Table 17. Primary MR Intervention (cont'd)
Recommendations COR LOE
Concomitant mitral valve repair is reasonable in patients with
chronic moderate primary MR (stage B) when undergoing
cardiac surgery for other indications.
IIa C
Mitral valve surgery may be considered in symptomatic
patients with chronic severe primary MR and LVEF <30%
(stage D).
IIb C
Transcatheter mitral valve repair may be considered for
severely symptomatic patients (NYHA class III to IV) with
chronic severe primary MR (stage D) who have favorable
anatomy for the repair procedure and a reasonable life
expectancy but who have a prohibitive surgical risk because
of severe comorbidities and remain severely symptomatic
despite optimal guideline-directed management and therapy
(GDMT) for HF.
IIb B
MVR should NOT be performed for the treatment of isolated
severe primary MR limited to less than one half of the
posterior leaflet unless mitral valve repair has been attempted
and was unsuccessful.
