Baseline characteristics
Forty-six of the 47 (98%) patients who underwent TMVI between October
2014 and October 2019 were enrolled in this analysis. The age of the
study population was 72±9 years (74% males; n=34) (Table 2). All were
New York Heart Association (NYHA) functional classes III or IV. All
patients had ≥grade 3+MR before TMVI and most patients (91%) had
secondary/functional MR (predominantly due to ischemic leaflet
tethering) (Table 2). In patients with an LVEF 35-50%, 54% had an EROA
≥0.4cm², and in patients with an LVEF ≤35%, all patients had an EROA
≥0.2cm². Baseline demographic and TTE characteristics of the study
population are reported in Tables 2 and 3.
