sustained an acute myocardial infarction (AMI) during surgery.
- The injury involved the distal portion of a dominant left circumflex coronary artery located in the atrioventricular groove.
Findings:
- Damage to the coronary artery during surgery led to AMI.
- Nonintrinsic pathology compromising coronary circulation is a significant risk factor.
Implications:
- Careful attention to coronary anatomy is essential during cardiac procedures.
- Understanding the relationship between accessory pathways and coronary circulation can prevent complications.
Abstract:
We report a patient who suffered an intraoperative AMI from injury to the distal portion of a dominant left circumflex coronary artery in the atrioventricular groove. Depending upon coronary anatomy and location of accessory pathways, compromise of coronary circulation by nonintrinsic pathology can be a major cause of morbidity.
