All 43 patients underwent successful TMVI procedure without significant
residual regurgitation and stenosis.
However, one patient with
transcatheter mitral ViR implantation developed SAM and severe LVOT
obstruction leading to hemodynamic instability. As shown in Table 1, 24
patients (56%) had TMVI for degenerated bioprosthetic valves, 7
patients (16%) had TMVI for failed repair with annuloplasty rings, and
12 patients (28%) had TMVI for native MV diseases; 8 had severe
functional mitral regurgitation, 3 had severe mitral stenosis or
regurgitation due to mitral annular calcification, and 1 had rheumatic
heart valve. Two patients were implanted balloon-expandable
transcatheter stent valves size 23 mm, 7 were implanted stent valves
size 26 mm, and the remaining patients (79%) were implanted stent
valves size 29 mm (Table 2).
