ICD-10-AM Code: I34.1
This is a disorder of the mitral valve of the heart, where the valve prolapses into the atrium during ventricular contraction. It may result in mitral regurgitation. If so it is usually mild or trivial and more rarely may become severe.
Confirming the diagnosis
Echocardiography is required, with specific criteria used to establish the diagnosis.
The relevant medical specialist is a cardiologist.
Additional diagnoses covered by SOP
- Barlow syndrome/disease
- Floppy mitral valve (syndrome)
- Mitral regurgitation in the presence of mitral valve prolapse, but excluding other causes.
Conditions excluded from SOP
- Other heart valve disorders not affecting the mitral valve
- Mitral stenosis#
- Mitral valve disease in Marfan syndrome*
- Mitral regurgitation in the absence of prolapse
- Rheumatic heart disease affecting the mitral valve*
- Flail mitral valve leaflets#
* another SOP applies
# non-SOP condition
The condition does not have any reliable, specific symptoms. The first clinical evidence is likely to be a heart murmur heard on ascultation (via a stethescope).
The only SOP worsening factor is for inability to obtain appropriate clinical management. Mild disease requires no treatment beyond observation. Severe mitral regurgitation may require surgery.
