Abstract
The material of the present study comprised one hundred
subjects [ Twenty with isolated rheumatic polyarthritis (group I),
twenty with rheumatic MS (group IT), twenty with rheumatic MR
(group Ill), twenety with rheumatic double mitral lesion (group IV)
and twenty as normal healthy control subjects ] to evaluate the
coexistance of MVP and rheumatic fever. All groups were studied
by echo. Doppler and the following results were obtained:-
* Significantly higher prevalence of unequivocal MVP in
rheumatic heart disease as a whole versus controls (P<O.05).
* Significantly higher prevalence of unequivocal MVP in isolated
rheumatic MR versus control (P<O.05)..
* Insignificant prevalence of unequivocal MVP in isolated
rheumatic MS, double mitral lesion as well as isolated
rheumatic polyarthritis (P>O.05).
* A positive correlation was found between MVP and the
following parameters:
1- Age (adult).
2- Female sex.
3- Systolic click.
4- Third heart sound.
5-MR.
6- End diastolic diameter.
The results were tabulated and statistically analysed.

* Rheumatic heart disease as a whole had a significantly higher
prevalence ofMVP than healthy controls.
* Patients with pure MR had the highest prevalence and those
with pure MS had the lowest prevalence, and this is well
appreciated by the underlying pathophysiology of valvular
lesion.
* Patients with isolated rheumatic polyarthritis showed
insignificant increase ofMVP prevalence than control subjects.
* A postinflamatory MVP may be the underlying etiology of pure
MR.
UMlTATION
* Small number of patients.
* Microscopic examination of spicemen from leaflets to define
pathology was not done as the study is a clinical one.
