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.
