Which type of stenosis is associated with a pinkish discoloration of the cheeks, known as "malar blush"?

• A. Aortic stenosis
• B. Mitral stenosis
• C. Pulmonary stenosis
• D. Tricuspid stenosis

Answer: (B)

Malar blush, characterized by a pinkish discoloration of the cheeks, is commonly associated with mitral stenosis. This phenomenon occurs due to increased pressure in the pulmonary circulation as a result of impaired blood flow from the left atrium to the left ventricle. When the mitral valve is stenotic, blood backs up into the pulmonary veins, leading to increased pulmonary venous pressure and congestion. The resultant pulmonary hypertension can cause dilation of the capillaries in the face, which manifests as the distinct blush. This blush is particularly notable in mitral stenosis due to the way it influences the hemodynamics of circulation. The other forms of stenosis do not typically produce the same hemodynamic changes that affect the distribution of blood flow and vascular reaction in the face in this manner. Thus, the association of malar blush with mitral stenosis is clinically significant and provides insight into the underlying circulatory dynamics of this condition.
