Abstract
Studies of the morphometry and normal anatomy of the tricuspid valve are in
constant demand. Knowledge of the morphology of the normal tricuspid valve
may be useful, for example in the context of the transfer of a leaflet of the
tricuspid valve for repair or insufficiency of the mitral valve, in repair of the
tricuspid valve after blunt chest trauma and in other surgical techniques of this
region. In this study, performed in a group of 107 formalin-fixed adult human
hearts, we attempted to assess the form and number of the main and accessory
cusps in the tricuspid valve. Rare anatomical variants of the tricuspid valve were
found. Using a planimeter we evaluated the surface area of the tricuspid valve
and particular leaflets. With the help of a Vernier scale we measured the length
and height of individual leaflets of the tricuspid valve and the length of the
commissures. No differences were found between the length of the anterior
and septal leaflets. The posterior leaflet was the shortest, while the anterior
leaflet was the widest and had the largest surface area. The posterior leaflet
was wider than the septal leaflet and had the smallest surface area. No differences
were found between the main and accessory leaflets in the length of
the commissures.
