The morphometry of the accessory leaflets of the tricuspid valve in a four cuspidal model
Folia Morphol 2007;66(4):323-327.
Abstract
The tricuspid valve is of great importance because of the progress made in
operative techniques and invasive cardiology accidents. This structure is more
differentiated during evolution than the mitral valve. Accessory leaflets, their
frequency and role are still controversial, despite the fact that they have been
known from the beginning of the 20th century. The number of leaflets in the
tricuspid valve grows in an evolutionary line, but the rules governing their
appearance are still not known. The samples were taken from a group of
107 human adult hearts. The four-cuspidal form of the tricuspid valve was
used as the simplest model to show the appearance of accessory leaflets for
anatomical and statistical examination. On the basis of the results of this
study we conclude that the separation of accessory leaflets is a complex
process.
