Echocardiographic characteristics of the study patients
Regarding the echocardiographic parameters, LV volume, LVEF and
prevalence of moderate to severe mitral regurgitation did not show a
significant difference between groups both at the time of implantation
and the most recent examination (Table 2). Prevalence of the patients
with improved LVEF ≥5% or 10% or a decreased LV end-diastolic volume
did not differ between groups.
