Diagnosis of left atrial thrombi in mitral valve disease by coronary arteriography
1Institute of Cardiology, University of Catania, Italy.
Insights
Coronary arteriography can help diagnose left atrial thrombosis in mitral valve disease patients. This imaging technique shows neovascularity and fistula formation, aiding diagnosis when other methods fail.
Area of Science:
- Cardiology
- Diagnostic Imaging
Background:
- Left atrial thrombosis is a complication in patients with mitral valve disease.
- Coronary arteriography has shown neovascularity and fistula formation associated with left atrial thrombosis.
Purpose of the Study:
- To evaluate the diagnostic validity of coronary arteriographic findings for left atrial thrombosis in mitral valve disease patients.
- To determine the sensitivity, specificity, and predictive value of these angiographic findings.
Main Methods:
- Retrospective analysis of 112 patients with mitral valve disease.
- Comparison of coronary arteriography findings with surgical findings.
- Calculation of diagnostic values: sensitivity, specificity, and positive predictive value.
Main Results:
- The study found a sensitivity of 70%, specificity of 85%, and positive predictive value of 72% for diagnosing atrial thrombi using coronary arteriography.
- Neovascularity and fistula formation were key arteriographic indicators.
Conclusions:
- Coronary arteriography findings are a useful complementary tool for diagnosing left atrial thrombosis in mitral valve disease.
- Identification of these angiographic signs can improve diagnostic accuracy, particularly in challenging cases or when echocardiography is inconclusive.
Abstract:
Arteriographic findings of neovascularity and fistula formation between coronary arteries and left atrium have occasionally been described in association with left atrial thrombosis in patients with mitral valve disease. The validity of these coronary arteriographic findings in diagnosis of atrial thrombi has been evaluated in 112 patients with mitral valve disease. Comparison was made with surgery. The study furnished these diagnostic values: sensitivity 70%, specificity 85%, positive predictive value 72%. Even if this angiographic finding is complementary in diagnosis of atrial thrombosis, its identification during coronary arteriography in patients with mitral valve disease is useful. Its detection could improve diagnostic prediction of thrombosis, especially in patients without previous embolic events or where echocardiography failed to reveal thrombi.
