Methods
Between 2009 and 2018 all cases ATAAD treated at Royal Brompton and
Harefield NHS Foundation Trust were analysed. Patients were divided into
2 groups: a) ascending aorta (interposition) graft (AAG) without valve
replacement; and b) non-valve-sparing aortic root replacement (ARR).
Pre-operative covariates were compared, as well as operative
characteristics and post-operative complications. Long-term survival and
echocardiographic outcomes were analysed using regression analysis.
