Methods Between 27 10 99 and 19 01 08 the No-React BioConduit composite graft was implanted in 67 patients. Data on these patients were collected from the in-hospital database from patient notes and from questionnaires. A cohort of patients had 2D-echocardiogram with an average of years post-operatively to evaluate valve function calcification and the diameter of the conduit. Results Implantation in 67 patients represented a follow-up of patient-year. Males were 60 of the operated population with a mean age of years range years 21 of them below the age of 65. After a mean follow-up of years range of years more than 50 of the survivors were in NYHA I II and more than 60 of the survivors were angina-free CCS 0 . The overall 10-year survival following replacement of the aortic valve and root was 51 . During this period 88 of patients were free from valved-conduit related complications leading to mortality. Post-operative echocardiography studies showed no evidence of stenosis dilatation calcification or thrombosis. Importantly during the 10-year follow-up period no failures of the valved conduit were reported suggesting that the tissue of the conduit does not structurally change histology of one explant showed normal cusp and conduit . Conclusions The No-React BioConduit composite stentless aortic valved conduit provides excellent long-term
