Objectives In patients with aortic stenosis (AS) left ventricular (LV) myocardial growth may exceed individual needs to compensate LV haemodynamic load leading to inappropriately high LV mass (iLVM), a condition at high risk of adverse cardiovascular events. The prognostic impact of iLVM was determined in 218 patients with asymptomatic severe AS.

Methods iLVM was recognised when the measured LV mass exceeded 10% of the expected value predicted from height, sex and stroke work (prognostic cut-off assessed by a specific ROC analysis). For assessment of outcome, the endpoint was defined as death from all causes, aortic valve replacement or hospital admission for non-fatal myocardial infarction and/or congestive heart failure.

Results At the end of follow-up (22+13 months) complete clinical data were available for 209 participants (mean age 75+11 years). A clinical event occurred in 81 of 121 patients (67%) with iLVM and in 26 of 88 patients (30%) with appropriate LV mass (aLVM) (p<0.001). Event-free survival in patients with aLVM and iLVM was 78% vs 56% at 1-year, 68% vs 29% at 3-year and 56% vs 10% at 5-year follow-up, respectively (all p<0.01). Cox analysis identified iLVM as a strong predictor of adverse outcome (Exp β 3.08; CI 1.65 to 5.73) independent of diabetes, transaortic valve peak gradient and extent of valvular calcification. Among patients with LV hypertrophy, those with iLVM had a risk of adverse events 4.5-fold higher than counterparts with aLVM.

Conclusions iLVM is common in patients with asymptomatic severe AS and is associated with an increased rate of cardiovascular events independent of other prognostic covariates.
