Serial echocardiographic abnormalities in nonbacterial thrombotic endocarditis of the mitral valve
Insights
Nonbacterial thrombotic endocarditis (NBTE) can cause repeated embolic episodes. Echocardiography revealed mitral valve masses and restricted motion, confirmed surgically as sterile fibrin thrombi.
Area of Science:
- Cardiology
- Cardiac Surgery
- Pathology
Background:
- Nonbacterial thrombotic endocarditis (NBTE) is a rare condition characterized by sterile vegetations on heart valves.
- NBTE can lead to significant embolic complications, posing diagnostic and therapeutic challenges.
Observation:
- A patient with NBTE presented with recurrent embolic events.
- Serial echocardiography demonstrated evolving abnormalities, including a mass on the anterior mitral leaflet and restricted valve motion.
- Cineangiography confirmed a large filling defect suggestive of a mitral valve vegetation.
Findings:
- Surgical exploration revealed a large vegetation on the mitral valve.
- Pathologic examination of the surgical specimen identified a sterile, partially organized fibrin thrombus, consistent with NBTE.
- Echocardiographic findings correlated with clinical presentation and surgical pathology.
Implications:
- This case highlights the utility of serial echocardiography in diagnosing and monitoring NBTE.
- Understanding the echocardiographic manifestations of NBTE is crucial for timely surgical intervention and prevention of embolic events.
- The findings underscore the importance of considering NBTE in patients with unexplained embolic phenomena and cardiac masses.
Abstract:
This report describes the clinical course and serial echocardiographic abnormalities in a patient with nonbacterial thrombotic endocarditis and repeated embolic episodes. Serial echocardiograms revealed a mass of abnormal echoes on the anterior mitral leaflet and progressive restriction of mitral valvular motion. Cineangiographic studies demonstrated a large filling defect in the area of the mitral valve. Surgical intervention confirmed the presence of a large vegetation on the mitral valve. The surgical specimen consisted of a sterile, partially organized fibrin thrombus. The echocardiographic abnormalities are described and discussed in relation to the clinical and pathologic findings.
