[2 cases of coronary embolism. Angiographic diagnosis and anatomopathological confirmation]
Insights
Coronary embolism, a rare cause of heart attack, can be diagnosed using angiography. This diagnostic method relies on identifying blockages and ruling out other coronary artery issues.
Area of Science:
- Cardiology
- Radiology
- Pathology
Background:
- Coronary embolism is an infrequent cause of myocardial infarction.
- A retrospective analysis of 61 cases over 18 years was conducted.
Observation:
- Two specific cases of coronary embolism were selected for detailed analysis.
- Coronary angiography was performed on these cases, correlating with autopsy findings.
Findings:
- Angiography revealed characteristic signs of obstruction due to embolism.
- Key diagnostic indicators include normal coronary circulation and absence of collateral vessels, suggesting a diagnosis of exclusion.
Implications:
- This study refines the understanding of radiological features for diagnosing coronary embolism.
- Accurate angiographic diagnosis aids in identifying the causes and clinical manifestations of coronary embolism.
Abstract:
The authors report two cases selected from a series of 61 cases of coronary embolism observed over an 18 year period at the Cardiovascular Hospital (Lyon) out of 4,860 autopsies of adult patients who died of cardiovascular causes. These two cases underwent coronary angiography, the results of which correlated with the autopsy findings. The authors review the causes and clinical manifestations of coronary embolism and compare their results with previously reported data, to establish the radiological features of coronary embolism. They notice the regular appearance of obstruction due to embolism and underline the importance of the associated negative signs (normality of the rest of the coronary circulation, absence of collateral vessels...) which makes the angiographic diagnosis one of elimination.
