Where is disease of the tricuspid valve best heard?

Tricuspid valve murmurs are best heard along the left lower sternal border, at roughly the 4th left intercostal space near the sternum. This area coincides with the anatomical location of the tricuspid valve, which sits between the right atrium and right ventricle along the lower left side of the chest. The other sites correspond to other valves: the apex is the mitral area, Erb’s point is a general listening spot for many murmurs, and the right second intercostal space is the aortic valve area. Murmurs from the right side of the heart, including the tricuspid valve, often become more noticeable with inspiration, but the key location is the left lower sternal border.
