Coronary Artery Embolism and Myocardial Infarction, case report

Area of Science:

• Cardiology
• Vascular Medicine
• Interventional Cardiology

Background:

• Coronary embolism (CE) is an uncommon cause of non-atherosclerotic acute coronary syndrome (ACS).
• Atrial fibrillation (AF) is the most frequent underlying etiology for CE.
• Accurate diagnosis is crucial, often guided by the Shibata criteria.

Observation:

• A case report details a patient presenting with acute chest pain and newly diagnosed rapid ventricular response atrial fibrillation.
• Diagnostic imaging revealed a thrombotic lesion in the distal right coronary artery (RCA) consistent with embolism.
• Intravascular ultrasound (IVUS) confirmed the absence of atherosclerotic plaque, dissection, or residual thrombus after intervention.

Findings:

• Successful mechanical thromboaspiration was performed to treat the coronary embolism.
• The case highlights the importance of considering CE in patients with ACS and risk factors like AF.
• The study underscores that CE is likely underdiagnosed and associated with poorer patient outcomes.

Implications:

• This case emphasizes the need for heightened clinical suspicion for CE in ACS presentations, particularly with AF.
• Adherence to diagnostic criteria like Shibata is vital for timely and accurate diagnosis.
• Effective management strategies, including percutaneous intervention and anticoagulation, are critical for improving patient prognosis in CE.
