Abstract
OBJECTIVES This study investigated sex-based differences in outcomes after mitral valve (MV) surgery for severe ischemic mitral regurgitation (SIMR). BACKGROUND Whether differences in outcomes exist between men and women after surgery for SIMR remains unknown. METHODS Patients enrolled in a randomized trial comparing MV replacement versus MV repair for SIMR were included and followed for 2 years. Endpoints for this analysis included all-cause mortality, major adverse cardiovascular and cerebrovascular events (MACCE) (defined as the composite of death, stroke, hospitalization for heart failure, worsening New York Heart Association functional class or MV re-operation), quality of life (QOL), functional status, and percentage of change in left ventricular end-systolic volume index (LVESVI) from baseline through 2 years. RESULTS Of 251 patients enrolled in the trial, 96 (38.2%) were women. Compared with men, women had smaller LV volumes and effective regurgitant orifice areas (EROA) but greater EROA/left ventricular (LV) end-diastolic volume ratios. At 2 years, women had higher rates of all-cause mortality (27.1% vs. 17.4%, respectively; adjusted hazard ratio [adjHR]: 1.85; 95% confidence interval [CI]: 1.05 to 3.26; p = 0.03) and of MACCE (49.0% vs. 38.1%, respectively; adjHR: 1.58; 95% CI: 1.06 to 2.37; p = 0.02). Women also reported worse QOL and functional status at 2 years. There were no significant differences in the percentage of change over 2 years in LVESVI between women and men (adjβ: -10.4; 95% CI: -23.4 to 2.6; p = 0.12). CONCLUSIONS Women with SIMR displayed different echocardiographic features and experienced higher mortality and worse QOL after MV surgery than men. There were no significant differences in the degree of reverse LV remodeling between sexes.
