Clinically the common causes of valvular
heart lesions are congenital, rheumatic fever and
alcification. There are conflicting reports regarding
their prevalence. So to study the prevalence and to see
the age and sex-wise distribution of various cardiac
valvular abnormalities a study was designed at Mayo
Hospital, Lahore. It was observed that the most common
problem was mitral valvular lesion presenting with
palpitations and the age group most affected was 21-40
years with female preponderance. It was suggested that
the young population (21-40 years) should get a regular
cardiac check up.
Key words: Mitral regurgitation (MR), tricuspid
regurgitation(TR), aortic regurgitation (AR), mitral
stenosis(MS)
Clinically the most common causes of valvular heart
diseases are congenital malformation, rheumatic fever
and calcification of the valves in elderly. Inequality
in the cusp size also plays an important role in the
pathogenesis of the disease1. Regarding
prevalence of valvular lesions there are conflicting
reports2,3. The patients present with
anxiety, atypical chest pain that is related to exertion
and syncope3.
| Aims
and objectives : |
-
To know relative distribution of valvular
heart disease and see the symptoms.
-
To know the age and sex wise distribution
of the disease.
-
To point out the important risk factors
which play an important role in the pathogenesis of the
disease.
-
To study the relationship of the disease
to other factors.
-
To find out the results of the study and
compare them with other research work.

Subject & methods : |
|
This was a retrospective study
carried out in the Department of Cardiology, Mayo
Hospital, Lahore over a period of two months. Fifty
two subjects were included in the study. We excluded
those patients from our study who were admitted,
suspecting them to be suffering from valvular
disease but later, the investigations failed to
confirm it.The study pattern was as follows:
Taking the case history of the patients, general
physical examination, which included the sign such
as breathlessness, syncope, palpitation etc.
Visible signs such as chorea, subcutaneous nodules,
fever, joint pain were also observed.The lab tests
included ESR measurement, Hb, ASO, urine etc., based
on the tests a provisional diagnosis was made which
the ECG, 2-D echo and colour doppler facilitation
later on confirmed.

Results : |
|
Out of 52 cases 36
were male and 16 females. The maximum cases were in
age group 21-40 years (20-30) in which males were
60% & females 40%.

The most common complaint was palpitations (86.5%)
followed by chest pain (83.4%) breathlessness (83%)
fever (56%), syncope (52%) and joint pain (24%).

(n=7, in 57% females & 43% males) and other diseases
diagnosed were aortic stenosis (n=4), aortic
regurgitation and tricuspid regurgitation.

Discussion |
|
The study conducted on the patients
suffering from valvular heart diseases in the Mayo
Hospital, lahore clearly points out the greater
frequency of the disease.
It is said that mitral valve prolapse is a
predominantly inherited condition4, which
is further supported by high prevalence of mitral
valve prolapses in patients of congenitally acquired
connective tissue disorders5. In an
echocardiographic study of 1734 new borns, not a
single case of mitral valve prolapse was found6.
Maximum number of our cases were in age group 21-40
years, which is in accordance with other studies in
which mean age was found to be 30 years. Mitral
valvular lesion is found to be more common in
females 57% as compound to males 43% similar result
are shown by Chengt To7. Our study showed
that in our patients, 46% had mitral stenosis, 35%
had mitral regurgitation, 10% had aortic
regurgitation while the rest had either a
combination of these or a multi-level obstruction.
When examined across different age groups, the
prevalence of the MR and TR, of more than mild
severity, increased with advancing age in both
sexes.
The most common presenting complaint in our study
was palpitations (86.5%) which is in accordance with
a study of Suhail N et al8. While in some
other studies the common presentation is panic
disorders and depression9. Coming to
socioeconomic aspect of the valvular disease, which
we came across in the course of our study, it has to
be said that the treatment of the disease is quite
costly. Most of the patients, who were already in
the advanced stage of the disease, were still denied
treatment because of their poor economic background.
Our observation was that a great deal of improvement
was required and was possible as well.

Conclusion : |
|
Our research concluded that;
Mitral stenosis is the most common valvular heart
disease observed in our study with mitral
regurgitation and aortic stenosis to follow.
The important factors contributing to it are either
congenitally malformed valves, rheumatic arthritis
or mechanical injury, calcification of valves due to
hypercholestrolism etc.
At presentation, the most commonly seen signs and
symptoms were anxiety, dyspnoea and palpitation.The
most affected age group was 21-40 years.
|
|
Suggestions : |
|
There was a low rate of success in
the treatment of valvular disease because of the
severity of the disease at presentation. Early
diagnosis was rarely seen and most of the patients
were in the advanced stage of the disease, so
awareness of medical check up should be aroused
among the citizens. Lack of facilities and of
funding by the government is an important factor
contributing to a lower success rate in the
treatment so more help from the government can
improve the conditions.
