[Intraoperative transesophageal echocardiography in diagnosing left atrial thrombosis in patients with mitral valve
Insights
Transesophageal echocardiography effectively detects left atrial thrombosis, especially in mitral stenosis patients. Spontaneous echo-contrasting indicates thrombosis risk with high accuracy.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Left atrial thrombosis is a significant complication in cardiosurgical patients, particularly those with mitral valve disease.
- Accurate intraoperative detection of thrombosis is crucial for patient management and surgical outcomes.
Purpose of the Study:
- To evaluate the utility of intraoperative transesophageal echocardiography (TEE) in diagnosing left atrial thrombosis.
- To assess the significance of spontaneous echo-contrasting as an indicator of thrombosis in mitral stenosis.
Main Methods:
- Intraoperative transesophageal echocardiography was performed on 63 patients undergoing cardiosurgery.
- Patients had various conditions including mitral stenosis, mitral incompetence, and combined valvular diseases.
- Findings such as left atrial thrombosis and spontaneous echo-contrasting were recorded and analyzed.
Main Results:
- Left atrial thrombosis was diagnosed in 13 patients.
- Spontaneous echo-contrasting was observed in 38 patients and was statistically associated with mitral stenosis complicated by thrombosis (p < 0.001).
- TEE visualized small thrombi (1.0-1.5 cm) with 100% specificity and 87% sensitivity.
Conclusions:
- Intraoperative TEE is a highly specific and sensitive method for detecting left atrial thrombosis.
- Spontaneous echo-contrasting is a valuable sign for identifying mitral stenosis patients at risk of left atrial thrombosis.
Abstract:
Intraoperative transesophageal echocardiography was conducted in 63 patients with various cardiosurgical pathology (mitral stenosis--43, combined mitral valvular disease--3, mitral incompetence--10, combined mitral-aortal valvular disease--8). Thrombosis of the left atrium was diagnosed in 13 patients. Transesophageal echocardiography in 38 patients revealed spontaneous echo-contrasting of blood currents in the cavity of the left atrium. Statistical analysis showed this sign to be characteristic of mitral stenosis complicated by thrombosis of the left atrium (p < 0.001). Transesophageal echocardiography allows visualization of thrombi of small diameter (1.0-1.5 cm). Specificity of the method is 100%, sensitivity 87%.
