A 60-year-old woman experienced acute myocardial infarction due to a right coronary artery thrombus complicated by coronary aneurysms. Multi-detector row computed tomography (MDCT) identified the cause, leading to warfarin anticoagulant therapy.
Area of Science:
- Cardiology
- Radiology
Background:
- Acute myocardial infarction (AMI) can arise from complex coronary artery pathologies.
- Coronary aneurysms present a risk factor for thrombus formation and subsequent ischemic events.
Observation:
- A 60-year-old female patient presented with symptoms suggestive of AMI.
- Multi-detector row computed tomography (MDCT) revealed a thrombus within the right coronary artery, associated with coronary aneurysms.
Findings:
- MDCT imaging was instrumental in accurately diagnosing the coexisting coronary aneurysms and thrombus.
- The identified thrombus within the aneurysmal right coronary artery was deemed the causative factor for the patient's AMI.
Implications:
- This case highlights the diagnostic utility of MDCT in complex coronary artery disease.
- Prompt identification of thrombus in coronary aneurysms is crucial for initiating appropriate anticoagulant therapy, such as warfarin, to prevent recurrent ischemic events.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
