Q: Why auscultation of heart is an important component in the evaluation of hemoptysis?
Answer: To rule out mitral stenosis or mitral regurgitation as a cause of hemoptysis
Though not high on the list, but the presence of murmur of mitral valve should raise the possibility of the cardiac source of hemoptysis. This can be supplemented with echocardiography and evaluation of upper lobes of lungs via radiological workup.
