The fate of mild-to-moderate proximal aortic dilatation after isolated aortic valve replacement for bicuspid aortic valve stenosis: a magnetic resonance imaging follow-up study

The treatment of mild-to-moderate aortic dilatation at the time of aortic valve replacement (AVR) in patients with bicuspid aortic valve (BAV) disease is still controversial. We aimed to estimate late progression of aortopathy in patients who underwent isolated AVR for BAV stenosis with concomitant proximal aortic dilatation of ≥40 mm. The review of our institutional BAV database ( n = 510) revealed a subgroup of 96 consecutive BAV patients (57...
