Echocardiographic improvement in MR and TEE findings
In the present study, in accordance with the guides, at least 0,1
cm2 reduction in ERO or at least 15ml decrease in RV
was considered as echographic improvement of MR (Responder /
Non-responder). There were 19 patients with at least 0,1
cm2 reduction in ERO, 9 patients with at least 15ml
decrease in RV and 8 patients who fulfilled both parameters.
No statistically significant difference was found between patients with
and without at least 0.1 cm2 decrease in ERO and
between those with and without 15ml decrease in RV with regard to
demographic characteristics. Table 4
No significant difference was found between patients in whom regarded as
responder or non-responder according to status of change ERO, (Table 5)
with respect to mitral annulus area, posteromedial and anterolateral
diameter , antero-posterior diameter and anterior leaflet angle (p
> 0,05). Yet, it was established that posterior leaflet
angle was significantly lower in responder patients than that in
non-responder patients. (p = 0,029) (40,73 vs. 32,47, p = 0,029).
No significant difference was found between three dimensional TEE
paramers of patients in whom regarded as responder or non-responder
according to status of change RV in terms of 3D TEE parameters. (Table6)
However,, similar to the result obtained in ERO changes, in the
responder group there was a trend towards lower posterior leaflet angle
compared to non-responder group. . ( respectively 29,22 vs. 38,19 p =
0,063)
In the group with whom regarded as responder or non-responder according
to status of change ERO and RV both, When 3D TEE parameters were
compared, statisicallly significant difference was found in posterior
leaflet angle (p < 0,05). It was established that in
non-responder group, posterior leaflet angle was higher.
(38,05 vs. 28,5 p = 0,049).
(Table 7)
Although posterior leaflet angle was found to be significantly different
between responder and non-responder patients, in logistic regression
analysis performed to determine the independent predictor parameters of
MR improvement, it was not found to be significant.
