title: [Severe aortic stenosis without left-ventricular hypertrophy: associated variables and prognosis following aortic valve replacement].
abstract: The purpose of the present study in patients with severe aortic stenosis was to assess prevalence, predictors and course after aortic valve replacement in patients without left ventricular hypertrophy according to echocardiographic mass criteria (LVH). 90% had LVH compared with 10% without. The following variables were associated with absence of LVH: younger age, low body surface area, and increased cardiac index. In patients with LVH, ventricular adaptation following aortic valve replacement was adequate more often than in those without. Six-month mortality following aortic valve replacement was insignificantly lower in patients with LVH (7.6%) than in those without it (12.5%, p = 0.10).
