Objective — to analyze the results of aortic root replacement using valved conduit with aortic valve bioprosthesis and easy change system. Material and methods. There were 3 procedures of aortic root replacement using biological valved conduit with «easy change» system and coronary ostia reimplantation in accordance with Bentall—De Bono technique. All surgeries were performed at the Cardiovascular Surgery Department of the Cardiology Research Institute of the Tomsk National Research Medical Center of the Russian Academy of Science in March 2019. There 3 men aged 65, 69 and 70 years with acquired aortic valve disease and aortic root aneurysm. Transthoracic echocardiography was made prior to surgery and at discharge (14 days after surgery) in order to assess the aortic valve and left ventricle function. Results. A 65-year-old patient was diagnosed with aortic stenosis, peak and mean pressure gradient up to 95 and 63 mm Hg, respectively, effective orifice area of the aortic valve 1.5 cm2 and aortic root aneurysm up to 60 mm. A 70-year-old patient had congenital connective tissue dysplasia, severe aortic regurgitation and ascending aortic aneurysm up to 56 mm. A 69-year-old patient had infectious endocarditis, severe aortic regurgitation and aortic root aneurysm. In 14 days after surgery, peak pressure gradients were 23, 39 and 32 mm Hg for the prostheses 25, 23 and 27 mm, respectively. Mean pressure gradients were 12, 21 and 17 mm Hg, respectively. Conclusion. Initial experience of implantation of biological valved conduit with «easy change» system demonstrated satisfactory hemodynamic results and convenience of implantation with possible simplification of redo valve replacement.
