Heart click

With the advent of 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.

• The atrioventricular valves of patients with 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]
• Aortic and pulmonary stenosis may cause an ejection click^[4] immediately after S₁.
