Background: Aim of this study was to assess the intermediate-term outcome after Bentall operation using a self-assembled bio-root conduit containing a 3F stentless valve. Between April 2010 and August, 2015, 30 patients affected by aortic root dilatation with aortic valve disease underwent Bentall operation at our Unit, using a conduit assembled by including a 3F ® stentless valve into a straight woven tube graft. Mean age at surgery was 66.3 yrs. Mean Logistic EUROscore was 10.01. Mean pre-operative Ejection Fraction was 54.50%. Two patients (6.3%) had undergone a previous operation. Three patients (10%) had a bicuspid valve. Five patients (16.6%) received an associate procedure. Mean size of bio-root was 28.93. Mean ischemic time was 101.43', mean CPB time 127'.Results: All patients were evaluated by echocardiogram and clinical examination at discharge and annually. Median follow-up time was 6.94 years. Primary end points of our analysis consisted of early and late mortality, freedom from ABE and MACCE, freedom from SVD and freedom from valve-related reoperation. Early mortality was 0%. Two patients died during follow-up, one for cardiac causes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
