Small aortic root in aortic valve stenosis: clinical characteristics and prognostic implications

Aims In aortic valve stenosis (AS), having a small aortic root may influence both the assessment of AS severity and the treatment strategy. The aim was to test the prognostic implications of having a small aortic root in AS within a large prospective study. Methods and results We used data from 4.3-year follow-up of 1560 patients with asymptomatic, initially mostly moderate AS enrolled in the Simvastatin and Ezetimibe in Aortic Stenosis study. A small aortic root was defined as inner aortic sinotubular junction diameter indexed for body height
