Heart click

With newer, non-invasive imaging techniques, the origin of other, so-called adventitial sounds or heart clicks has been appreciated. These are short, high-pitched sounds.[citation needed]
- The mitral valve in cases of mitral stenosis may open with an opening snap[1][2] on the beginning of diastole.
- Patients with mitral valve prolapse may have a mid-systolic click along with a murmur, referred to as apical late systolic murmur.[3] Early systolic clicks may also be present in some patients.[4]
- Aortic and pulmonary stenosis may cause an ejection click[5] immediately after S1.
