Intermediate-Term Outcomes of 3F Stentless Bioroot for Bentall Operation

Abstract

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.
