Show more >Background. - Four patterns of left ventricular (LV) geometry (normal, concentric remodelling, concentric hypertrophy and eccentric hypertrophy) have been described in aortic stenosis (AS). Although LV concentric remodelling (LVCR), characterized by normal LV mass despite increased LV wall thickness, is frequently observed in AS, its prognostic implication has been not specifically studied. Aim. - We aimed to assess, using echocardiography, the prognostic implication of LVCR in asymptomatic or minimally symptomatic patients with AS. Methods. - Overall, 331 patients (mean age 73 +/- 13 years; 45% women) with AS (aortic valve area <= 1.3 cm(2)) and an ejection fraction > 50% were enrolled. The endpoints were mortality with conservative management and mortality with conservative and/or surgical management. Results. - Sixty-three (19%) patients died under conservative management (follow-up 29 1 months). The highest risk of mortality under conservative management compared with patients with normal LV geometry was observed for LVCR (adjusted hazard ratio [HR]: 3.53, 95% confidence interval [CI]: 1.19-10.46; P = 0.023), followed by concentric LVH (adjusted HR: 2.97, 95% CI: 1.02-8.60; P = 0.045). Aortic valve replacement was performed in 96 patients (29%) during the entire follow-up (37 +/- 1 months); 72 (22%) patients died. Only LVCR remained independently associated with an increased risk of mortality when surgical management during the entire follow-up was considered (adjusted HR: 2.93, 95% CI: 1.19-7.23; P = 0.020). Conclusions. - Among the patterns of LV geometry in AS, LVCR portends the worst outcome. Patients with LVCR and AS have a considerable increased risk of mortality, regardless of clinical management.
