ABSTRACT
AIMS: Native T1 times from T1 mapping cardiac magnetic resonance (CMR) are associated with myocardial fibrosis in aortic stenosis (AS). We investigated whether changing patterns in native T1 predict clinical outcomes after aortic valve replacement (AVR) in severe AS patients. METHODS AND
RESULTS: Forty-three patients with severe AS (65.9?±?8.1?years; 24 men) who underwent T1 mapping CMR at baseline and 1?year after AVR were prospectively enrolled. Upper limit of native T1 from healthy volunteers was used to define normal myocardium and diffuse fibrosis (native T1?
