mitral (bicuspid)‚ pulmonary‚ and aortic valves? For the tricuspid valves‚ the sounds of the heart are typically heard in the right sternal margin of the 5th intercostal space. For the Mitral (bicuspid) valve‚ sounds are heard over the heart apex‚ in the 5th intercostal space. This is in line with the middle of the clavicle. (Lutchman‚ 2016‚ PowerPoint). The pulmonary valve sounds are heard in the 2nd intercostal space at the left sternal margin. Lastly‚ the aortic valve sounds are heard in the 2nd
