A) In this picture is shown a normal mitral valve in situ and a surgical needle passing through the “mitral annulus”. B) Here we recreate a surgical mitral valve replacement with a biological valve to show the importance of having in mind the anatomical relationship with the structures of the left atrioventricular groove during the procedure.  LA: Left Atrium; MV mitral valve; 1: circumflex artery; 2: Biological mitral valve prosthesis.
