[Coronarography in the study of myxoma. Apropos of a case diagnosed by this technic]
Insights
Coronary angiography can reveal intracardiac tumors like myxoma, even when initial tests are normal. This imaging technique is crucial for diagnosing myxoma and its complications when other methods are insufficient.
Area of Science:
- Cardiology
- Diagnostic Imaging
- Oncology
Background:
- Myxomas are the most common primary cardiac tumors, often presenting with nonspecific symptoms.
- Differentiating myxoma from myocardial infarction can be challenging based on initial clinical presentation.
Observation:
- A 59-year-old woman presented with symptoms suggestive of myocardial infarction, but coronary angiography revealed abnormal vascularity mimicking an intracardiac tumor.
- Despite normal auscultation and echocardiography, selective coronary angiography demonstrated features like aneurysms and hypervascularization suggestive of myxoma.
Findings:
- Selective coronary angiography proved valuable in diagnosing cardiac myxoma, particularly in cases where echocardiography or standard angiocardiography were inconclusive.
- The study analyzed 24 literature cases, with 20 showing "tumoral vascularization" on angiography, highlighting its diagnostic utility.
Implications:
- Coronary angiography can aid in the diagnosis of cardiac myxomas by identifying characteristic vascular patterns.
- This technique is useful for detecting complications such as coronaritis or embolic events associated with cardiac tumors.
- In challenging cases, coronary angiography offers a complementary diagnostic approach when traditional cardiac imaging modalities are deficient.
Abstract:
In a 59 years old woman presenting a rudimentary picture of myocardial infarction, ventriculograms confirm a limited necrosis and coronarography shows an abnormal vascular image, evoking an intracardiac tumor, while the arteries are free of atherosclerosis or thrombosis on angiography. Although auscultation and echography are normal, the diagnosis of myxoma will be confirmed by angiocardiography, then by surgery and pathology. The advantage of selective coronary angiography in myxomas is considered with 24 cases from the literature having undergone this examination, including 20 cases, among which ours, which present an aspect of "tumoral vascularisation". The particularities of coronarography (aneurysms, embolic obstruction, origin and aspect of hypervascularisation) are analyzed. This technique appears very useful, not only to detect a complication of the tumor or an associated coronaritis, but also to help in the diagnosis of myxomas in cases where angiocardiography or mostly echocardiography are deficient.
