A 76-year-old man with a history of diabetes mellitus and hypertension presents with progressively worsening exertional dyspnea, limiting his ambulation to approximately 10 meters. On physical examination, a forceful apex beat is noted along with a harsh crescendo-decrescendo ejection systolic murmur, loudest at the right upper sternal border and radiating to the carotid arteries. What is the most likely diagnosis?
- AMitral stenosis
- BAortic stenosisCorrect answer
- CPulmonary stenosis
- DAortic regurgitation
Explanation
The exertional dyspnea, forceful apex beat, and characteristic crescendo-decrescendo ejection systolic murmur radiating to the carotids strongly point to aortic stenosis — common in elderly patients with cardiovascular risk factors, as calcification of the aortic valve progresses.
