Abstract:
This research was performed to study the role of
diagnostic investigations (Chest X-ray) also
(Echocardiography) in the diagnosis of mitral valve stenosis
and how to dilate it by Inoue balloon under (fluoroscopy) and
explain the different effects of the disease upon thirty two
patients of approximately 18 to 46 years old, 8 of them were
males and the rest were females. The percentage of them are
(25% males and 75% females). The study (Chest X-Ray)
show that the cardiomegaly appeared in 68.75% of patients
and 91% of them there is a left atrial enlargement also 62.5%
have a left ventricular enlargement, 47% of them the carinal
angle widened, the kerly,s B lines appeared in 25%, edema
appeared in 53% of them, the other diseases, such as: (small
heart, hyper inflated lungs, emphysema, right sided
pneumothorax, pneumonia, right sided pleural effusion and
encysted pleural effusion) appeared in 18.75% of them.

Also the study (Echocardiography) show that 91% of the
patients appeared that the left atrial enlarged and appeared
normal in size of 9 % of them, also 78.125% of the patients
have a severe mitral stenosis . 12.5% of them have a
moderate stenosis.9.375 % of patients have a mild stenosis .
3.125 % of patients have a severe mitral regurgitation
(severe MR) through the mitral valve and the same
percentage (3.125%) have a moderate regurgitation
(moderate MR ), 21.5% of them have a mild regurgitation
(mild MR), 12.875% have a trivial regurgitation (trivial MR)
and the huge percentage of them 59.375% have not
regurgitation (No MR ) .
The study of echo shows that in all of the patients there
is no clot in the left atrium (100%) the dilatation of mitral valve
or percutaneous transluminal mitral commissurotomy
(PTMC) could not done if there is any left atrial clot because
the clot may obstruct the way of the catheter and if it
fragmented propagate with the blood stream until to reach the
brain and causes many problems. The study done to
measure the pulmonary artery pressure (PAP) by the echo
show that it is not normal in all the patients, 00% because all
of them complain of mitral stenosis. 34.375 % have a mild
pulmonary artery pressure, 21.875% moderate and 43.75%
have a severe pulmonary artery pressure.
Also the study under (Fluoroscopy) to dilate the mitral
valve show that the length of the patients (145mm-160mm)
resembled 62.5%, (160mm-180mm) take 34.375% and
(180mm-200mm) has a 3.125%. The balloon size used for
dilatation, the size (24mm) 9.375%, (26mm) 65.625%,
(28mm) 25% and (30mm) not used so that resemble 00%.
The number of inflations as follow, single inflation 59.375%,
double inflations 25% and graded inflations 15.625%.

The cathetrization show that 6.25% of the patients have
a severe mitral regurgitation (severe MR), 3.125% have a
moderate mitral regurgitation (moderate MR), 18.725 % have
a mild mitral regurgitation (mild MR) and the same
percentage of them have a trivial mitral regurgitation (trivial
MR) and there is a huge amount of the patients have not any
mitral regurgitation (No MR). The study show that the
transmitral gradient before dilatation between
(06mmHg-14mmHg) was 31.25%, (15mmHg-23mmHg)
59.375% and (24mmHg-32mmHg) 09.375%.
And hence we measured the transmitralgradient after
the dilatation and we noticed that it decreased to (00mmHg)
18.75%, (02mmHg-04mmHg) 62.50% and between
(05mmHg-08mmHg) was 18.75%.
Also we measured the pulmonary artery pressure (PAP)
before the dilatation and we found that no there is no normal
(PAP) in all patients . it is mild in 06.25%, moderate in
56.25% (it is the highest percentage) and a severe in 37.50%
of them.
After dilatation the pulmonary artery pressure was
normal in 18.75% of the patients, mild in 43.75% (it is the
highest percentage), moderate in31.25% and a severe in
06.25% of them. The complications appeared in tow patients
06.25% and no there is no complications in the rest 93.75%.
Finally the results were good in 93.75% of patients and not
good in 06.25% of them.
