Valvular & structural heart diseaseCohort study
Sex Differences in Left Ventricular Remodeling for Risk Stratification of Patients With Aortic Regurgitation
- Multicentre cohort study
- 5 centres (Netherlands, Singapore, Hong Kong, Canada, Romania)
Authors' conclusion
In this study among individuals with moderate-severe AR, similar LVESDi thresholds (20 mm/m2) for both sexes, but lower than currently recommended by guidelines, were independently associated with mortality. In turn, LVESVi thresholds were 40 mL/m2 for women and 45 mL/m2 for men
Study context
- Population
- Patients with moderate-severe aortic regurgitation and preserved LV ejection fraction (LVEF) (≥50%), asymptomatic, 2003–2022323 underwent aortic valve surgery (AVS)

- Exposure
- Women vs men
- Womenn = 320
- Menn = 488reference
- Outcome
- All-cause mortality during medical management and following aortic valve surgery
- Follow-up
- Median (IQR) 7 (4-11) years
