A 52-year-old immigrant from Eastern Europe presents to the outpatient clinic complaining of dyspnea on exertion that has been increasing in severity over the past several weeks. She also describes nocturnal dyspnea and a cough that occasionally produces blood-tinged sputum. When the patient lies in the left lateral decubitus position and exhales fully, you hear a low-pitched, mid-diastolic murmur at the cardiac apex. Which of the following most likely underlies her condition and symptoms?
• A. Tuberculosis
• B. Infective endocarditis
C Uncontrolled hypertension
D. Atherosclerosis
E. Rheumatic fever
F. Dilated cardiomyopathy

This is an UWSA q. The answer is E. Can someone explain why B cannot induce MS?

The first thing that should pop into your head for mitral stenosis is Rheumatic fever (usually chronic forms). Acute rheumatic fever and endocarditis usually cause mitral regurgitation, I believe.

Chronic rheumatic fever = mitral stenosis.

Infective endocarditis generally presents with mitral regurgitation; the vegetations prevent the valve from staying closed and are generally not obstructive.
