Acute Myocardial Infarction Due to Myocardial Bridge Treated With Surgery: a Case Report

Area of Science:

• Cardiology
• Congenital Heart Anomalies
• Vascular Surgery

Background:

• Myocardial bridging is a congenital anomaly where a segment of an epicardial coronary artery tunnels through the heart muscle (myocardium).
• This condition is associated with various ischemic heart diseases, including myocardial infarction.
• The anatomical variation can compromise coronary blood flow, particularly during systole.

Approach:

• This report details a clinical case of myocardial bridging complicated by acute anterior myocardial infarction.
• A comprehensive review of existing literature on myocardial bridging and its complications was conducted.
• The case involved a patient who underwent percutaneous intervention, which proved unsuccessful.

Key Points:

• The patient presented with acute anterior myocardial infarction secondary to myocardial bridging.
• Initial percutaneous coronary intervention (PCI) was unsuccessful in resolving the ischemia.
• Surgical management with coronary artery bypass grafting (CABG) was ultimately successful.

Conclusions:

• Myocardial bridging is a significant cause of myocardial infarction, especially in younger individuals.
• While PCI may be attempted, surgical revascularization is a viable and effective treatment option for complex cases.
• Early recognition and appropriate management are crucial for patients with symptomatic myocardial bridging.
