Half of inpatients who undergo aortic valve replacement develop new-onset atrial fibrillation, a US study suggests.

The incidence of new-onset atrial fibrillation was 50.4% among transcatheter aortic-valve implantation (TAVI) hospitalisations and 50.1% among surgical aortic valve replacements, University of Minnesota researchers reported.
