Surface Projection of Heart Valves
The heart valves ensure proper directional blood flow and can be mapped on the chest wall based on anatomical landmarks.
Aortic Valve
Located at the second right intercostal space at the sternal border.
Pulmonary Valve
Situated at the second left intercostal space at the sternal border.
Tricuspid Valve
Projected onto the right side of the sternum near the fifth intercostal space.
Mitral Valve
Found at the left fifth intercostal space, medial to the midclavicular line.
Clinical Significance
Auscultation of heart sounds relies on these surface projections to assess valve function and detect murmurs.
