Key result
LVESVi ≥45 mL/m2 is linked to increased mortality risk in asymptomatic chronic AR.
Why the study?
Do echocardiographic LVESVi and Vol-LVEF predict mortality risk as well as LVESDi and linear LVEF in asymptomatic patients with hemodynamically significant chronic aortic regurgitation?

In asymptomatic chronic aortic regurgitation, volume-derived echocardiographic parameters (LVESVi ≥45 mL/m2) are effective for risk-stratifying mortality, performing equally to traditional linear measurements.

LVESVi ≥45 mL/m² may aid mortality risk stratification in asymptomatic AR; extends linear measures but leaves open guideline adoption pending RCTs.
In this large asymptomatic cohort of patients with hemodynamically significant AR, LVESVi and Vol-LVEF worked equally as well as LVESDi and linear LVEF in risk discriminating patients with excess mortality. A LVESVi threshold of 45 mL/m2 or greater was significantly associated with an increased mortality risk.
