Early diastolic murmur along right sternal border – Medicine MCQ – CVS – Answer
Early diastolic murmur well heard along the right sternal border – Correct answer: c) Aortic regurgitation with dilated aorta.
Pulmonary regurgitation produces early diastolic murmur in the pulmonary area and along left sternal border. Mitral stenosis produces mid diastolic murmur in mitral area and tricuspid stenosis produces mid diastolic murmur in tricuspid area.
Aortic regurgitation produces early diastolic murmur heard in aortic area and secondary aortic area along the left sternal border (Erb’s area). But if the aorta is dilated as in annuloaortic ectasia, early diastolic murmur will be well heard along the left sternal border as the dilated ascending aorta reaches that region. In earlier years syphilitic aortitis also could be seen with dilated ascending aorta and aortic regurgitation.
