**2.3 Double valve destructive infective endocarditis treatment with monoblock aortomitral homograft implantation**

A 56-year-old male patient with subacute infective endocarditis (presumably from September 2021) with aortic (severe failure) and mitral (severe failure) valve involvement and aortic root abscess was operated on in June 2022. The patient had a commonplace clinical course of infective endocarditis that had been confirmed under current guidelines before admission. Considering the limited but promising world experience with monobloc aorta-mitral homografts, we assumed that monobloc aortomitral homograft implantation could be an alternative to the "standard" Commando procedure. The median sternotomy approach and standard cardiopulmonary bypass with bicaval cannulation and cold cardioplegia. This technique used in our clinic entailed several steps described below.
