Where is disease of the mitral valve best heard on auscultation?

Mitral valve disease is best heard at the apex because that location lies over the left ventricle where the mitral valve sits. The apex, typically in the left fifth intercostal space at the midclavicular line, brings the auscultatory window closest to the mitral orifice, so murmurs and abnormal heart sounds from mitral lesions are most prominent there. Listening in this spot, especially with the patient in the left lateral decubitus position, enhances the ability to detect mitral murmurs. For example, mitral regurgitation tends to produce a holosystolic murmur most clearly heard at the apex, often radiating to the axilla. By contrast, other valve sounds are best heard in their respective areas: base regions for aortic/pulmonic, and left lower sternal border for tricuspid.
