At which auscultation point is the mitral valve best heard?

The mitral valve is best heard at the apex of the heart, which is located in the left fifth intercostal space at the midclavicular line. This position brings the sound source closest to the chest wall during systole, making the mitral area’s normal sounds and any related murmurs most audible. Many clinicians listen with the patient in the left lateral decubitus position to further accentuate mitral sounds. For context, the aortic valve is best heard at the right second intercostal space near the sternal border, the pulmonic valve at the left second intercostal space, and the tricuspid valve along the left lower sternal border around the fourth intercostal space.
