Insights
A rare case of perioperative myocardial infarction occurred due to atheromatous emboli during coronary artery bypass surgery. Early diagnosis and treatment are crucial for preserving heart muscle and minimizing damage.
Area of Science:
- Cardiology
- Cardiac Surgery
- Vascular Surgery
Background:
- Coronary artery bypass surgery (CABG) is a common procedure for treating coronary artery disease.
- Complications can arise, including myocardial infarction (MI), which can be challenging to diagnose perioperatively.
- Atheromatous embolization is a potential, though infrequent, cause of perioperative MI during CABG.
Abstract:
We presented a female patient who had complicated perioperative myocardial infarction resulting from intraoperative embolization with atheromatous debris during coronary artery bypass surgery. On separation from cardiopulmonary bypass, ventricular function was poor and she suffered from severe low cardiac output syndrome postoperatively. The intraoperative electrocardiographic monitoring showed conduction abnormalities, elevation of the ST-T segments and new Q waves. Though it is difficult to diagnosis the onset of perioperative myocardial infarction early, adequate treatment is necessary to preserve ischemic myocardium and to reduce the size of myocardial necrosis.
