Is the presence of left atrial thrombus common in patients diagnosed with mitral stenosis?

The presence of left atrial thrombus is indeed common in patients diagnosed with mitral stenosis, particularly in the left atrial appendage. Mitral stenosis often leads to increased pressure and volume in the left atrium due to the obstruction of blood flow from the left atrium to the left ventricle. This results in left atrial dilation and turbulent blood flow, creating an environment conducive to thrombus formation.

The left atrial appendage is a site known for thrombus development in such patients, primarily due to reduced blood flow and stasis. It's essential for healthcare professionals to be aware of this increased risk because the presence of a thrombus can lead to serious complications, such as systemic embolism and stroke.

In patients with mitral stenosis, the risk of thrombus formation correlates with the severity of the stenosis, but it is not limited to advanced stages or all patients uniformly. Instead, it is a notable concern, especially in those with significant left atrial enlargement and hemodynamic changes associated with the condition.
