Which area is best heard for tricuspid valve pathology?

The area best for hearing tricuspid valve pathology is the left lower sternal border, around the 4th intercostal space. This location lies directly over the right ventricle and tricuspid annulus, so murmurs from tricuspid regurgitation or stenosis transmit most clearly here. In contrast, the apex is the mitral area (mitral valve), the right second intercostal space is the aortic valve area, and Erb’s point is a general listening site where many murmurs can be heard but isn’t specific to the tricuspid valve. Therefore, the left lower sternal border is the best spot to assess tricuspid valve pathology.
