Why the study?
What is the prevalence and what are the risk factors for left atrial thrombi detected by echocardiography in patients with mitral stenosis?
What is the prevalence and what are the risk factors for left atrial thrombi detected by echocardiography in patients with mitral stenosis?
Atrial fibrillation and left atrial enlargement are key risk factors for the development of left atrial thrombi in patients with mitral stenosis.
May guide LA thrombus screening in mitral stenosis; leaves open prospective validation of risk stratification.
Sixty-nine patients with predominant mitral stenosis were examined by echocardiographic means to detect the presence of left atrial thrombi. Forty-nine of these patients were in sinus rhythm and twenty in atrial fibrillation. Four percent of patients in the sinus rhythm group and 45% of those in the atrial fibrillation group had left atrial thrombi. The two risk factors identified for left atrial thrombi in mitral stenosis were atrial fibrillation and left atrial enlargement.
