Abstract
The pulmonary artery pressure and left ventricle dimension &
EF were studied in 20 patients with severe MS before ,
immediatily after and 3 months after successful PBMV by Echo-
Doppler to evaluate the effects of optimal valvotomy on these
parameters.
Results of this study were shown in tables 5 to 16 and
summerised as the following :
The MVA increased from 1.03 ± 0.14 Cm2 to 1.93 ± 0.13
Cm2 immediately after and to 1.83 ± 0.15 Cm2 3 month after the
procedure .
The PASP decreased from 52.05 ± 16.16mmHg to 36.95 ±
12.8mmHg immediately after and to 31.2 ± 12 mmHg 3 months
after the procedure.
Fifteen patients (75%) showed decreese of PASP to near
normal and 5 patients (25%) showed persistently elevated PASP.
Patients who showed persistently elvated PASP were more
likely older in age, with higher echoscores, smaller mitral valve
area and higher PASP before the procedure.
Global left ventricular fuction (EF%) were improved from
56.8 ± 6.1 to 62.2 ± 5.1 and this was due to increased left
ventricular enddiastolic dimentions from 49.65 ± 2.8 to 52.6 ± 2.4
66
mm and slight decrease of endsystolic dimention from 33.45 ± 3.1
to 33.15 ± 3.0 mm after the procedure.
The left atrial size decreased from 43.4 ± 5.9 to 41 ± 6mm.
All patients showed improvement of the functional class :
class III/IV (3 Vs 0), class II (17 Vs 2) and class I (0 Vs 18).
These ruslts were tabled and statistically evaluated.
