Abstract
A biological heart valve replacement, particularly for pediatric patients, comprises a tubular segment (A) comprising a proximal end (Ep), a distal end (Ed) and a central portion (Pc) arranged between said proximal and distal ends and defining a longitudinal direction of the valve. The valve further comprises at least one inner leaflet (C) attached in hinge-like manner to a connection zone (F) at an inner wall (W) region of said central portion, each one of said inner leaflets being movable between a closing position and an opening position of the valve. In order to provide growth adaptability, the tubular segment comprises at least one tubular growth zone (B; B,B) configured as a longitudinal strip made of a growth-adaptive biomaterial, with the remainder of the tubular segment being made of a non-growth-adaptive biomaterial.
