“…Over the past decade, many isolated cases of mitral valve homograft, particularly in those with endocarditis 10,11 or in children, 12 and small series with short-term follow-up 13,14 have been published. Intermediate-term results (5 years) have been a matter of controversy.…”

“…This theoretical concept was experimentally proved and is clinically applied by preservation of the chordae tendineae and by implantation of mitral valve homografts. Theoretically, artificial chordae implantation and mitral valve homograft implantation is considered the ideal treatment in cases where the preservation of the natural subvalvular apparatus is not feasible (6,7,8). The arrangement and classification of the chordae including the anatomy of the entire valve complex have been described by Walmsley(9) and then more by Lam et al (10) in details.…”

Mitral homograft replacement requires a good knowledge about anatomy of the papillary muscles. In 60 (38 male, 22 female) cardiac preparations of various age (16-44 ages), branch distribution of the chordae tendineae and level of their fixation to the ventricular surface of the right and left cusps of mitral valves have been studied. Papillary muscles and chordae tendineae were examined and their geometrical arrangement was determined. Three groups of the left ventricular papillary muscle were defined. In group I (43.3%, 52/120) the basal part and the apex of the muscle were undivided. In group II (30%, 36/120) there were two heads; in subgroup II/A (20%, 36/120) the base of the papillary muscle was undivided and in II/B (10%, 12/120) it was divided into two separate parts. In group III (26.7%, 32/120) the papillary muscle had three heads. It was also observed that 2 to 15 chordae tendineae can originate from the apex of papillary muscle and 9 to 60 chordae tendineae can ended into the corresponding half of the valve insertions. Thus these definitions and morphologic types may be of great value during endoscopic and conventional mitral valve replacement or reconstruction of the chordae tendineae and in mitral valve homograft implantations.

“…The most frequent indication for late reoperation was degeneration of the mitral homograft. [11][12][13] Reintervention on mitral homografts was not particularly technically challenging and removal of prosthetic ring as first step during the procedure is recommended. One death in our series was due to technical difficulty in replacing an entirely calcified aortic homograft root.…”
