Which area corresponds to the Mitral (apical) Area?

• A. Mitral (apical) Area
• B. Aortic Valve Area
• C. Pulmonic Valve Area
• D. Tricuspid Area

Answer: (A)

Listening for heart sounds follows the heart’s anatomy: the mitral valve is best heard at the apex. The apex sits at the left fifth intercostal space in the midclavicular line, where the maximal impulse (apical impulse) is felt. Because the mitral valve is closest to the chest wall at this spot, its sounds—especially S1—are most prominent there. In practice, you hear mitral valve sounds best with the patient in the left lateral decubitus position and at the end of expiration. The apical area thus corresponds to the mitral valve location. For context, other valve areas sit at different chest locations—for example, the aortic area is at the right second intercostal space, the pulmonic area at the left second intercostal space, and the tricuspid area along the left lower sternal border.
