Additional papillary muscle relocation (PMR) specifically addresses leaflet tethering to restore mitral valve geometry.

A total of 51 patients underwent annuloplasty and additional PMR (study group). A total of 54 patients underwent isolated annuloplasty (control group).

The primary composite end point was significantly improved in the study group (19.6% [10\/51]) in comparison to the control group (44.4% [24\/54]; P\u2009=\u20090.009). Two-year all-cause mortality was 7.8% [4\/51] in the study group vs 18.5% [10\/54] in the control group (P\u2009=\u20090.098).
