Which finding is associated with mitral stenosis?

• A. Systolic murmur
• B. Atrial fibrillation
• C. Chest pain
• D. Dependent edema

Answer: (B)

Mitral stenosis is characterized by the narrowing of the mitral valve, which can lead to increased pressure in the left atrium and result in various complications. Atrial fibrillation is a common finding associated with this condition due to the enlargement of the left atrium that often occurs as a result of prolonged pressure overload. The enlarged atrium can lead to electrical disturbances, facilitating the development of atrial fibrillation. This arrhythmia can further exacerbate symptoms such as shortness of breath and fatigue, and can increase the risk of thromboembolic events. While other findings may occur in patients with mitral stenosis, such as a systolic murmur due to other related valvular issues or symptoms like chest pain or dependent edema, these are not as directly linked to the pathophysiological effects of mitral stenosis as atrial fibrillation is. The arrhythmia specifically stems from the changes in the atrial structure and function that occur in response to the stenosis. This connection highlights why atrial fibrillation is prominently featured as a key association of mitral stenosis.
