Mid-Systolic Click

Join our Auscultation-Essentials plan
A mid systolic click can be heard at the mitral valve area. The first and second heart sounds are normal. The second heart sound is unsplit and no murmur is present so that you can concentrate on the systolic click. Mid systolic click are often followed by a late systolic murmur of mitral valve leaflet prolapse. On the anatomy video, found below, you can see that the mitral valve posterior leaflet prolapses. The mid systolic click is produced by the sudden prolapse of this leaflet.
